Hello Everyone,
Just in time for the holidays! It's a random snowflake generator. Far
from being an accurate simulation, it does produce better-looking
snowflakes than most programs available today(until I find a better
one). You can save a 700x700 screenshot to file.
The program(with instructions) can be found here:
http://www.caltel.com/~abenge/snowflake1.zip
And a screen shot can be found here:
http://www.caltel.com/~abenge/snowflake.jpg
C++ source is also included. Enjoy :)

I like it! It would make a cool screensaver. Any Idea how to make it into a
screensaver? (Windows XP)

Make it shut down when it receives any mouse movement or keyboard input,
and make it full screen instead of windowed. Screensavers are just .exe,
renamed.
I tried using it as a screensaver, as is. The windowed mode kept it from
starting full screen, which was a bigger down side then having to hit
escape to turn it off.

I really like this program and just in time for Christmas. I do have
one problem though. On my PC it runs too quickly, ( I never thought
that I would say that about any program)
I do not have access to any program that I can use to try amd modify
the source code and certainly nothing to compile it with.
Is it possible for you or someone who knows what they are doing to
make it run much more slowly. Perhaps a key board shortcut to step
through one iteration at a time ?

Thanks, Sabrina, for the info.
I copied the files into windows/system32 and renamed snowflake1.exe to
snowflake1.scr, then it was on the dropdown list for selecting screensaver
in the desktop properties setup. I selected it for the screensaver, and it
works!

Hmm, it shouldn't be much trouble to make such a version.

Once again, that shouldn't be too hard. I might as well have it display
colors and refresh the screen once in awhile, too. 1024x768 is pretty
much standard these days, right?

Wow, I didn't know it would be so easy! I might wait till I get Windows
XP to release the next version (should be a day or two).

My brother *was* right! I does run too quickly. He also suggested I make
a way for it to step through each frame. I figured using the left mouse
button to pause it would be sufficient, but I guess not. What's your
processor speed?
I hope to release another version soon. Glad you liked this one!

If you're open to suggestions, I have one. After it has been running for a
while, it fills in so much space that it just becomes a big circle and
doesn't look like a snowflake any more. How about limiting the number of
changes it can make, so that when it reaches the point where it is starting
to look like something other than a snowflake, it goes back to zero and
starts over with a new one.

IMHO it would be enough to simulate a "space"-push every once in a while
, could be randomized between 5 and 20 seconds.
This would be looking great and really make a nice screensaver.

Too late. I'm already developing a version which uses fractal recursion
to form the branches of the flake. It's a near-complete rewrite, but
it's almost finished now.

No wonder! I've got a measly 1.6ghz pentium over here.... but will soon
have a new system with a quad core. That will be a happy day :)

The new version might not look too great as a screensaver, since it
draws the flake all at once. I'll see what I can do.

Are there any prerequisites that need to be installed? Tried running it
under WINE and it just hung, and in W2K under VMware it seems to crash
out with no error message. I actually get further under WINE (I get the
initial splash screen).
I figure I must be missing a required dependency.

1024x768 and UP!
It's been my minimum resolution since 1995... At the time, I was using 256
colours, but quickly upgraded to 16 (high colour), then 32 bits (true colour).

I have no idea how to help you. You might need to get Dev-C++ and
recompiled it for your machine. What version of DirectX do you have?

I didn't need Dev-C++ to run it on windows, so I'll guess that isn't the
problem.
A quick check of the call stack for snowflake1.exe gave me:
ntkrnlpa.exe
ntkrnlpa.exe!ProbeForRead
ntkrnlpa.exe!KeReleaseInStackQueuedSpinLockFromDpcLevel
ntdll.dll!KiFastSystemCallRet
kernel32.dll!Sleep
hge.dll
The hge.dll is included in the zip, but it could be that WINE isn't
finding it. You might check if the Haaf's Game Engine can run under
WINE. The other files I think are ones that WINE should handle.

You need to get Dev-C++ to *recompile it from source* for your machine,
if you were going to use the suggestion of recompiling.

Under WINE it indicates dx8 is being used, (but it is emulated so maybe
just some missing functionality). In my W2K VM, I show ... whoops, looks
like I might not've installed any version. Will fix that and try again
in the VM.
The error message under WINE is:
err:wgl:X11DRV_wglGetProcAddress (wglMakeContextCurrentARB) - not found
err:wgl:X11DRV_wglGetProcAddress (wglGetCurrentReadDCARB) - not found
fixme:win:EnumDisplayDevicesW ((null),0,0x61f444,0x00000000), stub!
fixme:d3d:IWineD3DDeviceImpl_GetAvailableTextureMem (0x136bd0) : stub,
simulating 64MB for now, returning 64MB left
fixme:d3d8:IDirect3DDevice8Impl_GetDepthStencilSurface Call to
IWineD3DDevice_GetDepthStencilSurface failed
So this looks like a WINE issue.

Hopefully you can get it working, since I've got a new version almost
complete. It produces more realistic snowflakes, and is based on an
iterative function. Stay posted...

DirectX 9 on W2K now, no luck, though. :-(

Hi Sam,
Wow, this is really cool! It works fine, and the processing of
snowflakes looks very beautiful. I will try out the bitmaps with povray
as soon as I got some time.
