# Scientific Python Geometric Algorithms Library

## scikit-geometry

The scikit-geometry package contains a whole lot of geometric algorithms. For the moment, scikit-geometry derives most of it’s functionality from the mature and stable Computational Geometry Algorithms Library (CGAL) package, a collection of geometric algorithms written in C++. Basic Geometric Types

We aim to cleanly encapsulate the important building blocks of a geometric library. As such we have implementations for the basic geometric types:

`Point2`

,`Point3`

`Segment2`

,`Ray2`

,`Line2`

,`Segment3`

,`Ray3`

,`Line3`

`Vector2`

,`Vector3`

`Circle2`

`IsoRectangle2`

,`Bbox2`

`Plane3`

,`Triangle3`

`Polyhedron3`

All sorts of operations can be performed with these basic building blocks. For example, one can construct a new segment from two points, then test against intersection with another segment, or a line.

```
import skgeom as sg
a = sg.Point2(5, 3)
b = sg.Point2(10, 8)
print(a, b)
>>> PointC2(5, 3), PointC2(10, 8)
```

Now we can create a vector from two points by subtracting one from another.

```
v = a - b
print(v)
>>> VectorC2(-5, -5)
```

Or a segment between two points, where a is the source and b the target.

```
s = sg.Segment2(a, b)
print(s)
>>> Segment_2(PointC2(5, 3), PointC2(10, 8))
```

## Documentation

The docs are hosted on github: https://scikit-geometry.github.io/scikit-geometry

It is built from Jupyter notebooks that can be found under the `/docs`

subdirectory.
