Rotation Invariant Spherical Harmonic Representation of 3D Shape Descriptors
One of the challenges in 3D shape matching arises from the fact that in many applications, models should be considered to be the same if they differ by a rotation. Consequently, w...

Interactive collision detection for complex and deformable models using programmable graphics hardware
In this paper we present an interactive collision detection algorithm for complex and deformable objects. For two target models, our approach rapidly calculates their region of in...
