Rigid skinning
- Attach rigidly subset of vertices to specific bones, described by its root joint/frame.
-
- Vertices are following rigid deformation of their associated frame.
Deformation formulation
- Consider, at rest pose/initial state
-
- - A frame \(\mathrm{T}^0\)
- - A vertex \(v^0\) attached to this frame
- After deformation
-
- - New frame \(\mathrm{T}\)
- - New vertex position \(v\)
- Question: What are the new coordinates \(v\) w/r \(\mathrm{T}\), \(\mathrm{T}^0\), \(v^0\) ?
