abspy - abspy v0.2.1

The first release for abspy, a Python tool for 3D adaptive binary space partitioning and beyond. It offers the following features:

• Manipulation of planar primitives detected from point clouds
• Linear cell complex creation with adaptive binary space partitioning (a-BSP)
• Dynamic BSP-tree (NetworkX graph) updated locally upon insertion of primitives
• Support of polygonal surface reconstruction from graph cuts
• Compatible data structure with Easy3D on point clouds, primitives, cell complexes and surfaces
• Robust Boolean spatial operations underpinned by the rational ring from SageMath's exact kernel

abspy can also be installed as a package from PyPI: pip install abspy
