Hi everyone,

I have created a new snowflake generator for Windows. It is a complete 
rewrite and is based on an iterative fractal function. It produces 
fairly realistic snowflakes.

You will need DirectX v8.0 or above for this program to work. There are 
many options available, including support for different image resolutions.

The link:
http://www.caltel.com/~abenge/hgeFractalFlake1.zip

Just unzip the file into a single directory and you're good to go!

Some example images:

Enjoy!

Sadly, also doesn't run under WINE (though the result is a bit more 
spectacular - I see the help text flashing, but when I say "go", the 
machine crashed *hard*) or in W2K under VMware. :-(

One thing you might check. Does your video card support antialiasing or 
anistropic filtering? If so, are those settings 'application controlled' 
or have you overridden them? If it's the latter, disable them. Other 
than that, I can think of no reason for the crash :(

I'm not sure if Linux has ways to change that. I think it's only nVidia 
cards on Windows that give such settings.

I could not find the pov-output switch :(

I never alluded to such a feature. I posted the program here because you 
can use the resulting bmp (saved via. F2) in POV like so:

pigment{
  image_map{
   sys"snowflake.bmp"
   interpolate 2
  }
}

If I can figure out dynamic arrays and formatted text output, I could 
make a version which outputs to a POV include file.

Well that's a bloody shame. With nVidia cards you can use those settings 
to play 3D games with antialising! It improves the quality manifold.

	nVidia cards on linux have it. AFAIR ATI cards on either Windows or
Linux have it too.

I think it is not exactly how you do it in bmp, but what about blob objects?
Though they might be slow, I seldom use them.

If you use OGL, you will have beter compatibility. Then, it will be easier to 
port to other OS, and have beter chances of running under a VM or emulator.
