| Research Abstract |
In this research, we developed methods for automatically computing the geometry of the transparent refractive object which produces a desired caustic pattern specified by the user. First, we developed a method to represent the surface refracting the light (refraction surface) using a discrete set of facets. Then we developed another method for making the object rearrangeable, by incorporating a set of transparent refractive sticks. By rearranging the same set of sticks, we can obtain different caustic patterns (pixel art). Finally, we developed a method for computing continuous refractive surface, and enabled production of high quality caustics, including sharp and thin features.
