Uh, I looked and tried the code, it is incredible simple. It may be worth trying even if people where complaining of regular Sobol patterns ... I don't want even start to think what they will say about this.kintuX wrote: ↑Sat Feb 23, 2019 2:51 pm The Unreasonable Effectiveness of Quasirandom Sequences

Abstract 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.
Was blown away myself... amazing to see how photons travel, often i try to imagine how it would look expanded (visible+IR+UV) or full EM spectrum then i remember it is what we "see" or rather experience... light and excess Energy materialized, just so damn fast only rare can imagine interactivity of it all. Ever flowing.
