Abstract

An improved modeling system and associated techniques are described herein. In various embodiments, a modeling system generates a spatially local PCA model where the parts are connected with continuity constraints (e.g., soft constraints) in the boundaries. Experimental results on 3D face modeling show that the spatially local PCA model generalizes better than a holistic model. Moreover, the modeling system smoothly varies local control points for face posing in animation.
