Two points:

  - Just because there are dozens of lousy slow buggy etc. fractal
generators in Java about on the Web, it doesn't mean they have to be
that bad.
  There are hundreds of really bad fractal programs for DOS, but that
doesn't stop Fractint being great.

  - AFAIK if you install the Java Development Kit (JDK) from Sun, you
can save files from Java apps.

To those of You who are discussing Java :

There is a very nice Fractint utillity called Filmer written in Java by
David Mansfield at :

 http://ariel.cobite.com/~julian/filmer/

 You will even find the source of the program at thos site!

  I think it's debug=3D500, then you must use type=3Dtest.

Subject: (fractint) textsafe=???

I've tried to use the TEXTSAFE=SAVE parameter because when I switch away
from Fractint in WIndows to do something else, and then try to switch
back, the whole image is trashed!  Unfortunately, when I try to do this
using the "g" command, Fractint gives me the funny error noise and says,
"Oops, I couldn't understand the argument textsafe=save."  This seems
odd because other people have posted messages saying that they use it.
Should I be using this as a command-line parameter, or in a config file,
or what?  Or is my version of Fractint just busted?

Please ignore this.  I went and actually tried textsafe=save as a
command-line parameter, and it worked!  I should really learn to try
everything before writing in with a problem... DUH!!!!!!

On an MC68060 its 2 cycles for a 32 Bit int multiply (and the cpu can
put that into a pipeline and do other stuff inbetween) and more for
fpu. I think even with 64 Bit ints its faster than fpu. This is also
true for other cpu's. On intel cpu's the fpu is highly optimized and
much faster than the crapy int unit. Thats why you gain with fpu
there. I vote against removeing the int code, but for porting it to 32
bit and 64 bit.

you can do x^2 and y^2 at the same time with mmx. You can also emulate
a 32/64 Bit multiply with a few four 16x16 multiply cycles. I think it
won't be much slower and you also have more registers to store the
numbers and don't need to write to memory.

Why not use a library that does this? There are libraries for n Bit
interger operations out there which can be utilised. One just have to
find one that is optimised for small integers and one for big integers
(>256 Bit).

May the Source be with you.

You're aiming for V50 being Java could be right and before that
Version javal probably will in no way be usable for highly cpu
demanding stuff like fractals. Fractals are pretty much the only
things left that are worth writeing in asm for. Java might or might
not ever be fast enough and at the time being its unuseable for
anything but dreams and www aplets.

If the aim is to have fractint running on any computer then C is the
way to go and C is fast enough. Also it's easy to have inline asm for
various cpu's. C++ or Objective C is also an option and there isn't a
differenc in speed if it's done right.

With todays compilers for C its also hardly neccessary to write inline
asm for more then the bare core of the formula (if even). On a PPC for
example the iner loop of a Mandelbrod Fractal can be written in 6 asm
lines, the rest of the programm can be wastefull, because its hardly
used.

May the Source be with you.
            Mrvn

        There was TWO different category of
        Java programs

Java "applets" (downloaded from the Net and running in
a browser, in a Web context) can't access the local file
system.  --> Security

Java "applications" (running from the command line)
have the same access to the file system than others
applications.

Best Regards from Toulouse, France.
        Thierry.

p.s. If you remove Int math from Fractint, you can rename
  "Fractint" to "Fractint" (Fractals are Internationals :-)

Ah. Okay, I wasn't sure whether applications had the same limits as applets.

Dunno. Why do you end every line with "=3D"?

I don't do it on purpose... Using Outlook (not Express), that might =

It does this to me too in Win 95 on my 486dx2 50 with 8 megs ram. It
doesn't on my *new P166 with 32 megs RAM ;) ;) ;)*... so it has =
something
to do with ram/speed.

Hum... I have a P90/24Megs... should be such a problem either... But =
like I said, it ain't that bad anyhow.

[Smallish binary snipped]

I think it's poor netiquette(?) to post binaries here... PAR files and
formulas are welcome though.

Again, I don't know where that came from... Is it happening again? I =
changed a few options before sending this particular message... An email =
might be a better idea...

I'm keeping it to Fractint from now on, with one last request: could you =

get way off track...

From: (Originator) Nigel Long,

re: Diamond stealth 200 Pro video card.

This card uses an S3 Virge chip, and is the OEM version (not retail). Every time I
try to access one of the VESA autodetect modes it tells me that this mode is not
supported by my card. It works fine with other DOS apps however.

I am not interested in the modes greater than 256 colors, but I do have a huge
collection of 1024x768x256 images I use all the time, and it would be nice to be
able to use them.

I am not using windows in any flavour when I try to run Fractint (I have a dual boot
configuration). Everything points to Fractint's VESA detection failing with this
chipset, but why? since other people seem to have no problems. Are any of you
using any kind of extra VESA driver to run the card in DOS?

Nigel Long.

That's what happens when people post messages with the

Subject: (fractint) Color Maps

I've just started trying to write my own .map files. And I have some
questions.
1. How many combinations are possible? I would think that there are only
256, assuming red=1, grn=1, blu=1 would be the same as red=120, grn=120,
blu=120. Otherwise there would seem to be a factorial of colors (256!)

2. Is there a nice list of numbers coordinating with their respective
colors?

I hope this doesn't come across as TOO lazy. But I will send a FREE
Newsted Fractal to anyone who responds! Really! (noe how could you
possibly pass THAT up??!!)

Thanks,
Nuke
p.s. Ever observe fractal conversations in your morning meetings?

Color maps select 256 colors from a palette of 16.7 million (2^24).
So there are 16.7 million distinct colors from which you can select
256 to place in the colormap.

I'm not sure what you're asking for here?  Typically fractint uses the
iteration count as the index into the colormap to color a pixel.
Various options change this behavior, and the concept of "iteration
count" doesn't have the same meaning for some fractal types (cellular
and ifs come to mind)

   You should interpret these as intensities. You're mapping the
truecolor, 16.7 million palette (256 cubed, not factorial) to a 256 color
palette. 0,0,0, is pure black; 1,1,1, is a very dark grey; 255,255,255 is
white.

> 2. Is there a nice list of numbers coordinating with their respective
> colors?

Obviously not, for so many. There are a number of utilities that do
nothing but show you what a colorvalue produces; I can't point to any
offhand, but as most were made to help write web pages you might look in
that direction. The palette editor and the eyedropper tool of any paint
program (i.e. paintshop pro at jasc.com) will also be able to do this.

End of fractint Digest V1 #30
*****************************

To subscribe to fractint Digest, send the command:

    subscribe fractint-digest

in the body of a message to "[e-mail]".  If you want to
subscribe something other than the account the mail is coming from, such
as a local redistribution list, then append that address to the
"subscribe" command; for example, to subscribe "local-fractint":

    subscribe fractint-digest [e-mail]

A non-digest (direct mail) version of this list is also available; to
subscribe to that instead, replace all instances of "fractint-digest"
in the commands above with "fractint".

Back issues are available for anonymous FTP from ftp.xmission.com, in
pub/lists/fractint/archive.  These are organized by date.
