Universidad de Zaragoza Progressive Transient Photon Beams 2019 Access copy available to the general public Unrestricted In this work, we introduce a novel algorithm for transient rendering in participating media. Our method is consistent, robust and is able to generate animations of time-resolved light transport featuring complex caustic light paths in media. We base our method on the observation that the spatial continuity provides an increased coverage of the temporal domain, and generalize photon beams to transient-state. We extend stead-state photon beam radiance estimates to include the temporal domain. Then, we develop a progressive variant of our approach which provably converges to the correct solution using finite memory by averaging independent realizations of the estimates with progressively reduced kernel bandwidths. We derive the optimal convergence rates accounting for space and time kernels, and demonstrate our method against previous consistent transient rendering methods for participating media. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.116 2019 COMPUTER SCIENCE, SOFTWARE ENGINEERING 38 / 108 = 0.352 2019 Q2 T2 1.246 2019 Computer Networks and Communications 2019 Q1 Computer Graphics and Computer-Aided Design 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0003-4833-8732 Guillén, I.
