I posted a small "bonus" demo that I've been distributing as a supplement for the Bounded Biharmonic Weights for Real-Time Deformation MATLAB demo. This shows a full pipeline for the alligator example in Figure 5 of our paper and in our videos. The example uses point, bone, and cages on the sample 2D character. The demo is now included in the bbw.zip folder of matlab code and can be called by issuing:
