Development of Arclight, a Global Illumination Renderer for the creation of realistic lightmap textures

Arclight, a global illumination lightmap tool based on a texture-space modification of the Photon Mapping algorithm, is developed. A means of achieving distortion free lightmapping is devised by reversing the perspective correct texture transform. Unbiased Monte-Carlo and biased Quasi Monte-Carlo methods are used for evaluation of the General Rendering Equation. The application achieves computationally efficient irradiancecaching by development of a novel texture-space approach, and elegantly solves the traditional problem of edge artifacts through a novel modification of the OGSS anti-aliasing algorithm.
