Rendering the Real-Time Caustics with DirectX Raytracing
http://ceur-ws.org/Vol-3027/paper4.pdf
This equation is traditionally solved with methods of backward ray tracing [6], forward ray tracing [7], bidirectional ray tracing [8] and its modifications [9], forward [10], and backward [11] photon mappings. The most effective methods for caustics visualization are based on the photon mapping [12][13] or backward photon mapping [14]. When ...

3. Forward and Backward Ray Tracing . Ray tracing is a method of rendering an image by tracing rays on the object. If the traced rays of an object and the calculated intensity of the color of the object. Ray tracing method is divided into two types, namely forward and backward ray tracing ray tracing. Forward ray tracing is used

Caustics Mapping: An Image-space Technique for Real-time …
http://graphics.cs.ucf.edu/old/caustics/index.php
Caustics Mapping is a physically based real-time caustics rendering algorithm. It utilizes the concept of backward ray-tracing, however it involves no expensive computations that are generally associated with ray-tracing and other such techniques. The main advantage of caustics mapping is that it is extremely practical for games and other ...

traced backwards from the light source into the scene as opposed to conventional ray tracing in which the rays emerge from the eye. Photon mapping, a more flexible framework, was proposed by Jensen [9] which handles caustics in a natural manner on arbitrary geometry and can also support volumetric caustics in participating media [10].
