Web18 aug. 2011 · Mathematically, if you think of a triangle being made of points P1, P2, P3, you do the normalized Cross Product of P1 to P2, and P1 to P3. There is a Vector3.Cross () function to help with that. It's been a while but that should give you the normal. The center point is just the average position of P1, P2 and P3 or ( (P1 + P2 + P3) / 3). Web16 apr. 2024 · Don't let textural features cross triangle edges. Ever. Simple. You want to find the "fattest" triangles, i.e. tris where there is a lot of room to work, and start generating textural features from (near) their centres.
