administrator(s) for details. If you don't have access to news, you
may still be able to post messages to the group by using a mail server
like anon.penet.fi (mail [e-mail] for more information).

Each issue of the digest contains one or more sets of articles (called
threads), with each set corresponding to a 'discussion' of a particular
subject.  The articles are not edited; all articles included in this digest
are in their original posted form (as received by our news server at
ee.mcgill.ca).  Article threads are not added to the digest until the last
article added to the thread is at least two weeks old (this is to ensure that
the thread is dead before adding it to the digest).  Article threads that
consist of only one message are generally not included in the digest.

Subject: **** ANSI C Array HELP ****
Date: Thu, 19 Sep 1996 15:17:29 -0400
Organization: University of Connecticut

I am working on a program that passes arrays.  I need these arrays to be
updated in one function and then the results printed out in another, IAW:


void function_a(void)
   {
   float *array[20];      // I NEED this to be a pointer
   int i

   for(i=1;i<=10;i++)          // I need to initialize the data in the array
      ??? array[i]=i;

   function_b( ??? array);     // Then I need this to pass an address, How????

   for(i=1;1<=20;1++)
      printf("%10.4f",array[i]);
   }


If anyone can help, I would greatly appreciate it (e-mail me directly
too).  I have done this before, but I can't remember it, and I don't have
my old code available.



Thanks,

Well, there are several problems with how you're doing it here.

Maybe so, but you also need something for the pointers to point TO.  Before
you can initialize what is being pointed at, you really need to point to
something.

Assuming that you had set the pointer in question to the address of a float,
here you'd use
         *array[i] = i;

         function_b(&array);     // Will pass the address of the array

Why would you want to print out the addresses in float format?  Use
      printf("%10.4f", *array[i]);  // Prints the values, not the addresses

I think you missed something.

The whole problem with the original poster's code is that the above
declaration should simply be:

float array[20];

With that change, the rest of the code should be fine.

Chris:

Try this:
void function_a(void)
{
    float array[20];      <- the array name itself is a pointer
    int i;

    for(i=1;i<=10;i++)      <- NOTE: Your array init should start at 0
!!!!
       array[i]=i; <- no explicit pointer dereference needed here (i.e.
no '*' needed; code is ok like this)

    function_b(array);     <- just pass the array name; your function_b
should be: function_b(float* array)
                                              or function_b(float[]
array), I can't remember which is better

    for(i=1;1<=20;1++)      <- AGAIN: start at 0 !!!
       printf("%10.4f",array[i]);
}

I just tried this using Symantec C++ v 7.0.4 compiler on the Mac, and
it worked a-o.k.

I seem to remember some compilers choking on passing arrays of float in
this manner, but I can't be sure. Memory's not what it used to be.

Hope this helps,
-Chuck.

Here's one way to do it. In C/C++ the name of an array is effectively a
pointer to the first element of the array. You don't need to do anything
tricky with the declarations.


const int kArraySize = 20;

void function_a(void)
{
    float array[kArraySize];

    // initialize the array

    for ( int i = 0; i < kArraySize; ++i )
        array[i] = i;

    function_b(array, kArraySize);

    for ( int i = 0; i < kArraySize; ++i )
        printf("%10.4f\n", array[i]);
}

void function_b(float *array, int n)
{
    for ( int i = 0; i < n; ++i )
        array[i] = 2.0 * array[i];
}

From [e-mail] (Tom Emerson)
Subject: ANNOUNCE: AGMenu 1.0 final release
Date: Mon, 23 Sep 1996 15:34:33 -0400
Organization: Apple Computer, Inc.

This message announces the availability of AGMenu 1.0.

AGMenu is a small library which manages the Guide (or Help, or Balloon
Help, or Question) Menu for you, letting you stash your application's
Apple guides in their own folder, out of the way of inquisitive users.
AGMenu places your guides in the correct locations in the menu, and uses
the same criteria that Apple Guide 2.0 uses when decided which guides
should be included. Integrating AGMenu into your application is trivial
and can often be done in less than an hour.

AGMenu's capabilities are superseded by Apple Guide 2.1, which adds the
ability to search an alternate directory for an application's guide files
without changing your application's code. AGMenu detects when Apple Guide
2.1 (or later) is installed and does nothing, letting the System take care
of things. The advantage of AGMenu is that it works regardless of which
version of Apple Guide you're using.

AGMenu will work with all of the Macintosh C, C++, and Pascal development
environments, and includes information on using it with PowerPlant and the
THINK Class Library. It also works with the Mercutio MDEF.

The release notes for AGMenu can be found on the World Wide Web at

    <http://www.tiac.net/users/tree/AGMenu.html>

You can obtain AGMenu via anonymous ftp from

    <ftp://ftp.cambridge.apple.com/pub/users/tree/AGMenu1.0.hqx>

It has also been submitted to macgifts.

NB: AGMenu is not an Apple supported product.

You may use AGMenu freely in your programs, all I ask is that you let me
know that you are using it so I can keep you informed of changes and
enhancements. If you feel like giving credit in an about box or sending me
a copy of your software, that would be super too.

Changes from 1.0d3:

- Removed AGMenuKey and AGMenuSelect from the API. AGMenu now patches
  MenuKey and MenuSelect, allowing it to be used without modifying user
  code.

- Ignores new Mac OS 8 guide file types.

- Fixed serious lossage in the Pascal interface file (and actually
  tested it!)

- When opening a guide file AGMenu will wait for the application portion
  of Apple Guide to start (if necessary) before calling AGOpen. This works
  around a problem where Apple Guide doesn't wait long enough for the
  application portion to start if it starts it up.

Enjoy.

You need to use UPPs and declare everything correctly.

Of course, a bit more descriptive troubleshooting would help.

"still don't work" is insufficient information to go on.

Subject: Application Merge
Date: 22 Sep 1996 12:10:00 -0400
Organization: America Online, Inc. (1-800-827-6364)

This sounds like an odd, unorthodox question, and yes, it probably is.

I want to "merge" an application with another (or in my case, a control
panel).  My question is, can I "launch" this application from within the
main one (or control panel)?

I know how to write/open/use external code resources, and find it an
invaluable tool (since I might use a certain bit of code in ALL my
programs, I can make the code an external resource).

I've already designed the code to copy *all* the resources over (since it
is a control panel, I don't run in to any ID conflicts...except for
version info, which can be removed anyway) from the target application to
my control panel.  Would I simply open the 'CODE' resource number 0?  Or
is it more complicated than that?

Thanks,
Alex Rampell

To launch an embedded application from within a control panel all you
have to do
is find out the FSSpec of your control panel and stuff this information
into a
LaunchParamBlock and then call the LaunchApplication() function.
I have done this and it works like a charm, but you might perhaps supply
some
additional information to LaunchApplication(). Since I'm writing this
off amy head
without access to my sources, I'm not sure about the exact information
needed by
LaunchApplication(), but the above is it in a nutshell.

To have a second application inside another one IMO would always yield a
resource ID
conflict at least for classic (non CFM) 68k apps since both would
require at the very
least a 'CODE' 0 resource.

>>>>>>>

I'm not sure if you were referring to sample code ("but the above is it in
a nutshell")

What I'm going to do, more specifically, is launch this from an INIT.
This appears to be a daunting task, so before I embark upon it, I'd like
to know a few things.

I'm not really sure how to use LaunchApplication to open an embedded
'CODE' resource, but I do know how to create an FSSpec to one's self.
This is what I do upon startup; when the "first time" code (not the patch)
runs, it creates an FSSpec to itself that is stored in a global that the
patch accesses.

So I guess I want to UseResFile (from the INIT) to the FSSpec that I've
created, and then Launch the CODE resource (I'm not completely sure how to
do this...there won't be any resource conflicts, as this is a cdev/INIT).

The problem (that I've thought about) is in the following:
Since the INIT is in the System Heap, I'll be OK saying UseResFile, but
then I have to switch it back, right?  However, as this application is
completely independant from my INIT, I won't know when this happens,
unless I patch some more traps.  Is there any way around this problem?

Will I be calling LaunchApplication, or just opening the 'CODE' resource?

This is a complicated question (or at least I think so...).  Any help
would be greatly appreciated.

Thanks,
Alex Rampell

Hi all,

examining the constants which help to determine the baudrate of the
serial driver, one finds that
   value_to_pass := (115200 div baudrate) - 2
gives the value for all baudrates.

But I wonder why there is an offset of 2 ? Does anybody know the reason?

AFAIK thats how the Zilog 8530 chip wants the value. If you want to use
the "normal" baudrates, eg. 1200, 2400, .. you should use the predefined
constants as described in Inside Macintosh .
Hope that helps,

Subject: Folder selection madness
Date: Wed, 18 Sep 1996 09:27:55 -0700
Organization: Electric Fish, Inc.

OK, I have a CustomGetFile modification that allows the user to choose a
folder.   What I cannot seem to do is get it to select a particular folder
when it comes up.  I have no trouble specifying the parent directory in
the usual way, but the damn thing insists on picking some other random
folder as the initial selection.  I have tried specifying the folder
itself as the starting point, which results in some random folder _inside_
the starting point being selected; and I have tried selecting the folder
itself inside its parent directory, which results in the last folder in
the list being selected.

Has anyone managed to do this?

(N.B.  I have seen the source code from IM-Files and at least two PD
libraries for choosing folders.  None of them address this problem.)

The real question is, how are you doing this?  By slamming CurDirStore and
SFSaveDisk before calling CustomGetFile?  That definately won't work because
of General controls and StuperBoomerang.

What you need to do is use a filter and slam these on or about your first
call, which should be after the other guys slam them.

Good luck.

Does anyone here remember aone of the earliest Mac games, called Feathers

while evil birds try to carry away the humans and crash into the rescue
ships. It was one of the very earliest games for Mac, innovative for its

Hmm, I think MacSlots would be a candidate for first commercial game.
There were quite a few Infocom games early on, too. Also, there was a
pretty good little backgammon game that was shareware or freeware, and it
still works!

I'd have to vote for that Alice in Wonderland chess game that came from
Apple "Through the Looking Glass" by Steve Capps (you know, the one that
shipped in a box designed to look like a book).  It has a copyright of
1984.  And I've even got a copy still in shrinkwrap with the "Macintosh

The way to get a nice, sorted list just like you'll see in a font
menu is to call AppendResMenu('FONT') and then read out the menu
item text for each font. If you don't care about sorting, or WANT
the fonts whose names start with % (which are typically synthetic
ATM fonts) just look for all the 'FOND' and 'FONT' resources in
the system heap. You want to make sure to SetResLoad to false so
you don't actually load any fonts by mistake (japanese fonts can
be 5-10M in size, so you don't want to be loading them by accident)

Erik, here's a generic snippet to translate the return value of GetKeys()
into a workable array of booleans.  This took me a few hours to figure,
back when I started with the Mac.  You could alter it to just check for
the keys you're interested in - but this is so fast on a 6100 that in my
games you have to hope it doesn't register three times through the main
loop.  Included is a diagram of how the KeyMap is encoded into the four
unsigned longs you're seeing.

void doKeyCheck()
{
long     x,y;
unsigned long     z;
KeyMap            theKeys;
Boolean           theKeysDown[128];

      y = 0;
      GetKeys(theKeys);

      for(z = 0; z < 4; z++)
      {
         for(x = 16777216; x <= 2147483648 && x > 0; x = x*2)
         {
            if(theKeys[z] & x)
            {
               theKeysDown[y] = 1;
            }
            y++;
         }
         for(x = 65536; x <= 8388608; x = x*2)
         {
            if(theKeys[z] & x)
            {
               theKeysDown[y] = 1;
            }
            y++;
         }
         for(x = 256; x <= 32768; x = x*2)
         {
            if(theKeys[z] & x)
            {
               theKeysDown[y] = 1;
            }
            y++;
         }
         for(x = 1; x <= 128; x = x*2)
         {

So how does this work if the poor user has not only a keyboard but also a
joystick that generates keys?
KeyMap does contain only the status of the device that was the last to
report a change. If you press and hold something on one device and then
press some key on another device you only have the key active on the
second device in KeyMap.

   Woah there. There's a much easier way. It looks something like:

Boolean KeyIsDown(KeyMap map, unsigned char key)
{
   return ((unsigned char*)map)[key >> 3] >> (key & 7);
}

Just a note for Pascal users: this problem *does not exist* in Pascal!
The KeyMap is a packed array of Booleans, so we can just look up the
key we want. C has no packed arrays (and really no true Booleans either
for that matter) so in C it has to be done the other way.

var km: KeyMap;

GetKeys(km);

if km[someKeyCode] then ...

Just so you don't get lost in a mess of BAnd, BSL etc for no reason.

At the moment, I don't believe there are any yet, but I may be wrong.
Maybe EveryWare (the Butler SQL people) will be the first?

The book _Tricks of the Java Programming Gurus_ by Vanderberg, et al., has
a chapter on JDBC.  It's not huge, but it's a good start.  It has sample
code, and talks about some of the details about database programming in
general, not just the JDBC API.

   Depends upon what Mac you want to do this on.  I expect that Spectre
   was written entirely in 68k assembly and probably implemented some form
   of a delta rendering algorithm for more efficiency.  It ran great on my
   old LC 020.  Writting a 3D game for the 68k series is quite an
   undertaking, esspecialy if you want to get more complicated than
   Spectre.  Hornet and A-10 are about as detailed as you can get on a
   68k, and even those engines require quite abit of assembly optimzation
   and sophisticated rendering algorithms to get as much speed as they get.

   You could probably get away writting a maze-like 3D game that's above the
   level of Spectre on an 040 25Mhz or better Mac using standard rendering
   technqiues and no assembly.  That's just a guess ofcourse.  I've never
   programmed graphics for the 68k's.

   The PowerPC is my forte...
   The PPC can handle alot without any special assembly optimizations.
   I've written a nice 3D polygonal engine that does Gouraud shading
   and texture mapping for the PPC without any assembly at all... infact,
   it's mostly floating point code.  There's no way you could use floating
   point in such great quatities on any 68k Mac and get away with it...
   you'd have to use an integer fixed-point format to emulate floating
   point numbers.

   So, to answer your question... yes and no.  Yes, fast Macs
   like the 040's and PPC's could do it even if your not the worlds
   greatest programmer.  No, slower Macs couldn't do it unless you're
   very experienced and know how to optimize.

   If you need any help in the 3D algorithm department, I'd be happy to
   answer any questions you have. :)

OK, I have several questions <g>.  Games like Hornet/A-10 seem to use a
"delta"  drawing algorithm.  They only draw the portions of polygons that
have changed from the last screen, thereby greatly minimizing VRAM writes.
You can see this by doing a force quit and cancelling--the game will only
draw the polygons which have moved, leaving the rest white. This type of
engine makes sense when much of the screen stays the same from frame to
frame (i.e. mostly constant shaded polygons), but does not work well when
most of the pixels change (i.e. full screen texture mapping) since you
have the unnecesary overhead of determining which pixels change.  Am I
correct?  What are the general steps of such an algorithm, assuming you
are given a forest of BSP trees?

You can still gain some advantage by using it to prevent overdraw and by
using it for flat-shaded areas in an otherwise textured game (if you mix
textures and flat polygons).

>What are the general steps of such an algorithm, assuming you
>are given a forest of BSP trees?

You can do it on 2D polygons, if you want. Assign codes to colors (A-10
uses 64 colors and leaves 2 bits for HUD graphics overlays) and scan convert
into a span list. You then compare it with the span list from the displayed
frame and draw the differences.

A-10 pays a price for the HUD, because it has to exclusive or the changes
into the frame buffer, so it has to read and write video memory to make
the modifications. (They may do it differently, if there is no HUD overlay
displayed.)

Avara uses virtual colors, so that you can have thousands of colors and
even use patterns to generate more colors in modes that normally have only
256 colors or less. The approach means that it can work correctly even
when the color depth changes in the middle of an animation or when the
animation spans multiple screens. It also means that it needs an additional
table lookup before drawing each span, but the cost of doing that is very
small.

The critical part of drawing just the differences is in scan converting the
polygon edges into the span lists. The main difficulty is that the algorithms
tend to get slow very quickly as the number of overlapping polygons increase.
For a maze game, you would then want to minimize the number of overlapping
polygons that are fed to the scan converter. I was able to improve on the
well known pubished scan conversion algorithms by quite a bit, but it's still
the major CPU bottleneck in Avara for certain types of scenes.

In a Descent/Doom/Marathon/Quake like environment, you would want to cull
as many polygons as is possible before they reach the final stages of the
pipeline. The use of visibility "portals" works well for this. Quake uses
bitmaps to indicate what surfaces are potentially visible from a subspace.

Ahh, I see.  Thanks!  I was thinking of doing it differently:  Each
polygon stores a set of "previous" screen coordinates.  First you make a
list of polygons in front to back order, using the BSP trees.  You
traverse each polygon from back to front.  If the coordinates change, you
fill in the newly covered areas with the polygon's color.  For the pixels
which are "uncovered", you cast a ray through the polygon list, starting
with the one ofter this polygon.

I guess I'll have to try both methods and see which works well for my data.

I lost you here.  Can you explain?  What is a portal, and what do these
bitmaps represent?

The _Black Art_ book is a fine flatshaded polygon renderer but the
chapters on texturemapping is a bit lame. For texturemapped polys try
Andrew Meggs excellent Screaming Cabala texturemapper with unbeatable
speed (and it's free too) or take a look at 3DGM GameMachine; a
texturemapping 6DOF commercial library with DXF import, collision
detection (which is actually harder to do fast than texturemapping
itself), fog, animated texmaps and lots of help for the gameprogrammer.
Only problem is that it's expensive.

Why should enginesw per se suck? A 3D engine is simply {;)} a buzzword for
someones 3D routines.

It is impressive, but poorly documented and as far as I can tell, a
programming interface that is somewhere betwen awkward and hopeless.
Feel free to argue against me, but has anyone made any hacks with it
where you have put in your own shapes?

I don't find $200 particularly shocking for a lib like this. It is pretty
good, fairly well documented and not too hard to use, at least until you
want to get textures in. Getting the right texture on each polygon is rather
tedious. And it is fast.

Subject: How to determine volume-directory of current application?
Date: 20 Sep 1996 20:44:03 GMT
Organization: TWICS - Tokyo Public Access Internet

I need to be able to find the volume and directory IDs of the current
application, without necessarily knowing the name of the application or
how it was launched. Is there a good way to do this? The background is
that I want to store some application-specific index files and data
structures in a folder that will be inside the same folder that contains
the application. I could just use a relative path name, but IM leaves me
wondering if that will always work, especially in cases where the user
may have double-clicked on a document that is stored somewhere else, or
where the application is responding to an Apple Event.

I've noticed that some applications, like Eudora, Netscape, and Nuntius,
place folders for this kind of stuff inside the Preferences folder, but
that doesn't seem like a very clean solution.

If you have any ideas, I'd appreciate a note, either by E-mail or here in
this group. Thanks!

Tim

Is there any way to do this without need to hardcode the path?  In other
words I want the remote Mac to do the work of locating the application
just like when on my local Mac if I double click a ClarisWorks document
the Mac opens the ClarisWorks application - it knows where the application
is and launches it.

On a related note, why is that AppleScripts require you to manually find
the application you specify in a tell statement?  Similar to the
ClarisWorks document example, it seems that it ought to be able to figure
this out on its own, no?

instead of 'on', I never can remember
   open file "TheApp" of folder "Applications" of disk "The Disk"

    open application file id "R*ch"

I've finally recieved the MacMkLinux DR2 CD, installed it on my computer,
and when I try to boot it freezes.  It starts out fine, gets to the
MkLinux splash where it gives you the option of booting MacOS or Linux.
If I boot MacOS it's fine.  If I boot Linux, the whole computer freezes.
The mouse doesn't move any more, I can't hear the hard drive spinning.
ctrl-apple-reset still works.

I have a Power100, an SVGA monitor plugged into the SVGA port of the video
card that came with my computer, 40 megs RAM.  I have 64megs swap, 300
megs /root, and 400 megs /usr.

My MacOS drive has SCSI ID 0, and my MkLinux drive has SCSI ID 1.  The
MacOS drive is the currently selected boot drive.  'There are five
partitions total on my Linux drive, I have nothing plugged into the SCSI
port, I have a CD-ROM drive at SCSI ID 3.  And I'm plugged into the school
ethernet, but I haven't gotten as far as setnet yet.

What am I doing wrong?

I haven't been following MkLinux much lately since I just upgraded to a
PCI machine that MkLinux doesn't support, but...

* make sure you use the proper partition numbering scheme (MkLinux and
the MacOS, including the Mac SCSI utility you used to partition the
MkLinux drive, use different numbering schemes.  One of them starts
numbering with 0, the other starts with 1.  This used to be in the
MkLinux docs).

* MkLinux video support has been rather spotty for nonstandard video.
Macs with AV cards were not supported at all for awhile.  Perhaps the
VGA port on Power Computing machines is not supported.

You might consider subscribing to MkLinux mailing lists and asking
about your problems there.  See

I don't think MB will be of much use to you here; if it's an application,
you should be able to tell when it crashes; if it's an extension or system
problem, diagnosing it with MB will require a very thorough knowledge of
Mac assembly.

I'd recommend Cassady&Greene's Conflict Catcher software. If you really
have some reproducible evil in your combination of software, it will be
able to figure it out.

Hi, You should first try some easier things. Upgrade to 7.5.5 if you haven't done so. Zap your PRAM 3-4 times. Use Extensions Manage=
r to turn off half your non-essential extensions, reboot and see if the problem persists. If not, you have an extension conflict in =
the remaining half. Turn on half of these, reboot and so on. Have you rebuilt your desktop in the past few months? If the above is n=

I've been using Apple's "MacsBug Reference and Debugging Guide", though I
must admit I would have loved to see a book that is to Macsbug what Scott
Knaster's books are to the Mac.
  Apple's "MacsBug Reference and Debugging Guide" certainly covers Macsbug
well for conventional use. However:

 * Quite a number of new features have been added to Macsbug (notably
   PowerPC support) since this book was published. While Macsbug's
   inbuilt 'Help' mechanism is always up to date, this is hardly a nice
   way to welcome anyone into the Mac-debugging world. An up-to-date
   version of Apple's Reference book is certainly in place if not
   overdue.

 * It is usually _not_ very long before you hit Macsbug's limits,
   (or at least before they come into sight) so if any of the non-Apple
   books (e.g. Otmer and Strauss "Debugging Mac Software with
   Macsbug") have "insiders' secrets" I would certainly give them a
   browse for possible extension of Macsbug fundamental capabilities.

I'd use conventional methods of figuring crashes out, i.e. conflict isolation
and/or installation of new system software before plunging into
the Assembly jungle of programs you don't have the source for.

If you nontheless want to go about it the low-level way, you can put
Macsbug in the System Folder anyway, and keep some record of WHere the
crashes occur, to see whether there's any rule in them at all, then take
it from there.
  For example, you can write a macro to log where a crash occured,
register state, and the stack call-chain, then put it in the prefs to make
it permanent. e.g.:

  mc myMacroName 'log myPathName; WH; TD; SC; log'

You may also want to have traps recording on, then play it back (ATP) into
the log.

There's a way of making a macro execute each time the debugger is
dropped into, but the manual's back home + I can't remember exactly
how (but I guess it would be some messing with the prefs file).

I guess that's it 4 now. Hope this helps.

I don't think MB will be of much use to you here; if it's an application,
you should be able to tell when it crashes; if it's an extension or system
problem, diagnosing it with MB will require a very thorough knowledge of
Mac assembly.

I'd recommend Cassady&Greene's Conflict Catcher software. If you really
have some reproducible evil in your combination of software, it will be
able to figure it out.

Apple has a little text file with MB, I believe, which describes the
basics. Just for the es (quit current app) and rs (restart) commands,
everyone should have it installed. But using it seriously is basically a

I would like to open a control panel from my application. I have an FSSpec
for the control panel. I have tried LaunchApplication() but that did not
work (which, sadly, makes sense). I've also tried sending 'odoc' and
'oapp' AppleEvents to the Finder, all to no avail.

Can anyone point me to some code that does this or offer a simple

The Finder doesn't take ODOC events. Instead, it takes OpenSelection
events. You create the appleevent, stick on an alias/FSSpec to a
folder containing the items to be opened (in this case the control
panels folder) and then stick on the list of items to be opened.

Greg -

Well, if you're drawing a PICT that's a Resource, do this :

#include <QuickDraw.h>

void
DrawPICTFromResource(ResIDT inResourceID, int x, int y)
{
    Rect        pictureBounds;
    PicHandle    hPic;

    hPic = ::GetPicture(inResourceID);


    if(hPic) {

        // set the rect to the same as that of the picture. You can
        // scale here if you like
        pictureBounds = (*hPic)->picFrame;

        ::DrawPicture(hPic, &pictureBounds);

    }

    // don't forget to lose that memory
    ::ReleaseResource((Handle) hPic);
}



I think that's about right. If you want to draw from a file, use the
DrawPictureFile() function.

Best Regards,
Russ.

The MacTech CD ROM is useful for me.  It has all the managers/function
calls in a very fast search engine that is hyperlinked all over the
place.  It has saved me days of time searching for answers to questions or
prototypes for toolbox calls.

It also has every issue for the past 11 years of MacTech magazine,
searchable by topic/date/author/etc.  It is worth every penny!

Yes, it's published by Addison-Wesley, and costs about $100. You can buy

     The MacTech CD is very kool and it's a superset of Think Reference
        using the Think Reference engine to access all the toolbox
        functions included in the TR data bases as well as the
        MT journal articles for a more detailed discussion.  I'm
        kind of biased--but I tend to agree with Matt that it's
        worth every penny.  More details on it are available at:

              <http://web.xplain.com/mactech.com/cdrom/>

     But to answer your original question: Yes the NIM is available
       on CD Rom--it's also DL'able from Apple's Web site.  NIM
       is useful for a different reason that the MacTech CD (IMHO).
       The MT CD gives you a brief overview of syntax and usage of
       toolbox functions (as well as examples), and the articles
       give you more detailed discussion of concepts.  But NIM gives
       you exhaustive detail on the functions.  Sometimes you need
       that, and it's useful to have access to the NIM.

Rumor is that they have a DLL version of GX that you will be able to
bundle with your Apps individually - though it will likely be installed as
part of the system.

There are also some advocates for Apple to include it with their QuickTime
engine - or to include it as a cross platform graphics rendering engine
for internet.

The newer GX is smaller, faster, and feeds the pets ;-)

Check out the Electrifier plug-in at http://www.electrifier.com

some of us are hoping that Apple will commit to sharing GX with the rest of
the world as a new paradigm for Internet graphics that I've nick-named
"Apple Internet Graphics."

A.I.G. ala Electrifier allows for extremely sophisticated graphics that
download in as little as 1% of the time that the equivalent using standard
bit-mapped graphics would take.

A.I.G. could use a file format that would replace HTML and allow
professional-level DTP to take place on the Internet.

A.I.G., with a trivial extension to what GX already offers, could allow for
animated fonts, shapes, textures, etc., that wouldn't take but a second or
so longer to download than their static equivalent (you'd just embed a
script/Java applet in the shape that would execute during idle time in the
browser).

A.I.G. would allow shapes/texts/plug-ins to *talk* to each other and allow
user interaction as well.

A.I.G. could become the alternative high-end standard for Java.

A.I.G. has generated lots of public flames and lots of private kudos for
moi on the semper.fi mailing list.

A.I.G. may or may not happen. I understand that all the Apple bigwigs have
debated the idea since I first introduced it (actually, I suspect that they
came up with it on their own some time ago but that internal politics
pretty much killed it until I got noisy).

A.I.G., if done right, would be the most spectacular marketing action ever
done by Apple: it would automatically make it a *Major* player on the
Internet.

Something like that.

Can a format be successful on the Internet/intranet when <10% of the
clients extant can use the format?  Probably not, because few will find
it rewarding to develop tools for, or create content for, that format.
Apple is not the most credible or eager provider of cross-platform
software.  Should it even try to be?  If GX were completely unique in
its capabilities, with nothing similar on the horizon, that would be one
thing.  But GX faces a tough competitor as Adobe drives its imaging
model into browser technology ("Bravo").  Finally, what about the
business case?  If Apple were to spend the time and money to make
QuickDraw GX a cross-platform module (which it could certainly do, akin
to QuickTime), would this materially improve revenue or profitability?
Probably not.

The problem with many Apple technologies, GX included, is that while
wonderful on their own, they seem crafted in a vacuum, without reference
to what other companies are doing.  Designing with a "build a neato
capability and they will come" mentality, Apple is left with a whole
grab-bag of technologies, many of which partially overlap products with
a better shot at life, and most of which are insufficiently compelling
to marshall broad development resources.

If you buy this line of reasoning--mac.advocates.who.never.say.die, of
course, will not--the problem is worse than poor marketing.  It's poor
economics.  Thereby hangs the tale.

True, but *I* have been advocating that Apple make GX available for anyone
to use via an OpenDoc/Cyberdog (ODF?) combo: anyone that is willing to port
OpenDoc/Cyberdog(/ODF?) to their own OS can license GX for the price of
doing the port themselves. -this includes Microsoft, IBM, Sun, and any
Linux provider. If Apple does the port, they can license it as they do
other such services cross-platform.

Ever hear of QuickTime players? And yes, in the age of the platform-neutral
(at least until MS gets its way) Internet, Apple has to be a "most credible
or eager provider of cross-platform software" in order to survive.

If GX were completely unique in

Bravo is based on the Illustrator/Acrobat engine. I suspect that it isn't
as pretty as GX, although of course, we haven't seen it yet, have we? GX
has 5 programmers manuals, including 2 that would be used by A.I.G.
programmers. They've been around for years. While the full engine used
internally by Adobe has been around for years, where's the shipping
products/plug-ins based on Bravo?

Go to http://www.electrifier.com for a plug-in AND a free middle-level
drawing tool to produce content for the plug-in using GX. I've checked
Adobe's site several times. Not only is there only one "major" paper (2-3
pages long) about Bravo at their site, but I've yet to see a time-table for
the release of any Bravo-based plug-ins and/or Bravo-producing editors.

 Finally, what about the

All these cross-platform solutions are *marketing* strategies. Both to the
end-user and to the developer. GX (AKA Apple Internet Graphics) made
cross-platform would be the same, only far more flamboyant than anything
that Apple or anyone else has done in the past.

While there are pleny of technologies from Apple that sorta fit your
description, I'm not sure that GX is one of them. Afterall, GX will be the
core graphics model of MacOS8 and probably of System 7.8/9.

Also, consider: GX is object-based and designed to be easily extensible,
both by Apple and by 3rd-parties. One of my proposed extensions to GX for
A.I.G. use would be to allow scripting/applets/something to be embedded in
shapes which can run during "idle time" and allow client-based animation
without pain.

How do you embed a script within a shape or group of shapes using Bravo,
which uses the PostScript model and whose API we have yet to see, BTW.

I suspect that Adobe would have to create a HUGE amount of glue to
accomplish this task, which *I* can do *right now* with a trivial addition
to the GX programming API within my own app.

How do you allow shapes to respond to messages from other shapes or from
embedded plug-ins using a PostScript model?

The same extension that allows shapes to respond to idle-time messages can
be used to respond to messages from other shapes, plug-ins, "cosmic"
applets, and user input (mouse clicks, etc).

Care to rewrite the parser for Acrobat to accomplish this?

*I* can do this RIGHT NOW with GX because of the original design.


GX is FAR superior in every way that counts on the Internet compared to
what I understand Bravo to be.

For instance, Bravo is touted as allowing "light-weight" DTP applets. GX
would allow LightningDraw-level (a $200 package, I believe) applets to be
used with Java supplying the GUI glue and GX supplying the API since that
is the basic paradigm of LightningDraw or so I understand.

If you want to characterize LightningDraw as "lightweight," feel free.


GX, recast as a cross-platform "Apple Internet Graphics" API would be a
Very Good Thing for Apple.

I'm still hopeful that Apple recognizes this.

Hi!

Can anybody explain to me how I (in C) can make a struct of float arrays,
where the array size is dependent on other variabels? The code below does
not work, and I can't really figure out how to make it work. Later on,
I'll need to make the array sizes from a dialog, so I'm trying to
understand how to define a struct after main() has begun to execute.


CODE:
- ---------

#include <stdio.h>
#include <stdlib.h>
#include <sound.h>
#include <SIOUX.h>
#include <ctype.h>
#include <string.h>
#include <unistd.h>

#define     kMaxX       16
#define     kMaxY       16
#define     kStepSize   16
#define     kZVar       16
#define     kXYVar      16

int   gMaxX=kMaxX;
int   gMaxY=kMaxY;
int   gStepSize=kStepSize;
int   gZVar=kZVar;
int   gXYVar=kXYVar;
int   gtheSize = (gMaxX * gMaxY);   /* Not Working - I wonder why? */

/***********************/
/* Struct Declarations */
/***********************/
struct XYZ
{
   float X[ gtheSize ];
   float Y[ gtheSize ];
   float Z[ gtheSize ];
};

- -----------
End CODE


These are the errors I get:

Error   : illegal constant expression
Gridmaker.c line 28   int gtheSize = (gMaxX * gMaxY);
Error   : illegal constant expression
Gridmaker.c line 35   float X[ gtheSize ];
Error   : illegal constant expression
Gridmaker.c line 36   float Y[ gtheSize ];
Error   : illegal constant expression

   Mikael,

   You can't do it this way.  A C compiler must know how large an array is
at compile-time, because standard C arrays are not dynamic. However, there
is an easy way to get around this.  Something like the code below should
work, although I haven't even tried to compile it.  You can certainly use
"malloc" instead of the Mac's NewPtr call to allocate memory, if you
wanted cross-platform code.
   The C compiler basically interprets a[i] as (*(a+i)), so it does care
whether you're dealing with a static array or a dynamically allocated
chunk of memory.
   Hope this helps,

                                 Eugene Kuznetsov

   XYZ.X = NewPtr(x);
   XYZ.Y = NewPtr(y);
   XYZ.Z = NewPtr(z);

   for (i = 0; i < x; i++) {
      XYZ.X[i] = 0.5;

I believe this question may have been answered here recently.  Basically,
you can't.  The compiler needs to know the size of the array at compile
time so that it can allocate enough memory.

I'd suggest requesting memory from the Memory Manager as an alternative,
though I do not know how to do this personally.

Sorry for the 'wrong' answer.  Many a time I've wanted to size an array
based on other variables.  But it can't be done.  (although if you do
manage, please share your secret with the rest of us!)

Right.

- -------------------------------------------
Here's how you can do it to get float or double vectors and matrices:

#define real float
/* Or if you want double, uncomment the line below and comment the one above
#define real double
*/

/* The routine FATAL_ERROR is one you can write to print out the warning
message and call exit(1) to terminate the program if there is a problem */

/* ---- Allocate a real vector --------------------------- */
real *VECTOR(long n)  {
   real *v;
   v=(real *)malloc((size_t) (n*sizeof(real)));
   if (!v)   {
      FATAL_ERROR("*VECTOR","  Allocation of memory for real array failed.");  }
   return v;
}

/* ---- Free a real vector ---------------------------------
   Remember, you MUST free memory when you are done with it.
   That means _before_ you exit a function that allocated the memory
   and you lose the pointer to it.  Then the memory is "tied up,"
   but unaccessible to you.  Bad news. */
void free_VECTOR(real *v)  {
   free((char*) v);
}

/* ---- Allocate a real matrix ------------------------------------ */
real **MATRIX(long nrow, long ncol)  {
   long i;
   real **m;
   /* allocate pointers to rows */
   m=(real **) malloc((size_t)(nrow*sizeof(real*)));
   if (!m) {
      FATAL_ERROR("**MATRIX","  Allocation of memory for rows of real
array failed.");  }
   /* allocate rows and set pointers to them */
   m[0]=(real *) malloc((size_t)(nrow*ncol*sizeof(real)));
   if (!m[0]) {
      FATAL_ERROR("**MATRIX","  Allocation of memory for cols of real
array failed.");  }

   for(i=1;i<nrow;i++) m[i]=m[i-1]+ncol;

   /* return pointer to array of pointers to rows */
   return m;
}
/* ---- Free a real matrix ---------------------------------*/
void free_MATRIX(real **m)  {
   free((char*) (m[0]));
   free((char*) (m));
}

- -------------------------------------------
Here's how you can do it to get integer vectors:


/*  ---- Allocate memory for int array --------------------------------------*/
int *iVECTOR(int n)  {
   int *ptr;
   ptr= (int *)malloc((size_t) (n*sizeof(int)));
   if (!ptr)  {
      FATAL_ERROR("*iVECTOR","  Allocation of memory for integer array
failed.");  }
   return ptr;
}

/*  ---- Free memory for int array ----------------------------------------*/
void free_iVECTOR(int* m)  {
   free((char*) m);
}

   -------------------------------------------------------
Typical usage:

/* A function that allocates a variable number of elements, calculates something
and then cleans up after itself. Remember to define real as float or
double, depending on which you want. */

real func(int n)  {
   int i;
   real *vec;
   real result;

   vec=VECTOR(n);  /* Make a 1D array of "reals", a vector */

   /* calculate some stuff here and get result...for example:  */
   result=0.0;
   for (i=0; i<n; i++)  {
      vec[i]=(real)(i*i);
      result +=vec[i]*vec[i];  }

   free_VECTOR(vec);  /* Free that memory. Very important before returning! */
   return result;
}

- ------------------------------------
I hope that helps (I did not see your original post, sorry).

Smalltalk is not a language that is accessible from CodeWarrior.  Besides
the economics factor (engineering costs for MW would be greater than
revenus on this one), Smalltalk requires a very specialised "shell" which
acts more like a sub-Operating System than an IDE.

SmallTalk on the Mac is best acheived (so I'm told, since I've not used it
myself) through Quasar Knowledge Systems' SmallTalkAgents ([e-mail],
800 296-1339).  They probably have educational discounts (though I'm not
sure).

I don't have your version, but an earlier one. It appears to me that
MacTraps contains the library you desire (I saw a CPstr.lib included in
it). I'm new to C++ but have done a lot with Symantec C, so I just did
a lot of Mac-ish point and clicking to find this info.

I was impressed when I played with this version to find that I could
do grep searches on the individual libraries like CPlusLib & ANSI++ after
double clicking them from the project window and opening a new window
for these. The search probably worked because the sources were identified.
Anyway I did this with the Bullseye++ Demo, but didn't find CtoPstr there
and when I added  a simple use of it to the main program I got the
link error as expected. Then I opened some other demos to try same.
When I came to the @1.pi project in ProjectModels/MacApplicationProjects
folder I opened the project and when I double-clicked the MacTraps
entry I saw CPstr.lib. Unfortunately grep searching was inactive here
(not source entries) so I placed the CtoPstr call in the main program
and was able to link. So this is how I answered this question.

I should say that I began by opening Think Reference and searching for
CtoPstr and saw many entries in the guides. This did not help me but I
did look at the sample codes in each use example to see what .h files
were included for hints. None the less, you should have a copy of
Think Reference. I purchased mine separately... but I think Sym C++ may
include it.

An old trick I used with the first Think C environment to be able to
do grep searches in all the .h files was to create a project called
AllDotH and included every .h file that I could find which came with
the system. The main program was a simple do nothing stub. It was
great for finding which .h file a particular function was in and
hence which library was needed. Today however an ANSI lib is used
rather than many individual ones back then so this trick may not be
as useful now. Also, doing this in C++ may be unwieldy. And finally,
given my pleasant findings with SymC++  (i.e., being able to do
multi-file grep searches on the libraries) this old trick may be
obsolete. But I give it to you just the same... old trick have a

I'm sure they do. My books are at the office so if you don't figure
this out then email me at [e-mail] and I will look up
a phone number. I start by looking at one of my Symantec Manuals to
find the tech support number. Often I get an old manual (it is usually
more prominent in those) and the number has likely changed... but it
is also as likely that I scratched in the new number so I probably have
it handy.

I don't have your version, but an earlier one. It appears to me that
MacTraps contains the library you desire (I saw a CPstr.lib included in
it). I'm new to C++ but have done a lot with Symantec C, so I just did
a lot of Mac-ish point and clicking to find this info.

I was impressed when I played with this version to find that I could
do grep searches on the individual libraries like CPlusLib & ANSI++ after
double clicking them from the project window and opening a new window
for these. The search probably worked because the sources were identified.

[snip]

CtoPstr() and PtoCstr() have changed. They are now defined as c2pstr() and
p2cstr() in the file, "Strings.h", and their declarations are in
PPCRuntime.o or Runtime.o in the 68k version.

Thanks Alex.  I was unclear on whether the VM enhancements applied to the
68k code; I see in the Tech Note 1069 that indeed the 68k VM has been
rewritten too.

On my Quadra 605 with 8 megs real ram, the new 7.5.5 VM _seems_ the perform
as well as RD did for me under 7.5.3.  YMMV, of course.

Actually, VM wasn't completely rewritten by any means -- Jim Gochee,
working for Apple's Performance Engineering Group, identified some
behaviors in VM that caused performance problems and I fixed those
problems. The performance increase is much more noticable on Power
Macintosh systems, but 68K systems will still benefit.

I also fixed all of the outstanding bugs against VM in our bug database,
so VM should be more stable. We've found a few programs that still don't
work with VM on, but that usually turns out to be a problem with that
program, not VM. For example, versions of the MPW shell prior to v3.4.2b2
(on E.T.O #21) were installing a Time Manager task more times than they
were removing the same task when ScreenUpdateDelay is changed from its
default value. While that will cause problems even with VM off, turning VM
on made the problem much more noticable because the table where VM stores
deferred user tasks overflowed because the calls were not balanced.

Warden -

Is the Add... dialog window filtering out the .rsrc files or do they just
not appear properly in the project after you've Added them? Try adding
them to a brand new project just to make sure there no funky corruption
that's messing up your current project.

It may be that you're running into an artifact of the generation gap
between v5.0.4, which was released in 1989 and the machine/OS and possibly
whatever resource editor you're using to create your resource files.

I highly recommend that you update the THINK C version that you have to at
least v7.0.5 or better yet v8r5, if you have a Power Mac.

This is definitely an "artifact problem". THINK C 5.0.4 did not let you
load resource files using the Add... menu item. What you need to do is
name your resource file the exact same thing as your project plus .rsrc.
So if your project is named dummy.º, you would name the resource file
dummy.º.rsrc. This is the only way to add resource files to THINK C 5.0.4

THINK C finally broke for me when I got a PowerMac; it is not compatible
with the Modern Memory Manager. I considered upgrading to Symantec C++,
but I think I'll be getting CodeWarrior instead. Metrowerks' academic
pricing can't be beat, and CodeWarrior will let you compile for a number
of different platforms as well.

Anyway, I hope this helps.

Hi,

I'm using the Time Manager to wake up my background app periodically.  But
there are a few problems.

I'm having some trouble setting the wait time.  I want it to wait 15mins, so
as there are 1000 millisecs in a sec and 60 secs in a min I set it to
60000*15 or 900000.  But, it seems to execute every couple of minutes.
What am I doing wrong? I use InsXtime and PrimeTime.

Also, there is a problem with RmvTime.  I call it just before my program quits,
so that it should be removed on Shut Down.  My program runs from startup to
shut down.  However, when I try to shut down I get an error that the
application unknown wouldn't quit.  When I comment out RmvTime it quits fine.

What am I doing wrong?

Thanks in advance,
Giles Alexander

Make sure you are either compiling with 4-byte ints, or that you specify
the time as 900000L (long integer constant).

Could it be that you're storing the 900000 figure in a datatype that's

 I havn't got much in the way of good documentation for QuickDraw so I don't

Try initializing the ToolBox first   ;-)

Seriously, there is enough sample code out there that you should be
able to find some that does almost everything you want to do. Find
some good Mac programming resources on the web (I'll leave it to you
to find them. [Hint: search engines]), and peruse.

Also, Apple have large amounts of documentation online, and on
the shelves in bookstores. Use it.

  Apple's Developer CD's usually contain the fantastic 'TubeTest'
starter program. It instantiates a Window and draws two 'eyes' of
concentric circles on it. You can make the eyes hypnotic by running a
simple palette animation.

Anyway, this is informal, well documented (commented) and the perfect
thing for starting you off. If you can't find it (I may have wrongly
named it), eMail me and I'll send you my CodeWarrior copy.

Don't forget that all of Inside Macintosh is available online as well. Go
to <http://devworld.apple.com/dev/insidemac.shtml> and check it out.

Here's a tiny, crude snippet that will open a window and draw a couple
rectangles in it, if you prefer the quick and dirty approach. Please note
that this is NOT a complete Macintosh application, simply a demo of
NewCWindow and a couple drawing routines.

main()
{
   Rect     myRect;
   WindowPtr   myWindowPtr;

   // Init Mac toolbox
   FlushEvents (everyEvent - diskMask, 0 );
   MaxApplZone();
   InitGraf (&qd.thePort);
   InitFonts ();
   InitWindows ();
   InitMenus ();
   TEInit ();
   InitDialogs (nil);
   InitCursor ();

    // Create a 100 by 100 window, 20 pixels from the left of
    // the main screen, and 50 pixels from the top
    SetRect(&myRect, 20, 50, 120, 150);
    myWindowPtr = NewCWindow(
               nil,           // let system allocate storage space
               &myRect,       // size of window in global coordinates
               "\pA Window",     // window title
               true,          // window is visible
               documentProc,     // regular document window
               (WindowPtr)(-1),  // Put it in front of all other windows
               false,            // no close box, please
               0L );          // refcon is zero

    // Get ready to draw a rectangle
    SetRect(&myRect, 10, 10, 60, 60);
    SetPort(myWindowPtr); // not really necessary here, but a good habit
    ForeColor(blackColor);

    // Draw it
    PaintRect(&myRect);

    // Offset the rectangle and draw it again in a different color
    OffsetRect(&myRect, 30, 30);
    ForeColor(redColor);
    PaintRect(&myRect);

    // Wait for a mouse click, then quit
    while(!Button())
      ;

    // clean up

I am planning on buying a new PowerMac 7600/132 to replace my dieing
Mac IIci. The IIci has two programmers switches on the front of the unit.
One lets me drop down into my debugger the other reset the computer. I
do not see these two switches on the 7600 unit. Did I miss something.

How do you drop down into MacBug? How do you reset the CPU?

Thanks,

      There's some funny combination of several keys you have to press
all at once, but I can never remember what it is.  It's one of those
"oral tradition" Mac things, like understanding off-key startup chimes.

For interrupt (i.e. - programmer's switch):
On most contemporary Macs, press and hold the "command" (Apple) key
then press the Power button (the one in the upper right with a triangle
on it).

For reset:
Same as above, but press and hold command and Control, then Power.
These are much more convenient for debugging than the little buttons on
the box used to be.

If the machine gets into a really screwed up state, sometimes the above
will not work. Then you use the old-fashioned method: pull the plug :-)
(or turn it off, then on again).

Lo, come gather in the circle to learn the secret of dropping into MacsBug
on many new Macintoshes,... :^)

No, seriously.  You can kick into the debugger by hitting cmd-powerkey.
This'll give you that oh-so-familiar (assuming you have it installed, of
course) screen-o-hex that you know and love.

=======================================================================
MultiQuest Announces S-CASE 3.0 for Macintosh
With Unified Modeling Language Support & Reverse Engineering
=======================================================================

Schaumburg, IL (September 23, 1996) - MultiQuest announced today the
release of S-CASE 3.0 for Macintosh. This new version satisfies the
demand for Unified Modeling Language tools brought about by the
increasing popularity of this new method. The Unified Modeling
Language, proposed by Grady Booch, Ivar Jacobson and Jim Rumbaugh
represents the unification of the Booch, Objectory and OMT methods.
S-CASE 3.0 enables analysts, designers and engineers to start using
this method right away, utilizing its potential to create simpler,
cleaner and more expressive models.

S-CASE 3.0 also introduces scripted access to its metamodel. Users can
now extract model elements using Tcl scripts, and output them in
whatever format they wish, such as C++, Java, Smalltalk, SQL or
customized reports. In fact, the built in C++ code generator is written
entirely in Tcl, enabling users to customize the output to their coding
standards.

"The possibility to reach the model from scripts opens for instant
documentation of our classes and for adapting the code generation
process to our internal conventions," said Anders Igelstroem, Project
Manager at Innovativ Vision Image Systems.

S-CASE 3.0 provides C++ reverse engineering capability which is
extremely fast and easy to use. It also allows automatic layout of
parsed models for quick visualization and comprehension. Reverse
engineered models can be integrated with existing applications
or new projects.

S-CASE 3.0 promotes design reuse by introducing the concept of
packages. Packages encapsulate all the elements needed for reuse.
Users can create new models from "off-the-shelf" packages.

"S-CASE 3.0 provides us with tremendous flexibility in terms of how
we go about refining and extending a design", said Frank Alviani,
Senior Technical Coordinator at UOP. "It gives us the critical ability
to reuse designs, which is where the ultimate payoff for reusability
really lies."

Available immediately, S-CASE 3.0 for Macintosh lists at $495.
A save-limited evaluation version can be downloaded from
http://www.multiquest.com.

Founded in 1989, MultiQuest Corporation offers innovative tools and
services to software developers worldwide. The company's mission is
to consistently increase the productivity of software engineering
teams by providing superior tools to analyze, design and implement
complex software systems. For further information please call

Subject: [Q] Creating fog in QD3D
Date: 16 Sep 1996 13:51:01 GMT
Organization: VR

I am trying to create the effect of fog or haze that one sees as objects
get farther away from the view point.  In OpenGL this is created by
defining a "fog factor" which the renderer applies, based on an object's
distance from the eye point, when calculating the color of a pixel.  Is
there a way to do the same thing in QD3D?

Thanks in advance for your help.

Fog and clouds are not featured in the current QD3D, so you'll have to
a. wait for them to be added
b. come up with your own

Perhaps someone with more practical experience with QD3D can suggest some
good tricks for you, but I recommend looking up the techniques in a
Computer Graphics Bible.

   Real "fog" can not easily be rendered unless you scan-convert and
   render the polygons your self.  Because fog density is a factor of
   distance, the Z coordinate of polygons should be interpolated during
   scan-conversion to tell the scan-line renderer what amount of the
   "fog" color should be applied to each pixel.  For speed concerns, the
   fog colors should be stored in an array which stores all possible
   fog densities overlayed onto all possible colors.

   You could do some Fake fog by changing the color of individual
   polygons slightly as they move into the distance, but I really doubt
   it would look good.

Hi there!


I have an interesting problem. I'm writing a music program that lets you
change the size of your song on the fly. I decided the best way to do this
is to edit a text file. That way, I wouldn't have to worry about changing
the size of an array (which is hard) and running out of memory (okay,
okay, you could run out of disk space but it's more likely that someone
would have more disk space then memory).

To do this, I'd need to be able to access any point in a text file. That's
easy. But I also need to change part of a text file without changing the
entire thing.
I haven't found an IOStreams or stdio.h file that does this. So my question is:
how do you do it?

My program isn't too speed dependant so I don't need to worry about things
taken a little bit of time. (But I can't use code that takes seconds to
compute. It adds up and becomes annoying to the user).

Any help about how to do this would be great.

Hi Brian, It's hard to answer you without knowing a little bit more. Have you used fopen("foo.text","w"); in your work before? You n=
eed to open the file ,use fscanf, use the feof, and use fclose. If you haven't used these before, I'll send some snippets. It may be=
 useful to number your lines in your text file as a reference, tho this may not be necessary.

Accutally, I was using C++ IOStreams to open the file. If you think
regular C code will work well, then feel free to send my some snippets.

Subject: [Q] ShutDwnPower mystery?
Date: Sat, 21 Sep 1996 20:36:29 -0500
Organization: Frontier Internet Rochester N.Y. (716)-777-SURF

I'm writing a simple password program, mainly to learn C, and everything
works fine except for one thing.

The way it works is that if an incorrect password is entered more than 3
times, the application saves the time and date of the intrusion attempt in
a resource, and then shuts off the machine's power with ShutDwnPower();.
While working on it, I've used ExitToShell() instead of ShutDwnPower() for
the obvious reason that I don't want to reboot my machine each time I test
it. The strange thing is that the built application works fine with the
call to ExitToShell--that is, it writes the resource of the intrusion
attempt, and then quits to the finder. When I build the application
substituting ShutDwn Power for ExitToShell, it shuts the power down,
allright, but it DOESN'T write to the application's resource file. Does
anyone know what's wrong?

            //ShutDwnPower();  //<-----uncomment this for application
            ExitToShell();
This works!

            ShutDwnPower();
This doesn't!!
This is absolutely the ONLY thing I changed!!

Your're not flushing the changed resource to disk. You'll want to call
UpdateResource and then flush the disk cache. I don't remember how to do
this. I would consider sending the finder an event telling it to shut doen
as sinply cutting the power isn't nice on the filesystem.

You say that you save the time and date of the intrusion attempt in a
resource- are you calling UpdateResFile on your app's resource fork after
doing the WriteResource? UpdateResFile forces a write to disk.

Normally you don't _have_ to call UpdateResFile, because the resource fork
is updated when your application closes. (even via ExitToShell). However
calling ShutDwnPower is pretty much like pulling the plug- you can't
expect the data to be written out beforehand.

It sounds like you forgot to close your resource file. ExitToShell does
that for you (if you forgot).

Perhaps you forgot to close your resource file after writing to it.  If
you haven't already, use CloseResFile() or UpdateResFile(), depending on
how you accessed the resource file.  If the application writes to it's own
resource file, UpdateResFile() is sufficient.  Otherwise, if you used
something like OpenResFile() to access an external resource file, then
CloseResFile() will do the trick.

I hope this helps.

Your're not flushing the changed resource to disk. You'll want to call
UpdateResource and then flush the disk cache. I don't remember how to do
this. I would consider sending the finder an event telling it to shut doen
as sinply cutting the power isn't nice on the filesystem.

You say that you save the time and date of the intrusion attempt in a
resource- are you calling UpdateResFile on your app's resource fork after
doing the WriteResource? UpdateResFile forces a write to disk.

Normally you don't _have_ to call UpdateResFile, because the resource fork
is updated when your application closes. (even via ExitToShell). However
calling ShutDwnPower is pretty much like pulling the plug- you can't
expect the data to be written out beforehand.

Subject: [Q] Smooth text scrolling in a Rect
Date: 24 Sep 96 10:22:08 -0500
Organization: Minnesota State University System

Hello,

For the next segment of a game I am currently working on, I need to create
a text box that scrolls text that is generated from the current battle.
This is a role playing type game and when the player/character encounters
a monster a "battle window" [a standard mac window without a title bar] opens.
In this battle window are buttons for the user to push (like "Attack"), two
areas for pictures of the character and for the monster, and an area that I
would like to contain randomly generated commentary on the battle. Such as,
"Sir Ralph swings at the orc, hitting him."

What is the best way to get text to scroll in this region, preferably smoothly?
My solution, which I haven't implemented yet, involves creating an offscreen
gWorld the same size as the region in the battle window. Sending the text via
DrawString() to the gWorld then CopyBits() back to the screen region. Before I
send the text to the gWorld I would have to have to copy within the gWorld
moving the text up. (So that there room for the new line of text.)

*Speed is unimportant since it is a turn based game.
*Coding in c.
*Using Codewarrior 9

Thanks, in advance, for any and all help.

Fellow Mac Programmer (who's just starting),

Better solution is to use an offscreen GWorld that's about one line taller
than your text window.  Draw your text into the 'bottom line' of the
offscreen GWorld, and then copybits the top part of the GWorld into your
screen region (that is, copybits the whole GWorld above the area you drew
your text into).. then (depending on whether you want the text to scroll
synchronously or asynchronously), lower the rectangle you use for your
offscreen CopyBits routine by one or two pixels, and CopyBits again.  And
again.  And again. (Either one immediately after the other, or with event
loops between them, if you want the scrolling asynchronous)  Continue
until the text is fully visible in your scrolling text area.  At this
time, move everything in the offscreen buffer up one text line
(ScrollRect() is probably the easiest way to do this, though CopyBits()
would work as well)...  repeat, when you need to enter another line of
text.

Hope this helps!

Hello, everybody,

I'm about to install a system extension, which should perform the
following action:
Whenever the user presses the mouse button in the upper right corner
of the screen a window should appear and disappear again when the
button is released.
I already wrote the function which works fine as stand-alone
application. Then I wrote a system extension which loads the
functions code into the system heap at startup time, but now arises
the following problem:
How can I tell the system, that this function (which shows the
window) has to be executed whenever the user presses the button in
the upper right corner of the screen?
Do I have to install a VBL-task?

Any help is appreciated. Thank You!

You'll need a JGNE filter. Check out Extension Shell by Dair Grant - it has
working examples in CW how to do this. It's fairly easy.
Also, don't forget that since you're in the INIT, your resource file is closed.
You'll need to store your res file's refNum in a global and when your code
executes open your resFile and load the resource (WIND , DLOG, whatever). Then
close your res file.

Subject: help with malloc() needed
Date: Fri, 20 Sep 1996 03:05:10 GMT

It's a very short program; here's the code:

____________________

#include <stdio.h>

struct node {
    char *name;
    char *id;
    int grade;
    struct node *left, *right;
};

main()
{
    struct node    *root;

    root = (struct node*)malloc( sizeof( struct node ) );
}

_____________________

that's it!  Why is it that I can't use malloc()?  When using the debugger
(I'm using Symantec 7.0), right after 'root' is declared, all of the
members of the record seem to have memory allocated correctly.  After the
call to malloc(), all of the members have "bus error" written next to
them.  Do I have to use some mac-specific Toolbox routine instead of
malloc()?  Or do I not have to call malloc at all, in which case, how
would I allocate memory for the 'left' and 'right' members of 'root' ?
(when I first declare 'root', the members 'left' and 'right' are
initialized with NULL values).  Help!!!!  I've had this problem with
malloc before; when I compile stuff with gcc at school, malloc() doesn't
give me any trouble (UNIX is the OS), but when I try to compile code that
contains malloc() on my mac, I get crashes and "bus errors".  AAHHHHH!!!!!

You need to get the correct prototype for malloc by including the correct
header file:

#include <stdlib.h>

Otherwise your code looks ok and malloc does work. If you turn the C++
compiler on you can use "new" and a little cleaner syntax for defining the
struct pointers.

I've seen SYS 5.0 out there at some of the university based shareware
sites, nothing older. Sys 3.0 is best suited for the 512k (Fat) Mac. The
only place I've seen it is for sale ($15.00) at Sun Remarketing.

Good luck,
