Tim,

The documentation indicates that the PATH will be searched for sstools.ini
if it isn't found in the current directory.  This no longer occurs.  I
haven't had a chance to look at this any closer.

Jonathan,

Fractint v.20.1.0, tested under: Win98 DOS box,
                                 Win98 DOS full screen,
                                 MS-DOS 6.22.

In each case Fractint _did_ find sstools.ini
when the file was removed from the Fractint directory
and placed in a directory PATH points to!

Greetings,
Gerald

Thanks.  On trying it again, I found that it only works if sstools.ini is in
the first directory in the PATH.  I think we still need to fix it to search
all the directories in the PATH.

Aha, that's exactly the situation on my PC.
Shame on me - I didn't even think of testing another sequence
of directories in the PATH statement!

With FRACTINT you got your work cut out for you. ;-)


Another item (not important, just asking):

Using 3d transform one has the option to output the
heightfield as a 24bit TGA file.
At the last prompt screen (light source options) the user can
specify a background color.
Documentation is missing a note on this also working as a
command line parameter ("background=nn/nn/nn").

Now, writing out the 3d transform (with TGA enabled)
into a .par file, "background=..." is not written to the file.
Could this be changed (without too many problems)?

Regards,
Gerald

Let me make a guess here.  You have a copy of sstools.ini in your Windows
directory with a [Winfract] entry in it.  In my case, Fractint was finding
this, and since no [Fractint] entry was in it the startup appeared as if no
sstools.ini file had been found.

At least now we know it works correctly.

I'll take care of these.

Tim,

I'll be uploading a patch this weekend.  Do you have anything you would like
included?

I found the problem causing the extraneous dots with the different fractal
types.  There are a couple of other bug fixes included, but I thought this
one was significant enough to warrant a patch.

No, go for it!

I'd like to try the latest Linux version, I better look and see where
we are.

Subject: Fwd: Question re: Mac OSX
Date: 20 Oct 2000 23:37:11 -0500

I recently received the following message about the possibility of
running Xfractint on OS X (on a Mac). I know she won't be able to run
the binary that I have up on my Website, but could she possibly
compile the source on OS X?

Do any of you Fractint developers know if OS X even comes with a
gcc-compatible compiler?

(I'll forward any replies to her, unless someone wants to write to her
directly.)

Scott Boyd

----------  Forwarded Message  ----------

I am planning to eventually run OSX on my mac computer.  Would I be able to
run Xfractint 3.11 on OSX's Unix?  Thank you in advance for any info you
have about this.  Charlotte Woodward

You can get a version of gcc for OS X, but I think you have to buy the
developer CD in addition to the OS X CD.  Also, you'd have to install an
X server, OS X doesn't come with one (despite the name..:)  There's a
website at <http://mrcla.com/XonX/> which tells how to do this.
I actually have a copy of OS X beta, so I guess I could try compiling
fractint myself to see what happens..:)

Thanks! I hope I could help. And could I ask what the hell it was? (if it's
not too complicated)

You helped by bugging me until I fixed it.  Thanks.

We don't do any error checking when we write to video memory.  The text
memory is equivalent to 24 rows by 80 columns.  We save the equivalent
amount of graphics video memory and replace it when we are done with the
text mode.  What was happening was, we were writing to rows 25 and higher,
leaving the erroneous pixels on the screen when returning to graphics mode.

Using the textsafe=save option saves the whole graphics image before we
start writing text to the screen and restores it when we are done.  So it
temporarily fixed the problem.

Date: 21 Oct 2000 17:00:14 -0500

Tim,

I've uploaded the patch.  Here's what's knew:

Fixed the <TAB> display screen so the video memory doesn't get overwritten.
This clears up the problem with extraneous dots with some fractal types.
It should be possible to remove the textsafe=save from your sstools.ini
file.

Added Iain Stirling to the scrolling credits screen for his contribution
of the inside=fmod and outside=fmod options.

Reworded the error message recieved when more memory is requested than
is available on your disk drive.

The background= parameter, for 3D TGA files, is now saved to a PAR entry.

Fixed the error message that appears when a parsing error occurs on
startup.

Cleaned up the savegraphics() and restoregraphics() routines.  This should
make them faster.

Jonathan

Subject: Another parser problem
Date: 21 Oct 2000 20:44:39 -0500

George,

The following formula and PARs illustrate a problem with using large bailout
values.  The problem goes away if the parser optimizations are turned off.
I don't see any obvious reasons for this to occur.  Any ideas?

frm:bailoutproblem {
;p1 is the bailout
bail=real(p1),
z=c=pixel:
z=z*fn1(z)+c
|z|<bail
}

1                  { ; this is ok
  reset=2000 type=formula
  formulaname=bailoutproblem center-mag=0/0/0.6666667 params=500000/0
  float=y maxiter=255 inside=0 sound=off
  }

2                  { ; the effect is visible
  reset=2000 type=formula
  formulaname=bailoutproblem center-mag=0/0/0.6666667 params=700000/0
  float=y maxiter=255 inside=0 sound=off
  }

3                  { ; the effect is very strong
  reset=2000 type=formula
  formulaname=bailoutproblem center-mag=0/0/0.6666667
  params=10000000000/0 float=y maxiter=255 inside=0 sound=off
  }

Thanks,
Jonathan
