E3DGS: Unified Geometric-Photometric Equivariance for 3D Gaussian Splatting via Color-as-Geometry Embedding

arXiv 2026 22.1 method

TLDR

Proposes E3DGS, an SE(3)-equivariant 3D Gaussian Splatting that unifies geometry and photometry via a matrix embedding for consistent world modeling.

Reasoning

The paper presents a novel theoretical framework to achieve strict SE(3) equivariance in 3D Gaussian Splatting by reformulating SH coefficients as geometric tensors, which is a strong contribution. However, the limitation to SH degrees ≤2 and the incomplete evaluation description (cut off) are weaknesses.
