Dynamic Virtual Method Not supported

In programming we some times need to choose between several implementations of the same functionality based on the run-time types of several arguments. This is called Dynamic Multiple Dispatch. One example of Dynamic Multiple Dispatch is the geom-etry dispatcher in OpenTissue, which takes a pair of geometry objects and selects a collision-detection function based on the objects type. Unfortunately C++ does not support Dynamic Multiple Dispatch natively, and the previous implementation of the geometry dispatcher used static type enumeration, a static function lookup table and conversion through void pointers. In this project I have explored two methods for approximat-ing dynamic multiple dispatch in C++ and I have compared their flexibility, limits and performance. Finally I have implemented the best suitable method in OpenTissue and compared it against the previous implementation
