Latest 3D raytraced volumetric flame animation

[doncasteel8587]

This is my latest animation. I've improved the transparency and refraction as well as a smoothing algorithm for creating the volume itself. It's sorta like anti-aliasing, but is done as the iteration points are added to the volume, it's really more of a "Gaussian splatter" function.

This format is supposed to be mpeg4 yet seems to play in Windows Media Player, please let me know if you have trouble.

the compression is really extreme unfortunately nevertheless one can make out the smoother volume data quite clearly, it's good that you're not doing vol[z * (xres * yres) + y * (xres) + x]++ anymore, that must have been hell for your continuous refraction code!

a friend of mine sent me a link recently, which links to the other:

i figure getting your data into the first link's code should be really really simple; all you need to do is find a gf6/7 gpu with a decent amount of memory and you should be set for a 1000x or more speedup.
