→Ray Tracing
Ray tracing is a rendering technique for generating an image by tracing the path of light as pixels in an image plane and simulating the effects of its encounters with virtual objects.
The technique is capable of producing a very high degree of visual realism, usually higher than that of typical scan line rendering methods,but at a grater computational cost.(Wikipedia [https://en.wikipedia.org/wiki/Ray_tracing_(graphics)]).
