A Python Geometric Algorithms Library

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))
