about

nx_photoreal_gfx_fetch.nx -- how AAA / NVIDIA graphics research reaches PHOTOREAL with NO generative AI. The non-gen pillars are PHYSICS (accurate light transport) + MEASUREMENT (scanned data): PBR microfacet BRDF (GGX/Cook-Torrance) · PATH TRACING + GI (pbrt / kajiya / Falcor / RTXGI/RTXDI/ReSTIR) · subsurface SCATTERING (diffusion profiles) · IMAGE-BASED LIGHTING (filament split-sum) · measured reflectance (Light Stage). Banks raw -> knowledge/research/pgfx_*.raw. expect_exit: 0
