… the final gathering step of photon mapping to the graphics hardware (GPU). The CPU is only
responsible for generating new light paths and updating the unfiltered photon map. Thanks …

… We analyze their construction times as well as photon gathering performance. Volumetric
effects like fog and smoke are described and implemented in the renderer. Our suite of test …

… This means we can gather a maximum number of ≈ 60 photons per sampling point (we
cannot use the full 16 KByte of shared memory because CUDA uses part of it for kernel …

… photon mapping algorithm that runs entirely on the GPU. We have changed the data structure
for the photon map to a … This final gather approach is more expensive, although the cost for …

… Some approaches, such as photon mapping [Jensen 1996], … , the final gathering process
regards the photon map as a rough … Since the final gathering process is essentially the same as …

… density, we pre-compute the irradiance to speed-up the final gather stage. … , we perform
the entire set of computations on the GPU, and to achieve the best performance we utilize OptiX …

… a new GPU accelerated final gathering method … ton mapping in real-time for dynamic scenes
on commodity hardware. We will do this by exploiting the main idea behind photon mapping…

… neighbor’s output; CPU photon tracing and GPU radiance estimation tasks require the most
… We describe the pure photon mapping without final gathering. Final gathering is a variance …

… apply final gather to evaluate its incident irradiance using GPU-based photon mapping. We
… the scene on the GPU, and utilize it for ray tracing and photon mapping. These steps follow …
