## Features
* Collision detection and distance computation with GJK.
* Calculation of penetration depth with EPA.
* Collision detection and calculation of penetration depth with MPR.
* Various specific distance calculations for points, lines, line segments,
planes, triangles, rectangles, circles, disks, boxes, cylinders, ellipsoids,
...
* Broad phase collision detection with bounding volume hierarchy (AABB tree).
* Self-collision detection for robots.
* Contact wrench computation with hydroelastic contact model (pressure field
model).
## Dependencies
distance3d relies on numba to speed up computations. numba in its latest
version requires at least Python 3.7 and NumPy 1.18. See [here](
https://numba.readthedocs.io/en/stable/user/installing.html#compatibility)
for current requirements. Required Python libraries will automatically be
installed during installation of distance3d.
## Installation
Install the package with
pip install -e .
or from PyPI with
pip install distance3d
## Unit Tests
Install dependencies with
pip install -e .[test]
Run unit tests with
NUMBA_DISABLE_JIT=1 pytest
You will find the coverage report in `htmlcov/index.html`.
## API Documentation
Install dependencies with
pip install -e .[doc]
Build API documentation with
cd doc
make html
You will find the documentation in `doc/build/html/index.html`.
## Licenses
These implementations are mostly based on

The original GJK algorithm is a translation to Python of the translation to C of
the original Fortran implementation. The C implementation is from Diego Ruspini.

Some features related to the GJK algorithm have been inspired by
[Bullet](https://github.com/bulletphysics/bullet3/) (zlib license) and are
marked as such in the source code.
The EPA algorithm is adapted from

A GJK intersection test and the MPR algorithm are based on libccd (for details,
