Ray casting-based method
WebThis is the reason why forward racing is also known as light ray tracing or photon tracing. 2. Backward Ray Tracing Algorithm. This method is used to get over the inefficiency of the forwarding ray-tracing method. In this method, an eye ray is created near the eye which passes through the view plane and into space.
