Vertex Animation Toolset, crowd rendering

[Starkium]

I was only “the user” of the system but I didn’t develop it so I don’t know any of the implementation details.
some details that might be useful:

• the skeleton’s bones were mapped to a “vertex-bone table texture” (HDR, texture size X = number of mesh vertices, Y = 2px but I have no idea how the mapping was done)
• the animations were 3 textures per anim (HDR, texture X = number of bones, texture size Y = number of animation frames, each texture corresponding to X, Y and Z matrices respectively)
• the material would evaluate the passed anim texture against the vertex-bone table texture with a custom function (no idea how it did what it did) and plugged into WPO

That’s something, I’ll take it! Thank you very much for the insight.

What would be cool is if I could figure out how to get vertex animated static meshes to update their collision with the vertex animation.

Also, they were probably doing something related to this: SkinnedInstancingWhitePaper (nvidia.com)
