Real-Time Physics Simulation with Dynamic Mesh-Gaussian Reconstructions
Researchers have explored integrating dynamic 3D reconstructions with physics simulations, a task complicated by the need for fixed mesh topology in simulations. They propose a dual-representation framework that uses fixed-topology meshes for physics calculations and Gaussian splatting for rendering, achieving a speedup through runtime vertex buffer updates. However, their evaluation showed that topology conversion methods led to significant geometric degradation, suggesting that high-quality reconstruction and physics-compatible topology are distinct objectives.
