Summary on Grant Application Form
The virtual light field (VLF) is an approach to computer graphics that supports constant-time walkthrough of globally illuminated scenes. It is an extension of the light field image-based rendering approach with a number of advantages. VLF computes an approximate solution to the rendering equation without recourse to another rendering system -radiance values are computed within the system itself. It allows arbitrary walkthrough rather than being restricted to a convex hull around the scene. It provides a relatively rapid solution to the global illumination problem. It supports in principle real-time walkthrough for scenes where there is a mix of specular and diffusely reflecting surfaces. The current proposal is to put exploratory work already carried out onto a firm foundation, to carry out research into a new compression based architecture for the VLF, and to explore the problem of dynamic changes within a light field approach.
