SSR-GS: Advanced Glossy Surface Reconstruction for Digital Twins & AR/VR
Despite advances in 3D Gaussian Splatting (3DGS) for novel view synthesis, accurately reconstructing glossy surfaces under complex illumination, especially with strong specular reflections and multi-surface interreflections, remains a significant challenge, leading to geometric artifacts and surface collapse. Our SSR-GS framework precisely addresses this by decoupling diffuse and specular components, introducing a Mip-Cubemap for direct specular reflections and an IndiASG module for indirect reflections. Coupled with Visual Geometry Priors (VGP) to stabilize geometry, SSR-GS achieves state-of-the-art high-fidelity glossy surface reconstruction, enabling unprecedented realism for demanding enterprise applications.

Mip-Cubemap Environment Representation
The Mip-Cubemap environment representation models direct specular reflections by employing a roughness-aware environment map query. This approach utilizes a physically motivated normal distribution function (NDF) prefilter approximation, reducing complex hemispherical integration to a single Mip-Cubemap lookup. By querying a mipmap hierarchy, it handles varying surface roughness, with higher mip levels corresponding to blurrier representations for broader specular lobes. This method significantly improves multi-scale environment sampling and ensures more accurate, roughness-aware reflection rendering, while avoiding projection distortion.
IndiASG for Indirect Specular Reflection Modeling
The IndiASG module (Indirect Anisotropic Spherical Gaussian) addresses the challenge of inaccurate geometry caused by multi-surface indirect illumination. It is a compact, learning-based local light field representation that models indirect specular reflection using a fixed set of anisotropic spherical Gaussian lobes over the upper hemisphere. A neural predictor estimates per-lobe radiometric parameters, enabling physically consistent indirect specular modeling. This explicit modeling of indirect specular reflections enhances geometric stability and allows Gaussians to capture multi-view consistent geometry more effectively.
Visual Geometry Priors (VGP)
The Visual Geometry Priors (VGP) module enhances geometric fidelity and cross-view consistency by coupling a visual prior (VP) with geometry priors (GP). The VP, implemented via a reflection score (RS), identifies and suppresses reflection-dominated regions to downweight their photometric loss contribution, reducing adverse view-dependent appearance impacts. The GP applies VGGT-inferred depth and transformed normal constraints, regularizing geometry and enabling stable optimization. This synergistic approach ensures higher-quality reconstruction, particularly under complex reflections.
