If you do go here: http://www.nvidia.com/content/forcewithin/us/index.html
You can download a “pack” that comes with a lot of cool stuff. On the fly fluid simulations demo, on the fly cloth simulation demos, etc.
I thought it would be cool to bring this up because Nvidia just came out with CUDA: http://www.nvidia.com/object/cuda_home.html#
It’s a development environment for C programmers that gives you access to the GPU and I think it’s free. I’m no programmer but I was wondering if it would be possible to make a render engine that makes use of the GPU in blender. The fluid simulations demo was extreemly fast on my 9600GT (10 to 15 frames per secound) maybe it would also be possable to bake simulations using the GPU too?
All of this is just theory and I’m not sure how well all of this would work out but any thoughts?
