Transforms between coordinate systems. After using TFormPoint the new
coordinates can be read with TFormedX(), TFormedY() and TFormedZ(). See EntityX() for details about local coordinates. Consider a sphere built with CreateSphere(). The 'north pole' is at (0,1,0). At first, local and global coordinates are the same. As the sphere is moved, turned and scaled the global coordinates of the point change. But it is always at (0,1,0) in the sphere's local space. |
