Paper Abstract:
|
In this paper we present a novel real-time algorithm to compute the global illumination of scenes with dynamic geometry and arbitrarily complex dynamic illumination. We use a virtual point light (VPL) illumination model on the volume representation of the scene. Light is propagated in void space using an iterative diffusion approach. Unlike other dynamic VPL-based real-time approaches, our method handles occlusion (shadowing and masking) caused by the interference of geometry and is able to estimate diffuse inter-reflections from multiple light bounces. |
