Faithful Contouring: No SDF, No Watertight, 1024 Cubed Voxelization

Faithful Contouring introduces a new 3D voxelization method that bypasses traditional SDF and Marching Cubes approaches, enabling 1024-cubed voxelization in roughly 1 second on a single GPU. The technique encodes triangle meshes directly into sparse voxel tokens while preserving topology, and was accepted as a CVPR 2026 oral presentation.
