Caustics Effects with Photo-Realistic Rendering on Movie("Cars\´)

Caustics effects caused by light refraction play an important role in photorealistic rendering to realize rendering like photos. This paper examines caustics effects for light and materials in photorealistic rendering techniques. This paper analyzes caustics used in ´Cars(2006)´ of Pixar and realizes caustics effects by using ´Vray´ used frequently for photorealistic effects recently. And this paper examines the use environment of each variable and better expression to realize effects. The results can be used as data on characteristic and capability for realization of caustics effects.
