EAG-PT: Emission-Aware Gaussians and Path Tracing for Indoor Scene Reconstruction and Editing
Contributions:
โข Emission-aware scene decomposition. We explicitly separate emissive light sources from non-emissive geometry using 2D emission masks, fixing previous inappropriate radiant scene modeling for further editing.
โข Inverse recovery of radiance and material properties. We recover emitter radiance and spatially varying surface reflectance for non-emissive components via differentiable rendering from multi-view observations.
โข Physically based light transport after editing. We apply path tracing to edited scenes to re-evaluate multi-bounce global illumination, avoiding reliance on obsolete radiance cache at capture time.
โข Unified 2D Gaussian representation. We adopt 2D Gaussians as a single scene representation that supports ray intersection, light transport, material modeling, and radiance caching, enabling efficient reconstruction and rendering.
