Multiplexed Metropolis Light Transport

Thesis Multiplexed Metropolis Light Transport


Multiplexed Metropolis light transport (MMLT) proposed by Hachisuka et al. (2014) at SIGGRAPH is a global illumination rendering algorithm which can efficiently solve indirect illumination issues. The key feature of MMLT is that the implementation of this algorithm is not difficult compared to other sophisticated Metropolis sampling rendering algorithms, and its performance is still effective. In this project, MMLT has been successfully implemented and extended from my rendering engine which was written for previous assignments. The quality of the final rendered images demonstrates the efficiency of MMLT for solving indirect illumination problems.
