This project explores a computational method to create controlled cuastics. I experiment with a process to transform pixels into caustic images—patterns of refracted light.
Pixels to Lux
The process to convert an image into a 3-dimensional refractive surface is informed by Yue et al.'s 2014 paper on goal-based caustics and continues work done by Matt Ferraro. It involves creating a mesh to achieve a specific caustic pattern. Each mesh cell directs an incoming ray of light to the appropriate position in the refracted image such.
