Definition
Light transport describes how the light emitted from light sources propagates into a 3D scene and bounces between object surfaces. The light transport in a scene can also be presented by a reflectance field that directly encodes the mapping between the incident light field to the outgoing light field of the scene caused by the light transport.
Background
The physical process of light transport in a 3D scene has been well studied in computer graphics since 1980s. In theory, the light transport in a scene can be formulated by the rendering equation [5]. In practice, simulating the light transport in a 3D scene (i.e., global illumination effects) is the essential task of various rendering techniques in computer graphics. To this end, a set of global illumination algorithms, such as Monte Carlo ray tracing,...
