Bool Cuts(C Vec &point, C Tri &tri) strange behaviour
Code:
Tri tri;
tri.p[0] = Vec(3.42183304, 0.00000000, 9.04267216);
tri.p[1] = Vec(-7.13797712, 0.00000000, 9.04266930);
tri.p[2] = Vec(3.49913740, 0.00000000, -1.78532219);
Bool cuts0 = Cuts(tri.p[0], tri); // true
Bool cuts1 = Cuts(tri.p[1], tri); // true
Bool cuts2 = Cuts(tri.p[2], tri); // false
Is this normal that using Tri's own point in Cuts gives more or less random answers?
For p[1] = Vec(-7.16797712, 0.00000000, 9.14266930) all cuts are true
I checked source but such math is beyond my level.

Yes that can happen for points near the border.
If you need some tolerance to make sure these points will be included then try using CutsEps function
