Member Descriptions

  • type is the XrStructureType of this structure.

  • time is an XrTime at which the facial expressions are requested.

Description

Applications should request a time equal to the predicted display time for the rendered frame. The runtime will employ appropriate modeling to provide expressions for this time.
