Shape Segmentation with HFP

I have just combined the fitting primitives mesh clustering (HFP) algorithm proposed by Marco Attene in is paper "Hierarchical mesh segmentation based on fitting primitives" with the prototype that produces the spherical harmonics descriptor (SHA) and cord and angle histogram (CAH) for a 3D model. The result is an application that decomposes a model using the HFP approach and then computes for each segment the corresponding descriptors. This application produces a navigable VRML file containing the segmented model. By clicking on segments it is possible to see the descriptors for that segment and even the segment alone or a possible random sampling. To view an example based on a model extracted from the ESB click on screen-shot below.
