Our renderer is written in c++ and can be compiled to a python package by using pybind11. We already compiled two versions for python 3.9 (renderer.cpython-39-x86_64-linux-gnu.so) and python 3.10 (renderer.cpython-310-x86_64-linux-gnu.so), which means that if you are using python 3.9/3.10, you do not need to do anything.
If you are using a different python version or find that our renderer does not work on your machine, you can compile it from scratch by simply running the make command in this folder.
