You need a Windows PC (preferably with Windows 7 OS or higher) with Microsoft Visual C++ 2010 Express compiler installed on it. You can download VC++ 2010 Express for free from http://www.microsoft.com. You also need to download Nvidia PhysX SDK 3.3.0 from https://developer.nvidia.com/physx-downloads, which requires you to register for the Nvidia Developer Program. You may also want to download the freeglut library for Windows, which is freely available at http://freeglut.sourceforge.net. This library is used in the example code to render the PhysX components.
