Easy3D vs FreeCAD

Easy3D is an open‑source library that provides a simple, efficient API for handling point clouds, meshes, and other 3D data structures. It supports both C++ and Python, making it easy to integrate into research prototypes or production pipelines. The library focuses on performance and ease of use, offering built‑in visualisation tools, file I/O for common formats, and utilities for geometry processing, all while keeping the dependency footprint minimal.

FreeCAD is a free and open-source 3D parametric modeler that allows users to create complex 3D models using a variety of tools and techniques. It is designed to be highly customizable and extensible, with a large community of users and developers contributing to its development.
