NAME

     hello_xr — A sample OpenXR application.

SYNOPSIS

     hello_xr [-h | --help]
     hello_xr -g | --graphics graphics_api [-ff | --formfactor form_factor]
              [-vc | --viewconfig view_config] [-bm | --blendmode blend_mode]
              [-s | --space space] [-v | --verbose]

DESCRIPTION

     hello_xr is a sample application written using the OpenXR API.

     The arguments are as follows:

     -h | --help
              Show brief usage instructions.

     g | --graphics graphics_api
              Required: specify the graphics API to use.  (Note that not that not all graphics
              APIs are necessarily available on all systems.)  The parameter graphics_api must be
              one of the following (case-insensitive):

              ‘D3D11’
                      Direct3D 11 (Windows-only)

              ‘D3D12’
                      Direct3D 12 (Windows-only)

              ‘OpenGLES’

              ‘OpenGL’

              ‘Vulkan’

     -ff | --formfactor form_factor
              Specify the form factor to use.  (Note that you need a suitable XR system and a
              runtime supporting a given form factor for it to work.)  The parameter form_factor
              must be one of the following (case-insensitive):

              ‘Hmd’   Head-mounted display (default)

              ‘Handheld’

     -vc | --viewconfig view_config
              Specify the view configuration to use.  (Note that you need a suitable XR system
              and a runtime supporting a given view configuration for it to work.)  The parameter
              view_config must be one of the following (case-insensitive):

              ‘Mono’

              ‘Stereo’
                      (default)

     -bm | --blendmode blend_mode
              Specify the environment blend mode to use.  (Note that you need a suitable XR
              system and a runtime supporting a given environment blend mode for it to work.)
              The parameter blend_mode must be one of the following (case-insensitive):

              ‘Opaque’

              ‘Additive’

              ‘AlphaBlend’

     -s | --space space
              Specify the space to use.  The parameter space must be one of the following (case-
              insensitive):

              ‘View’

              ‘Local’

              ‘Stage’

     -v | --verbose
              Enable verbose logging output from the hello_xr application itself.

EXIT STATUS

     The hello_xr utility exits 0 on success, and >0 if an error occurs.
