Detailed Description

Class for 2D-2D intersections.

Computes the intersection of triangle A and triangle B. Uses 6 ComputeIntersection<1,2>:

3x side of triangle A X triangle B
3x side of triangle B X triangle A

It creates a final intersection.

TODO: do not remember, if the function correct_triangle_ip_topology used to have some meaning here..

Member Function Documentation

◆ clear_all()

void ComputeIntersection< 2, 2 >::clear_all ( )

◆ compute()

unsigned int ComputeIntersection< 2, 2 >::compute ( IntersectionAux< 2, 2 > & intersection )

Computes final 2D-2D intersection. Computes CIs (side vs triangle) in following order: [A0_B, A1_B, A2_B, B0_A, B1_A, B2_A]. During cycle determine topology information and set computed flags accordingly.

Parameters

intersection final 2D-2D intersection object (output)

Returns: number of intersection points found
