Member Function Documentation

void ComputeIntersection< Simplex< 2 >, Simplex< 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.

Parameters

intersection final 2D-3D intersection object (output) It is then used further in prolongation decision routines.

Returns: number of intersection points found
