CAS/HFP versus HFP

During the last weeks I've been implementing the context-aware decomposition based on hierarchical fitting primitives (CAS/HFP) algorithm. Now that I finally have a working prototype, I was able to compare the result produced by CAS/HFP with the ones produced by applying only the hierarchical fiting primitives (HFP) segmentation. To that end I use a very small collection extracted from the PRECISE Engineering Shape Benchmark. Below I show the segmentation trees produced by the two algorithms for the same shape.
