* add test case * add coplanarity test * another failing test * use orient3d * no printing * reverting... That introduced lots of other failure cases * subdivided knight case * wip predicates * promising predicates version * tri_tri_overlap compiles, header guards, predicate find_* * tests for predicates::find_in... * parallel for * note * mv to predicates * remove old functions * tutorials; extracting segments is broken 904 * fix extraction bug * missing header * capture consts
