Reflective Shadow Maps

There is a nice extension to shadow mapping that allows for the rendering of plausible indirect illumination. It's not quite as performant as voxel cone tracing, but it introduces some ideas on how we can model the behavior of light. Every pixel in the shadow map is considered as an indirect light source and we … Continue reading Reflective Shadow Maps

Global Illumination Using Voxel Cone Tracing

Facilitating a reasonable and accurate physical description of light in the presence of real-time constraints has always been the driver of work in the field of interactive computer graphics. For me, what makes voxel cone tracing so intriguing is the combination of a less canonical data structure (i.e., the voxel representation) as the center point … Continue reading Global Illumination Using Voxel Cone Tracing
