Bake It Till You Make It: Ultrafast Spatial Texture-Atlas Splatting
Ultrafast Spatial Texture-Atlas Splatting is a new method for real-time 4K rendering that speeds up novel view synthesis by separating geometry from high-frequency textures. It models geometry with surfels and stores complex texture details in a compact, baked RGB texture atlas. This approach achieves up to fivefold speedup over 3D Gaussian Splatting while maintaining high visual quality.
