Computer Graphics

Computer Graphics is the research field that tries to replicate the world around us using Computer Science. It is concerned with modelling reality and image synthesis from virtual 3D scenes. It can be seen as the opposite of Computer Vision.

Radiance Caching for efficient Global Illumination Computation

Radiance Caching is a ray tracing-based method for accelerated global illumination computation in scenes with low-frequency glossy BRDFs. The method is based on sparse sampling, caching, and interpolating radiance on glossy surfaces. In particular we extend the irradiance caching scheme proposed by Ward et al. in 1988 to cache and interpolate directional incoming radiance instead of irradiance. The incoming radiance at a point is represented by a vector of coefficients with respect to a spherical or hemispherical basis
