Title: Latest 3D raytraced volumetric flame animation Post by: doncasteel8587 on February 16, 2007, 11:42:33 PM 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.
