Realtime Global Illumination of Moving Fire Light Sources

Abstract

In this thesis, a new way to approximate the environmental lighting due to fire flicker using a procedurally generated radiance map is presented. This local dynamic radiance map is projected from the fire source through a cube texture outwards toward the surrounding environment. To achieve realistic results, we have chosen some global illumination algorithms that are needed to calculate the direct and indirect illumination of the fire source. In addition, a procedurally simulated GPU based fire is implemented to approximate the flames emitted from a torch.
