                Pseudo code and notes for generating a vertex animation texture for a fixed point count deforming geometry.
              
          
    Vertex Animation Textures

Prerequisites


Normals
UVs

Create orient attribute (allows us to update normals in the vertex shader)


Create normal (N) attribute if missing
Create tangentu attribute (preferably MikkT)
Create matrix3 from N and tangentu
Convert matrix3 to orient attribute (quaternion)
