Physics simulation utilizing OpenCL for parallelized collision detection and OpenGL for rendering. This project is focused upon optimized computation and thus only supports simple circle-circle collision, but implements Spatial Hashing, along with a novel, dynamically-sized, shared memory vector system within the GPU for OpenCL calculation.
