TriangleModelNodeNormal Property

The normal vector of the triangle. If not set, then it is calculated as a cross product of (P2 - P1) and (P3 - P1). After the normal vector is set manually, it will not be recalculated automatically. Property change will re-generate the mesh in the next update phase. To immediately re-generate the mesh, call the Update method.
