Optix Splats
This repo contains code for a differentiable gaussian renderer that leverages ray-tracing and OIT techniques to render gaussian splatted scenes.
Setup and Compilation
First install Anaconda. Then create an environment from the repo yaml
conda env create -f environment.yml
Compilation
You first need to change the variable optix_root in setup.py to the path where optix is located on your machine.
You can build the extension with
python setup.py install
You can test the install is functional by running the test script
python test/render_test.py
Common Issues
You may have issues with pygame if on Ubuntu 22.04. To fix you need to delete the conda versions of libstdc++ so it falls back to your OS. You can find the path to the conda drivers by exposing the debug environment variable.
export LIBGL_DEBUG=verbose
And then going to the anaconda path and deleting libstdc++ (deleting the symlink works too)
