A 3d shape search engine written in java, based upon Spheric Harmonics transforming of a 3d shape. Current it support OFF file format only.
I uploaded several papers which I referred during building the codes, those papers are not written by me.
The system uses Spheric Harmonics transform(SHT) to form a rotation invariant shape descriptor,a high-dimensional matrix. Cover tree is used for k-nn search.
Similar Project hosted on Google code:cybervision, A next-generation 3d model search engine too.
Release Notes on 11-July-2010
A cover tree for similarity search has been implemented. It is improved cover tree algorithm by applying priority sweeping at search stage.
XXL package was discarded, the new cover tree package is much better than XXL.
Further works and known issues
Though cover tree is much better than MTree or XTree both in terms of I/O and the
