IntersectionAux< 2, 3 > * | intersection_ |
Class for 2D-2D intersections.
Computes the intersection of a triangle and a tetrahedron. Uses 3 ComputeIntersection<1,3> for triangle sides vs tetrahedron intersections. Uses 6 ComputeIntersection<1,2> for tetrahedron sides vs triangle intersections.

void ComputeIntersection< 2, 3 >::compute | ( | IntersectionAux< 2, 3 > & | intersection | ) |
Computes intersection points for 2D-3D intersection. Computes lower dimensional CIs: 1) 3x triangle side vs tetrahedron 2) 6x tetrahedron edge vs triangle During cycle determine topology information and set computed flags accordingly. Finally, tracing algorithm is called to sort the intersection points to create convex polygon.
intersection | final 2D-3D intersection object (output) It is then used further in prolongation decision routines. |
Compute triangle side - tetrahedron intersections IPs order is given by orientation of triangle sides, sign of IP results influenced by S3 inversion is irrelevant.
