HETOOL: A Half-Edge Topological Object-Oriented Library for generic 2-D geometric modeling

An object-oriented architecture of a topological data structure that allows high-level interactive two-dimensional (2-D) geometric modeling, called HETOOL, is introduced in this paper. The implementation based on the well-known half-edge for 2-manifold solids, adapted here to deal efficiently with general 2-D models and planar subdivisions, often employed science engineering problems. HETOOL was implemented Python. developed package presents dynamic performs automatic sewing modeled elements. library offers many features facilities user, allowing use even without user knowing concepts involved implementing structure. In addition, flexibility configuring new attributes, enabling creation these elements fast straightforward way from file JSON format. This versatility creating attributes application solve several problems present scientific world.
