       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.
