DySurface: Consistent 4D Surface Reconstruction via Bridging Explicit Gaussians and Implicit Functions
DySurface reconstructs dynamic 3D surfaces consistently by merging explicit 3D Gaussian Splatting (GS) with implicit Signed Distance Functions (SDFs). It solves geometric inconsistencies in temporal reconstruction by linking how Gaussians move forward in time with how the continuous SDF field deforms backward, resulting in high-fidelity, stable meshes.
