fillLocalXYTriangleFrame Method

  • Triangle for (unchecked!) for three points identified by index
  • z direction of frame is 001.
  • Transform axes from origin to targetX and targetY
  • 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 invertible (i.e. points are not in a vertical plane.)
