unsigned int 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
