Shape Editing
1. How to represent 3D shape in the Riemann space?
Euclidean space versus Manifold space
Local coordinate system: Laplacian coordinate
2. A few notations of differential geometry and its explanation
3. Deformation matrix and the optimization function
Laplacian shape editing
4. Shape editing in latent space.
represent shape with a latent code, and deform the shape by moving the latent code to a new position in the latent space.
Examples:
- DeformSyncNet
- DualSDF
