polymesh 0.0.23

A Python package to build, manipulate and analyze polygonal meshes.

PolyMesh - A Python Library for Polygonal Meshes

Warning PolyMesh is in the early stages of it's lifetime, and some concepts may change in the future. If you seek long-term stability, wait until version 1.0, which is planned to be released if the core concepts all seem to sit and the documentation covers all major concepts.

The PolyMesh library aims to provide the tools to build and analyse poligonal meshes with complex topologies. Meshes can be built like a dictionary, using arbitarily nested layouts and then be translated to other formats including VTK and PyVista. For plotting, there is also support for K3D, Matplotlib and Plotly.

The data model is built around Awkward, which makes it possible to attach nested, variable-sized data to the points or the cells in a mesh, also providing interfaces to other popular libraries like Pandas or PyArrow. Implementations are fast as implementations rely on the vector math capabilities of NumPy, while other computationally sensitive calculations are JIT-compiled using Numba.

Here and there we also use NetworkX, SciPy, SymPy and scikit-learn.
