… 3D Gaussians for surface reconstruction poses significant challenges due to the explicit and disconnected nature of 3D Gaussians.
… present Gaussian Opacity Fields (GOF), a novel approach for efficient, high-quality, and compact surface reconstruction in unbounded scenes.
… GOF is … from ray-tracing-based volume rendering of 3D Gaussians, enabling … geometry extraction from 3D Gaussians by identifying its levelset, without … Poisson reconstruction or TSDF fusion
… approximate the surface normal of Gaussians as the normal of the ray-Gaussian intersection plane, enabling the application of regularization that … enhances geometry.
… develop an efficient geometry extraction method utilizing marching tetrahedra, where the tetrahedral grids are induced from 3D Gaussians and thus adapt to the scene’s complexity.
… GOF surpasses existing 3DGS-based methods in surface reconstruction … compares favorably … or … outperforms, neural implicit methods in both quality and speed.
