PhysX 4.1.1

Important:

NVIDIA PhysX in EZ is no longer maintained. The code is currently still there, but most likely doesn't compile without errors anymore.

Link: https://github.com/NVIDIAGameWorks/PhysX

Compile switch: EZ_BUILD_PHYSX

NVIDIA PhysX is used to provide collision detection, physics simulation, character controllers and other interactions.

To build PhysX yourself:

  1. Checkout https://github.com/NVIDIAGameWorks/PhysX.git
  2. Goto physx/buildtools/presets/public and open all presets that you want to build and change or add
    <cmakeSwitch name="NV_USE_STATIC_WINCRT" value="False" comment="Use the statically linked windows CRT" />
    <cmakeSwitch name="NV_USE_DEBUG_WINCRT" value="True" comment="Use the debug version of the CRT" />
  3. Run physx/generate_projects.bat for every configuration you want to build
  4. Open physx/compiler/.../PhysXSDK.sln and compile CMakePredefinedTargets/INSTALL for both debug and release
  5. Uwp installs are missing two include folders: PhysX/include/cudamanager and PhysX/include/gpu so copy those from physx/include to physx/install/.../PhysX/include
  6. The content of the built configuration in physx/install is now ready to be consumed by ezEngine by pointing the advanced cmake var EZ_PHYSX_SDK to it.

Important:

Depending on how you use PhysX, you may need to acquire (buy) a license for it from NVIDIA.
