500 Lines or Less A 3D Modeller

This article introduces the core principles of computer-aided design (CAD) software, explaining that CAD tools require three essential components: a data structure to represent 3D objects, a method to display them on 2D screens, and a way for users to interact with and modify designs. The author outlines how these fundamental features enable creators to design buildings, video game art, and other objects before physical construction, and proposes implementing a functional 3D modeller in 500 lines of Python.
