SIMD_FORCE_INLINE GUINT GIM_TRIANGLE_CALCULATION_CACHE::cross_line_intersection_test ( ) [inline]

Test verifying interval intersection with the direction between planes.

Precondition:: tv_plane and tu_plane must be set

Postcondition:: distances[2] is set with the distance closest_point_u, closest_point_v, edge_edge_dir are set too

Returns:

0: faces are paralele
1: face U casts face V
2: face V casts face U
3: nearest edges
