Resources of open 3D data and tools for the geospatial domaian
pyVista - 3D plotting and mesh analysis through a streamlined interface for the Visualization Toolkit (VTK).
Trimesh - Pure Python library for loading and using triangular meshes with an emphasis on watertight surfaces. The goal of the library is to provide a full featured and well tested Trimesh object which allows for easy manipulation and analysis, in the style of the Polygon object in the Shapely library.
Pymesh - A rapid prototyping platform focused on geometry processing.
Geometry3D - Geometry3D is a simple python computational geographics library written in python.
Open3D - Open-source library that supports rapid development of software that deals with 3D data. The Open3D frontend exposes a set of carefully selected data structures and algorithms in both C++ and Python. The backend is highly optimized and is set up for parallelization.
Libigl - A simple (C++) geometry processing library
meshplot - Plot 3D triangle meshes
Py3DViewer - Python library based on Numpy for fast prototyping of geometry processing algorithms.
cadquery - CadQuery is an intuitive, easy-to-use Python library for building parametric 3D CAD models.
PostGIS 3D functions - PostGIS Functions that support 3D geometries.
FreeCad - Open-source parametric 3D modeler made primarily to design real-life objects of any size.
