Box3D exposes a C API and shares a nearly identical architecture to Box2D. Development was motivated by issues with Unreal Engine's native physics, and the codebase is partly derived from 'Rubikon-Lite', the physics engine behind Half-Life: Alyx. The project is currently in alpha (v0.1.0) but has already seen early adoption by a few games and game engines. ## Full article daily.dev links to this article rather than hosting it.
