Interactive volume caustics in single-scattering media
Wei Hu, Zhao Dong, Ivo Ihrke, Thorsten Grosch, Guodong Yuan, Hans‐Peter Seidel · 2010
Volume caustics are intricate illumination patterns formed by light first interacting with a specular surface and subsequently being scattered inside a participating medium. Although this phenomenon can be simulated by existing techniques, image synthesis is usually non-trivial and time-consuming.
