Member Function Documentation

◆ CreateActor()

ezUniquePtr< ezActor > ezOpenXR::CreateActor ( ezView *  pView,
ezGALMSAASampleCount::Enum  msaaCount = ezGALMSAASampleCount::None,
ezUniquePtr< ezWindowBase >  pCompanionWindow = nullptr,
ezUniquePtr< ezWindowOutputTargetGAL >  pCompanionWindowOutput = nullptr 
)
overridevirtual

Creates a XR actor by trying to startup an XR session.

If SupportsCompanionView is true (VR only), a normal window and window output can be passed in. The window will be used to blit the VR output into the window.

Implements ezXRInterface.

◆ EndFrame()

void ezOpenXR::EndFrame ( )

NOTE: (Only Applies When Tracy is Enabled.)Tracy Seems to declare Timers in the same scope, so dual profile macros can throw: '__tracy_scoped_zone' : redefinition; multitple initalization, so we must scope the two events.
