# Three Body Problem Visualization
We simulate the restricted Euler problem and visualize known orbits from literature.
The visualization is at [here](https://three-body-problem.vercel.app/).
## 1. Contributing
To contribute to this project, make a fork and,
```
git clone https://github.com//Three-Body-Problem.git
cd Three-Body-Problem
npm install
npm run dev
```
The physics components are located in `src/computation/cpp/` (the python version is also available, but takes significantly longer time to run). To run the simulation,
```
cd src/computation/cpp/
make
./simulation
```
Note that `num_output_steps` refer to the number of 0.01 units of time steps (not `dt` units of time steps). For more accurate simulation results, $\mathrm{d}t < 0.001$ is recommended. The results of the simulation are precomputed with `num_steps = 3600`, `dt = 0.00001` and stored in `public/position_files//`, where `` refers to the order of the symplectic integrator.
