Abstract: The voxels structure principle of 3D model as the foundation, expounds the voxel geometry
information and body elements of topological relations and benchmark problems, establish the 3D
model feature extraction function and of its rotation, translation and size changes of classic moment
invariant processing, put forward a based on voxel structure and genetic algorithm of 3D model
retrieval method. This method reduces the convergence speed of the search area and improves the
retrieval accuracy and retrieval speed by the genetic information encoding, the genetic information in
the iteration and the variation of the genetic information.
