TetSphere Splatting: Representing High-Quality Geometry with Lagrangian Volumetric Meshes

Lagrangian (TetSphere Splatting) Eulerian Ground Truth Reconstructed Shape Input Image Reconstructed Shape "A bear dressed in medieval armor" "A recliner chair" (a) (b) (c) (d) Figure 1: (a) Eulerian vs. Lagrangian geometry representations: Compared to Eulerian methods that rely on a fixed grid, TetSphere splatting, a Lagrangian method, uses a set of volumetric tetrahedral spheres that deform to represent the geometry. TetSphere splatting supports applications such as reconstruction, image-to-3D, and text-to-3D generation (b-d).
