Fast Tetrahedron-Tetrahedron Overlap Algorithm
Fabio Ganovelli, Federico Ponchio, C. Rocchini · Journal of Graphics Tools · 2002
We present an algorithm to test two tetrahedra for overlap. The algorithm is based on a dimension reduction technique that allows the application of the Separating Axis Theorem, thus avoiding part of the computation needed to perform the Separating Axis Test. Source code is available on the website listed at the end of this paper.
