Dynamic Voxel-Based Global Illumination

Global illumination computation in real time has been an objective for Computer Graphics since its inception. Unfortunately, its implementation has challenged up to now the most advanced hardware and software solutions. We propose a real-time voxel-based global illumination solution for a single lig...
