Computing Spherical Harmonics Descriptor
Based on work by Michael Kazhdan, I implemented a prototype that produces the spherical harmonics descriptor (SHA) for a 3D model. To that end I used not only the executables for computing SHA representations provided by Kazhdan, but also some code developed by Simone Marini to read the binary signatures. The results produced by my prototype for shape m87 from the PSB (the dog model I often use) are illustrated below. You can also take a look at the VRML file containing the 3D SHA representation of this model.
