### Anti aliasing ### 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: We added the EWA Filter from [Mip Splatting](https://niujinshuchong.github.io/mip-splatting/) in our codebase to remove aliasing. It is disabled by default but you can enable it by adding `--antialiasing` when training on a scene using `train.py` or rendering using `render.py`.
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 .
```
