Mip-Splatting: Anti-Aliased 3D Gaussian Splatting

Mip-Splatting targets a critical weakness of vanilla 3DGS during spatial roaming: the absence of anti-aliasing. Under the default framework, changing focal length or viewing the scene from far away breaks the image into noise and blocky dilation due to sampling-rate mismatch. The team brings classic signal processing theory into Gaussian rendering, designing a 2D optical low-pass filter that dynamically limits the on-screen frequency response of each Gaussian based on camera distance — preserving visual coherence under any push-pull motion without requiring a pre-trained multi-scale pyramid.
