Detailed Description

Auxiliary class used to find self-collisions of a triangulated surface mesh

Instances of this class detect different types of self-collisions such as in particular self-intersections between non-adjacent as well as adjacent triangular faces and a list of non-adjacent faces which are about to collide, i.e., very close to each other. They are used to impose either hard or soft non-self-intersection constraints on a deformable surface.
