From Particles to Fields: Reframing Photon Mapping with Continuous Gaussian Photon Fields

Abstract:
Accurately modeling light transport is essential for realistic image synthesis. Photon mapping provides physically grounded estimates of complex global illumination effects, such as caustics and specular-diffuse interactions. However, its per-view radiance estimation remains computationally inefficient when rendering multiple views of the same scene. This inefficiency arises from independent photon tracing and stochastic kernel estimation at each viewpoint, leading to redundant computation.

To accelerate multi-view rendering, we reformulate photon mapping as a continuous and reusable radiance function. Specifically, we introduce the Gaussian Photon Field (GPF), a learnable representation that encodes photon distributions as anisotropic 3D Gaussian primitives, parameterized by position, rotation, scale, and spectrum.

GPF is initialized from physically traced photons in the first SPPM iteration and optimized using multi-view supervision of final radiance, distilling photon-based light transport into a continuous field. Once trained, the field enables differentiable radiance evaluation along camera rays without repeated photon tracing or iterative refinement.

Extensive experiments on scenes with complex light transport, such as caustics and specular-diffuse interactions, demonstrate that GPF attains photon-level accuracy while reducing computation by orders of magnitude, unifying the physical rigor of photon-based rendering with the efficiency of neural scene representations.

I don't know if things have changed

But every time I told my dad (a retired cardiologist) about doing preventive MRIs and body scans etc

He said "yes Piet with any scan, you will find lots of stuff that looks malign (bad) but is mostly benign (good), but you're unsure so you start cutting in the body, doing invasive stuff, doing treatment and that's how you actually make someone sick who was fine before"

An example would be prostate cancer which apparently most men have latent cancer cells of anyway after age 50 and it's slowly growing but doesn't mean it will kill them

I'd love to hear counters to this though as I want to be a believer in preventative medicine, and do blood work and checkups regularly too

Incredibly pitiful
Few Russian (at least ethnic Russian) libs are this debased, “I hope we get conquered by NATO” is mostly a caricature from Ziggers
