Graphics researchers have long studied real-time caustic rendering. The state-of-the-art technique Adaptive Caustic Maps provides a novel way to avoid densely sampling photons during a rasterization pass, and instead adaptively emits photons using a deferred shading pass. In this project, we present a variation of adaptive caustic maps for real-time rendering of caustics. Our algorithm is conceptually similar to Adaptive Caustic Maps but has a different implementation based on the general-purpose computing pipeline provided by OpenGL version 4.3. Our approach accelerates the photon splitting process using compute shaders and bypasses various other performance overheads, ultimately speeding up photon generation considerably.
