PyPCSE

Description

PyPCSE is a Python library that provides tools for processing point clouds of symmetrical objects using the Point Cloud Spatial Expansion (PCSE) method. The transformation of a point cloud structure begins with identifying and adopting a symmetry element, which serves as the reference for the spatial expansion. The input data consists of point clouds in ASCII format.

The PyPCSE library includes algorithms for three PCSE method variants:

Cylindrical
Spherical
Ellipsoidal

Detailed descriptions of the PCSE method algorithms can be found in the following publications:
