// Stores available interaction profile meta data

|
|
// OpenXR defines and hardcodes all the supported input devices and their
|
|
// paths as part of the OpenXR spec. When support for new devices is
|
|
// introduced this often starts life as an extension that needs to be enabled
|
|
// until it's adopted into the core. As there is no interface to
|
|
// enumerate the possibly paths, and that any OpenXR runtime would likely
|
|
// limit such enumeration to those input devices supported by that runtime
|
|
// there is no other option than to hardcode this.
|
|
//
|
|
// Note that we need to include paths of our extensions in our action map
|
|
// regardless of whether the developers machine supports the extension or
|
|
// not. Unsupported paths are filtered out when the action map is submitted
|
|
// to the OpenXR runtime.
|
|
//
|
|
// Note on action type that automatic conversions between boolean and float
|
|
// are supported but otherwise action types should match between action and
|
|
// input/output paths.
