Ensemble metropolis light transport
Bashford-Rogers, Thomas; Santos, Luís Paulo; Marnerides, Demetris; Debattista, KurtThis article proposes a Markov Chain Monte Carlo (MCMC) rendering algorithm based on a family of guided transition kernels. The kernels exploit properties of ensembles of light transport paths, which are distributed according to the lighting in the scene, and utilize this information to make informed decisions for guiding local path sampling. Critically, our approach does not require caching distributions in wo...
A quantum algorithm for ray casting using an orthographic camera
Alves, Carolina; Santos, Luís Paulo; Bashford-Rogers, ThomasQuantum computing has the potential to provide solutions to many problems which are challenging or out of reach of classical computers. There are several problems in rendering which are amenable to being solved in quantum computers, but these have yet to be demonstrated in practice. This work takes a first step in applying quantum computing to one of the most fundamental operations in rendering: ray casting. Th...
