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.

Deinitialize()

void ezOpenXR::Deinitialize ( )

overridevirtual

Shuts down the XR system again.

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.

GetCurrentTexture()

ezGALTextureHandle ezOpenXR::GetCurrentTexture ( )

overridevirtual

Called by ezWindowOutputTargetXR::RenderCompanionView Returns the color texture to be used by the companion view if enabled, otherwise an invalid handle.

Implements ezXRInterface.

GetHmdInfo()

const ezHMDInfo & ezOpenXR::GetHmdInfo ( ) const

overridevirtual

Returns general HMD information.

Implements ezXRInterface.

GetXRInput()

ezXRInputDevice & ezOpenXR::GetXRInput ( ) const

overridevirtual

Returns the XR input device.

Implements ezXRInterface.

Initialize()

ezResult ezOpenXR::Initialize ( )

overridevirtual

Initializes the XR system. This can be quite time consuming as it will generally start supporting applications needed to run and start up the HMD if it went to sleep.

Implements ezXRInterface.

IsHmdPresent()

bool ezOpenXR::IsHmdPresent ( ) const

overridevirtual

Returns whether an HMD is available. Can be used to decide whether it makes sense to call Initialize at all.

Implements ezXRInterface.

IsInitialized()

bool ezOpenXR::IsInitialized ( ) const

overridevirtual

Returns whether the XR system is initialized.

Implements ezXRInterface.

OnActorDestroyed()

void ezOpenXR::OnActorDestroyed ( )

overridevirtual

Called when the actor created by 'CreateActor' is destroyed.

Implements ezXRInterface.

SupportsCompanionView()

bool ezOpenXR::SupportsCompanionView ( )

overridevirtual

Returns true if a companion window can be passed into CreateActor.

Implements ezXRInterface.
