***
## Installation:
It is recommended to install directly from the Python Package Index (PyPI):
```
pip install ceres-raytracer
```
***
## Building from Source:
```
git clone https://github.com/ceres-navigation/ceres-raytracer.git
pip install .
```
[sphinx](https://www.sphinx-doc.org/en/master/) is used to build documentation for the python API. To install `sphinx`, simply use:
```
sudo apt-get install python3-sphinx
pip install sphinx-autodoc-typehints sphinx-toolbox sphinx-licenseinfo sphinx-rtd-theme
```
Once `sphinx` is installed, you can build the documentation on Linux systems by running:
```
cd doc
make html
```
***
## Demos:
After installing `ceres-raytracer`, simply clone the [ceres-raytracer-demos](https://github.com/ceres-navigation/ceres-raytracer-demos):
```
git clone https://github.com/ceres-navigation/ceres-raytracer-demos.git
```
and run any of the included `.py` example files:
### cornel_box.py
This demo script demonstrates multi-bounce path tracing using the traditional cornell box scene. It additionally shows how to render depth, instances and normal passes:
### comet67p.py
This demo script demonstrates how to use CRT's SPICE support, and rendering in a body fixed frame (allowing for the BVH to be cached and therefore overall faster render times):

### madmann91's Modern C++ BVH Construction and Traversal Library
This project utilizes a BVH construction and traversal library built by [madmann91](https://github.com/madmann91). While we have made some modifications to their implementation, their work forms most of the basis of the bounding volume hierarchy used in this project. Their originally source code can be found in the [bvh repository](https://github.com/madmann91/bvh)
### National Science Foundation Graduate Research Fellowship
This material is based upon work supported by the [National Science Foundation Graduate Research Fellowship](https://www.nsfgrfp.org/) under Grant No. 2020305048. NSF GRFP gave Chris Gnam the flexibility and resources required to complete his research in spacecraft navigation, and this project is meant to serve as an open source implementation of his dissertation.
