Bullet Physics SDK is a C++ library providing real-time collision detection and rigid/soft body multi-physics simulation, with Python bindings via PyBullet. It is widely used in games, VR, visual effects, robotics, and reinforcement learning research.

Use cases

• add physics simulation to a 3D game engine
• simulate robots with URDF models for robotics research
• train reinforcement learning agents in physics-based environments
• simulate rigid and soft body dynamics in real time
• run collision detection on the GPU with OpenCL
• generate synthetic datasets for machine learning with PyBullet

When to choose

• you need a mature, permissively licensed (zlib) real-time physics engine
• you want Python bindings for robotics or RL simulation
• you need cross-platform C++ physics with optional GPU acceleration

When to avoid

• you need a highly accurate offline/industrial FEA solver rather than real-time physics
• you require extensive commercial support or active issue-tracker assistance
• you need modern C++ standards beyond C++03 compatibility
