## What it is
NVIDIA PhysX SDK, a real-time physics simulation engine for games, robotics, and simulation, plus Omniverse PhysX extensions and the ovphysx C API with Python bindings for USD physics. It supports rigid body dynamics, collision detection, and GPU-accelerated simulation.

## Use cases
- simulate rigid body physics in a game engine
- run GPU-accelerated physics for robotics simulation in Isaac Sim
- add collision detection and dynamics to a 3D application
- simulate USD physics scenes from Python with tensor interop
- integrate a production-grade physics SDK into a C++ project

## When to choose
- you need a mature, industry-standard real-time physics engine
- you are building on NVIDIA Omniverse, Isaac Sim, or USD-based workflows
- you need GPU-accelerated physics simulation

## When to avoid
- you need only simple 2D physics (consider Box2D)
- you want a lightweight pure-Python physics library
- you cannot accept NVIDIA-specific SDK dependencies

## Facets
- artifact type: library
- maturity: stable
- function: simulation, graphics, game-engine, sdk
- domain: simulation, robotics, graphics
- platform: cpp, python, cross-platform
- tags: physics-engine, rigid-body-dynamics, usd-physics, nvidia, isaac-sim, dlpack, game-development, gpu
