Abstract
Image-based lighting is widely used to represent real-world, complex lighting in recent years. Image-based lighting captures surrounding environment illumination as an environment map, and uses it for the illumination. Although realistic images can be rendered by using image-based lighting, the computational cost using image-based lighting can be prohibitive since rendering under image-based lighting requires the product integral of incident radiance, visibility function, BRDF over the hemisphere. This paper surveys the recent papers on fast rendering using image-based lighting.
