OpenVR SDK 1.0.9
Drivers:
- Added TrackedDeviceDisplayTransformUpdated, which allows HMD drivers to explicitly specify the 4x3 eye-to-head transforms. The classic mechanism of setting Prop_UserIpdMeters_Float is still supported.
- Added Prop_DriverProvidedChaperonePath_String, which a driver can set on the HMD device to specify a fallback chaperone setup that will be used if no other chaperone data is available for the universe returned by that driver. This string is a JSON object in the same format as the .vrchap file.
- Added VREvent_WirelessDisconnect and VREvent_WirelessReconnect events for display redirect drivers to notify the runtime of display connection status.
