Deep Dive
The work argues that 3D Gaussians are multi-view inconsistent for thin surfaces. 2DGS represents oriented planar Gaussian disks and uses ray-splat intersection for perspective-correct rendering, augmented by depth distortion and normal consistency losses. It targets noise-free meshes and stable normals while keeping competitive appearance and real-time splatting. The project site and repository ship reference code and geometry comparisons.
What we learn
- 01
Explicit surface primitives with ray intersection directly reduce multi-view depth inconsistency.
- 02
Pairing geometric regularizers with photometric losses is a recurring recipe for exportable meshes from neural fields.
