## Introduction

Welcome to the NVIDIA PhysX SDK source code repository.

The NVIDIA PhysX SDK is a scalable multi-platform physics solution for CPUs and GPUs.  See [PhysX SDK on developer.nvidia.com](https://developer.nvidia.com/physx-sdk).

The [Release Notes](./CHANGELOG.md) contain updates pertaining to the latest version.

## User Guide and API Documentation

The user guide and API documentation are available on [GitHub Pages](https://nvidia-omniverse.github.io/PhysX/physx/index.html). Please create an [Issue](https://github.com/NVIDIA-Omniverse/PhysX/issues/) if you find a documentation issue.

## Quick Start Instructions

Platform specific environment and build information can be found in [documentation/platformreadme](./documentation/platformreadme).

To begin, clone this repository onto your local drive.  Then change directory to physx/, run ./generate_projects.[bat|sh] and follow on-screen prompts.  This will let you select a platform specific solution to build.  You can then build from the generated solution/make file in the platform- and configuration-specific folders in the ``compiler`` folder.

Note that the PhysX distribution downloads binary content, such as the PhysX GPU binaries, from Amazon CloudFront on demand, using the packman package manager.
