Multi-Layer Alpha Tracing
(The Eurographics Association, 2020)
Rendering many transparent surfaces in real-time is still an open problem. We introduce two techniques for fast transparency rendering with ray tracing hardware, one being exact and the other being approximate but of high ...
Portal-Based Path Perturbation for Metropolis Light Transport
(The Eurographics Association, 2020)
Light transport simulation in scenes with difficult visibility still remains a challenging problem. Markov chain Monte Carlo (MCMC) rendering is often employed for such configurations. It generates a sequence of correlated ...
