It is now available on GitHub. Box3D repository You can think of Box3D as a fork of Box2D, extended with many features needed for 3D games. Some additions: Triangle mesh collision Height-field collision Baked compound collision The core architecture of Box3D remains almost identical to Box2D. C API All library source is C17 Sub-stepping solver Continuous collision Graph coloring for large islands Wide SIMD contact solver Multi-threading hooks Optional internal scheduler Large world support with doubles for position Recording and replay If you want to see Box3D in action, watch this video:
