Note: Currently this example only supports Linux/X11.
This application is neither complex nor optimized for performance. It is intended to showcase OpenXR and how it is to be used for a simple VR application.
It is split into two parts. main.c contains almost only the interaction with OpenXR.
The OpenGL rendering is contained as much as possible in glimpl.c so it does not clutter the main application.
Unless the OpenXR runtime is installed in the file system, the XR_RUNTIME_JSON variable has to be set for the loader to know where to look for the runtime and how the runtime is named
XR_RUNTIME_JSON=~/monado/build/openxr_monado-dev.json
then, you should be ready to run ./openxr-example.
If you want to use API layers that are not installed in the default path, set the variable XR_API_LAYER_PATH
XR_API_LAYER_PATH=/path/to/api_layers/
This will enable to loader to find api layers at this path and enumerate them with xrEnumerateApiLayerProperties()
API Layers can be enabled either with code or the loader can be told to enable an API layer with XR_ENABLE_API_LAYERS
XR_ENABLE_API_LAYERS=XR_APILAYER_LUNARG_core_validation
