Ganovelli F., Ponchio F., Rocchini C. Fast tetrahedron-tetrahedron overlap algorithm. In: ACM Journal of Graphics Tools, vol. 7 (2) ACM, 2003.
We present an algorithm to test two tetrahedra for overlap. The algorithm is based on a dimension reduction technique that allows to apply the Separating Axis Theorem avoiding part of the computation needed to perform the Separating Axis Test. Source code is available online.
