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. WebThe Möller–Trumbore ray-triangle intersection algorithm, named after its inventors Tomas Möller and Ben Trumbore, is a fast method for calculating the intersection of a ray and a triangle in three dimensions without needing precomputation of the plane equation of the plane containing the triangle. Among other uses, it can be used in computer graphics to …
