 ### Anti aliasing
-We added the EWA Filter from [Mip Splatting](https://niujinshuchong.github.io/mip-splatting/) in our codebase to remove aliasing. Antialiasing is enabled by default, to disable it please do the following:
-1. Comment out `#define DGR_FIX_AA` in `submodules/diff-gaussian-rasterization/cuda_rasterizer/auxiliary.h`.
-2. Re-install the rasterizer in your environment: 
-    ```
-    pip uninstall diff-gaussian-rasterization
-    cd submodules/diff-gaussian-rasterization
-    rm -r build
-    pip install .
-    ```
