This 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.

The ray-tracing algorithm takes an image made of pixels. For each pixel in the image, it shoots a primary ray into the scene. The direction of that primary ray is obtained by tracing a line from the eye to the center of that pixel. Once we have that primary ray's direction set, we check every object of the scene to see if it intersects with any ...

Recent advances in algorithms and compute power has made Monte Carlo ray tracing the natural choice for most problems. This is a significant change from just a few years back when the (finite element) radiosity method was the prefered algorithm for most graphics researchers. Monte Carlo ray tracing has several advantages over finite element ...
