I *think* I have fixed the problem by replacing ">" by ">=" on lines 664 and 666. Please keep an eye on this function for the coming weeks...  It appears that function vgl_intersection() has a bug: It cannot detect intersection when components are two's complement. e.g. vgl_plane_3d pl1(1, 0, 0, 0); vgl_plane_3d pl2(0, 1, 1, 0); vgl_line_segment_3d inter; bool intersect = vgl_intersection(inter, pl1, pl2); intersect value is false but should be true.
