Definitions

Many-light rendering is a class of efficient image synthesis algorithms that try to render a scene with a large number of light sources. These light sources can be real lights in the scene, or virtual point lights (VPLs) approximate light transportation of current lighting conditions.

Introduction

Full global illumination is considered the crown of rendering. Creating high fidelity global illumination efficiently is one of the most important topics in photo-realistic image synthesis. In order to calculate a high dimensional integration in the rendering equation proposed by Kajiya (1986), a huge amount of computational power is needed, which prevents the pure path-tracing group of methods from implementing in an interactive to real-time systems. In the other hand, such tracing algorithms are often not regular, which will cause workload balance problems or irregular memory access problems on parallel hardware architectures...
