Abstract

In this paper, we established an algorithm to obtain 3D shape descriptors based on a novel force field model. Based on this model, 3D models as surface particle sets are assumed and the force interactions between particles are computed to constitute a spherical descriptor. During the force computation, the mass of the particle is defined to maintain local information which improves the discrimination of the spherical descriptor. The experimental results show that this algorithm is valid for 3D shape matching with high efficiency.
