Neural Emission Fields: Real-Time Rendering of Pre-integrated Neural Emitters
ssh4net · x · 2026-10-07
Neural Emission Fields (NEF), from Graz University of Technology and Huawei (Switzerland/Austria), tackles a persistent bottleneck in real-time rendering: direct illumination from complex emitters — those with occluding housings, high-polygon emissive meshes, spatially varying emission, or deformable assemblies.
Current approaches fall short: analytical methods only handle simple emitter geometry, sampling-based estimators need high sampling budgets to be noise-free, and proxy representations still require runtime integration over outgoing radiance.
NEF pre-integrates emission into a neural representation, eliminating runtime integration and enabling real-time rendering of complex emitters.
