Surface features
MOTIVATION: Extract features (bumps, ridges, valleys, inflections) from arbitrary surfaces at multiple scales. Applied to line-based rendering, illustrative shading, 3D shape editing, etc. | INSPIRATION: Guennebaud et al work on Algebraic Point Set Surfaces. Koenderink et al work on solid shape invariants. |
