Title:

    Point-based rigid shape interpolation

Abstract:


    Nearly rigid interpolation has been shown to generate good interpo- lation results for both 2D and 3D shape morphing problems [Alexa  et al. 2000]. The key to success of most proposed techniques like  that of Alexa, et al. is generating a high-quality compatible triangu- lations of the source and target shapes in 2D and compatible tetra- hedralizations in 3D. A number of good methods are available for  the 2D case, however, it is more difficult in 3D. The 3D rigid mor- phing example demonstrated by Alexa et al. [2000] has, by con- struction, a fairly trivial compatible tetrahedralization; however, for  real-world cases, where the inputs are typically 3D meshes without a priori tetrahedralizations, the task is much more difficult.
