Ambient Light Caching via Approximate Photon Mapping

Indirect illumination is an essential part of realistic computer-generated imagery. However, accurate calculation of indirect illumination comes at high compute costs. To this end, we replace lengthy indirect illumination paths by employing an ambient light cache based on photon mapping principles. By only performing cache queries after a...

Dynamic Indirect Illumination in Real-Time Ray Tracing using Lightcuts

This thesis describes a system that adds plausible indirect illumination to the Arauna real-time ray tracer. Only the first diffuse reflection of light on static geometry is simulated. Light sources are allowed to be dynamic. Virtual point lights (VPLs) are used to simulate the reflection of light by surfaces. Their contribution to the final...
