Box2D Announces Box3D, a New 3‑D Physics Engine

Box2D, the widely used 2‑D physics engine, has introduced a new project called Box3D. Box3D aims to bring the same simplicity and performance to three‑dimensional simulations. The announcement was posted on the official Box2D blog in June 2026. Developers can expect familiar APIs adapted for 3‑D environments. The engine targets game developers and real‑time applications that need robust physics. Source code and documentation are made available through the project’s website. The team plans to iterate on the engine based on community feedback. Early adopters are encouraged to experiment and contribute to its evolution.
