Hello,

I'm working with Processing and GLGraphics to produce various cellular 
automata simulations. I've just found something worth sharing, and was 
wondering if somebody might help me test it out. It requires Java and a 
newish graphics card (GLSL, Pixel Shader 2.0+).

You can draw bubble-producing explosions with the mouse. Tap inside a 
medium-sized cell to "pop" it. The space bar clears the screen.

It will probably run blindingly fast on newer cards, slower if your card 
is old, not at all if it's ancient. I get 30FPS on my GeForce 7600GS . 
It would be faster, but I'm using 16-bit surfaces.

The simulation itself is based on an edge-finding technique combined 
with diffusion and a method (developed with POV-Ray) for 
pinching/expanding densities. As the field stabilizes, the result 
resembles a minimal surface.

I was hoping to use something similar to make a suds effect for MilkDrop :)

I get a note at the bottom saying "class not found: RDMinim"

(When you describe it, you might want to mention it's an applet and not a 
stand-alone java program.)

I just get a very small black square and nothing much happening (oh and 
Java crashes when I try to close the webpage).

Sounds exciting though, can you post some screen shots?

Works flawlessly for me (with Firefox, on a not so new computer).

It's mesmerizing !

I just uploaded it to a new directory:

This is my first time uploading such a thing... I'll have to look into 
it. It has its own directory now, so maybe it will work:

http://www.caltel.com/~abenge/applet/index.html

Ah yes, I should have mentioned that :S

As it turns out, there were two places to change the window size, so it 
should be fixed now.

That's not very encouraging :(

> Sounds exciting though, can you post some screen shots?

I will, if the app still refuses to run. A series of PNG files would be 
best, but they take a long time to upload...
