Jolt Physics is a multicore-friendly rigid body physics and collision detection library written in C++. It is designed for games and VR applications and is used in shipped titles like Horizon Forbidden West and Death Stranding 2.
Use cases
- simulate rigid body physics in a game engine
- collision detection for games and VR
- run physics queries in parallel with the simulation on multiple threads
- simulate ragdolls and character physics
- stream physics bodies in and out of a live simulation on background threads
When to choose
- you need a fast, production-proven physics engine for a game or VR title
- your engine is multithreaded and you need concurrent collision queries and background body streaming
- you want a permissively licensed (MIT) C++ physics library
When to avoid
- you need soft-body or fluid simulation rather than rigid bodies
- you want a high-level engine with built-in rendering or editor tooling
- your project is not in C++ or lacks bindings for your language
