    Use Cases & Benefits

    • Provides a portable C17 3D physics engine optimized for games with robust collision detection and physics simulation features.
    • Delivers high performance through data-oriented design, multithreading, SIMD optimizations, and cross-platform determinism.
    • Use for integrating realistic rigid body physics and collision handling in cross-platform 3D game development projects.
    • Use for building simulation tools requiring continuous collision detection and complex joint constraints in C environments.
    • Use for creating physics-based interactive demos or educational software leveraging its extensive sample applications and GUI.
