PhysXbased

PhysXbased is a term used in software development to describe a project, component, or system that uses the NVIDIA PhysX physics engine to provide real-time physics simulation. It is not an official product name but a descriptor indicating reliance on PhysX.

PhysX is a middleware physics engine originally developed by Ageia and acquired by Nvidia in 2008. It offers rigid body dynamics, collision detection, joints, and various modules for more advanced effects such as cloth, soft bodies, and fluids in its different versions. A PhysXbased project typically uses the PhysX SDK and integration APIs to simulate gravity, collisions, forces, and constraints within a virtual environment.

Implementation and performance considerations: PhysX can run on CPU, and on supported Nvidia hardware it can leverage GPU acceleration. Projects described as PhysXbased may balance CPU and GPU workloads and may rely on engine plugins or custom wrappers to integrate PhysX with rendering, input, and gameplay logic.

Applications and scope: The term appears in game development, simulation, visualization, and research contexts where real-time physics matters. It signals a preference for physically grounded behavior rather than hard-coded heuristics. The designation is informal and may appear in code comments, documentation, or project READMEs to indicate reliance on NVIDIA PhysX.
