Fast Ray-Tetrahedron Intersection Using Plucker Coordinates
Nikos Platis, Theoharis Theoharis · Journal of Graphics Tools · 2003
We present an algorithm for ray-tetrahedron intersection. The algorithm uses Pliicker coordinates to represent the ray and the edges of the tetrahedron and employs a rob ust and efficient test to determine the intersection. The algorithm is highly optimized and provides a significant performance increase over related algorithms. Source code is available online.
