It's open source, being folded into Blender, and you might say it holds a fractal array of voxels (technically a fast shallow and sparsely populated binary tree). It's currently used by, e.g., Dreamworks SKG to make fire, smoke and water in Hollywood movies.
The neat thing is each voxel can have have non-spatial attributes like color, opacity, velocity or pressure. I'm sure what we want could be built on Blenders animation engine. |
Anything useful to us would have to rely on the full Navier-Stokes Equation.It uses a spherical vector coordinate system and each cell's performance is dependent upon the pressure and velocity of all cells surrounding it.
It requires a supercomputer to run it and takes almost 2-days to solve a single iteration.
No desktop computer can do this yet.And if you call the companies who sell it,you better be able to prove that your a deep-pocket corporation or well-granted university before they'll even talk to you about their products.
