Constant Normal (Normal to Surface)
The z-axis is along the direction defined by the constant normal reference. The y-direction is set by the projection of the surface normal in the constant normal direction.
1. Constant normal plane
2. Projected surface is normal along the constant normal reference
3. Actual surface normal direction
4. Origin trajectory
