Path-Tracing for light transport simulation

Abstract

Photorealistic rendering algorithms are used in various applications, like movies, games, and CAD software. A class of algorithms that is extremely important for this end is the Ray-tracing algorithms, which uses geometric optics concepts to simulate light-transport in virtual scenes. The Path-tracing algorithm proposed by (KAJIYA, 1986) was devised as an improvement to Ray-tracing, allowing the simulation of more global illumination effects with lower computational cost, providing a framework for accurate light physics simulation, and will be the main focus of this work, directed at implementing the Path-tracing algorithm, building a comprehensive theoretical framework and comparing results with consolidated rendering solutions.
