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. 000087832 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000087832 590__ $$a2.116$$b2019 000087832 591__ $$aCOMPUTER SCIENCE, SOFTWARE ENGINEERING$$b38 / 108 = 0.352$$c2019$$dQ2$$eT2 000087832 592__ $$a1.246$$b2019 000087832 593__ $$aComputer Networks and Communications$$c2019$$dQ1 000087832 593__ $$aComputer Graphics and Computer-Aided Design$$c2019$$dQ1 000087832 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000087832 700__ $$0(orcid)0000-0003-4833-8732$$aGuillén, I.$$uUniversidad de Zaragoza 000087832 700__ $$aJarosz, W. 000087832 700__ $$0(orcid)0000-0002-7503-7022$$aGutierrez, D.$$uUniversidad de Zaragoza 000087832 700__ $$0(orcid)0000-0001-9000-0466$$aJarabo, A.$$uUniversidad de Zaragoza 000087832 7102_ $$15007$$2570$$aUniversidad de Zaragoza$$bDpto.
