Mip-Splatting: Alias-free 3D Gaussian SRecently, 3D Gaussian Splatting has demonstrated impressive novel view synthesis results, reaching high fidelity and efficiency. However, strong artifacts can be observed when changing the sampling rate, e.g., by changing focal length or camera distance. We find that the source for this phenomenon can be attributed to the lack of 3D frequency constraints and the usage of a 2D dilation filter. To address this problem, we introduce a 3D smoothing filter which

3D高斯插值渲染无别名三维滤波器视图合成高频伪影消除三维频率约束

本文提出了一种名为3D平滑滤波器的创新方法，通过约束3D高斯基元的大小来消除在新颖视角合成中因焦距或相机距离变化而产生的高频伪影。同时，替代2D膨胀滤波器的2D Mip滤波器有效缓解了混叠和伪影问题，提升了合成效果。
