Hybrid framework for blendshape manipulations

We propose a hybrid blendshape manipulation framework to accelerate the face posing process. The hybrid framework enables interactive edits with direct manipulation and face-constraint-relaxation, which also avoid face geometry distortion during operations. An underlying primitive in this framework is a constraint blendshape model, which operates indirectly sliders by solving a simple least square problem. We demonstrate the effectiveness of our framework with a few application results.
