Voxels solve Gaussian Splat collision detection

Using voxelization as a geometric proxy bridges the gap between high-fidelity 3D Gaussian Splats and standard physics engines. This technique makes 3DGS a viable option for interactive gaming and virtual reality, rather than just a visualization tool.

• –Sparse voxel octrees represent occupied space efficiently, enabling fast raycasts and collision queries without the performance overhead of dense meshes
• –Tooling like SuperSplat automates this conversion process directly in the browser, making the workflow accessible to web developers
• –While it does not support dynamic deformation yet, static collision grids are sufficient for walking, climbing, and basic environmental interaction
• –Game developers can now combine photorealistic Gaussian Splat visuals with standard physics colliders
