Abstract
a) PermutoSDF b) Ours (7-Mesh) c) 3DGS d) Ours (7-Mesh) Figure 1. Our Volumetric Surfaces representation (b) consists of k lightweight, semi-transparent mesh shells that efficiently render fuzzy geometries with a limited number of samples (3 ≤ k ≤ 9) via rasterization. Our image quality surpasses that of surface-based methods (a) and approaches the quality of 3D Gaussian splatting (c). Unlike splatting methods, our sorting-free representation enables faster rendering, particularly on low-power or mobile graphics hardware. Project page: https://autonomousvision.github.io/volsurfs .
