fillLocalXYTriangleFrame Method
Compute frame for a triangle formed by three (unchecked!) points identified by index.
- z direction of frame is 001.
- Transform axes from origin to targetA and targetB
- in local coordinates (u,v,w) the xy interior of the triangle is
u>=0, v>= 0, w>= 0, u+v+w<1 - Return undefined if transform is not invertible, e.g. if points are in a vertical plane.
