Erin Catto, the creator of the Box2D project, announced the creation of a new physics simulation engine Box3D, which is a fork of Box2D with an identical architecture, but redesigned and expanded for use in 3D games. The project's code is written in C and is distributed under the MIT license. Builds for Linux, Windows, and macOS are supported. <\/p>\n

The Box3D engine was developed by the studio Kintsugiyama for the new 3D shooter The Legend of California, in which Erin is involved. The game uses the Unreal Engine, but the developers were not satisfied with the built-in physics engine Chaos. Issues arose with the lack of accounting for gyroscopic torque (thin objects rotated unnaturally long), continuous collision detection (unrealistic behavior of falling trees), and low performance when processing hundreds of thousands of objects. <\/p>\n

Initially, the plan was to solve the problems by creating a fork of the Jolt physics engine, but then, at the suggestion of the creator of the Rubikon engine, involved in Half-Life, a simplified version of Rubikon-Lite was taken as the basis, which was reworked using code and optimizations from Box2D to combine the existing 3D capabilities with the developments from the Box2D engine. As a result, almost all APIs, data structures, and algorithms in Rubikon-Lite were replaced with code from Box2D, and only the algorithms for constructing convex hulls and processing 3D collisions remained from Rubikon-Lite. The resulting engine was decided to be published as a separate open project Box3D with the consent of the author of Rubikon-Lite and Kintsugiyama. <\/p>\n

The first release of Box3D 0.1 has been published, noted as having alpha quality. The main planned functionality is implemented, but documentation and testing require further refinement. In addition to the game The Legend of California, the new engine is already utilized in the s&box gaming platform, the open game engine Esoterica, and the multiplayer space game Space Game, designed for 1000 players. <\/p>\n

For 3D games in the new engine, features have been added such as collision calculations with polygonal meshes and height maps used for terrain generation, enabling realistic effects of falling trees on voxel surfaces in the game The Legend of California. Support for pre-calculated (baked) composite collisions, composed of several simple shapes, has significantly reduced resource consumption when simulating collisions of a vast number of typical small objects. <\/p>\n

Among the features transferred to Box3D that were previously available in Box2D: <\/p>\n
