## What ``ARTIST`` can do for you

The ``ARTIST`` package provides an implementation of a differentiable ray tracer using the `PyTorch` machine-learning
framework in `Python`. Leveraging automatic differentiation and GPU computation, it facilitates the optimization of
heliostats, towers, and camera parameters within a solar field by combining gradient-based optimization methods with
smooth parametric descriptions of heliostats.

**Our contributions include:**

- **Efficient heliostat calibration:** We develop a parallelized geometric kinematic model that enables efficient
    calibration via either ray tracing-based or motor position data. This offers a flexible and robust approach to
    heliostat calibration.

- **Surface reconstruction and flux density prediction:** Leveraging learning Non-Uniform Rational B-Splines (NURBS),
  `ARTIST` reconstructs heliostat surfaces accurately using calibration images commonly available in solar thermal power plants.
  Thus, we can achieve sub-millimeter accuracy in mirror reconstruction from focal spot images, contributing to improved
  operational safety and efficiency. The reconstructed surfaces can be used for predicting unique heliostat flux densities
  with state-of-the-art accuracy. Check out [this paper](https://doi.org/10.21203/rs.3.rs-2554998/v1) for more details.

- **Immediate deployment**: `ARTIST` enables deployment at the beginning of a solar thermal plant's operation,
  allowing for in situ calibration and subsequent improvements in energy efficiencies and cost reductions.

- **Optimized flux density:** ``ARTIST`` enables flux density optimization across an entire heliostat field by optimizing
  the motor positions of all heliostats to distribute the flux optimally over the receiver.


## Installation
We heavily recommend installing the `ARTIST` package in a dedicated `Python3.10+` virtual environment. You can
install ``ARTIST`` directly from the GitHub repository via:
```bash
pip install artist
```
Alternatively, you can install ``ARTIST`` locally. To achieve this, there are two steps you need to follow:
1. Clone the `ARTIST` repository:
   ```bash
   git clone https://github.com/ARTIST-Association/ARTIST.git
   ```
2. Install the package from the main branch. There are multiple installation options available:
   - Install basic dependencies: ``pip install .``
   - Install with optional dependencies to run the tutorials:  ``pip install ."[tutorials]"``
   - Install an editable version with developer dependencies: ``pip install -e ."[dev]"``

## Structure
The ``ARTIST`` repository is structured as shown below:
```
