makVrv::DtOculusEventManager Class Reference

Detailed Description

This class is responsible for processing Oculus Touch controller events and translating them into the common VR controller event format. It communicates with the Oculus SDK to retrieve controller state information and dispatches controller events to registered event processors.

Note

This class is created automatically by the DtVirtualRealityDriver and is not intended to be instantiated directly by users.

Constructor & Destructor Documentation

DtOculusEventManager() [1/2]

makVrv::DtOculusEventManager::DtOculusEventManager ( )

private

Unused default constructor.

~DtOculusEventManager()

virtual makVrv::DtOculusEventManager::~DtOculusEventManager ( )

overridevirtual

Virtual destructor.

Cleans up Oculus event manager resources and releases connections to the Oculus SDK.

DtOculusEventManager() [2/2]

makVrv::DtOculusEventManager::DtOculusEventManager ( DtDe & de )

protected

Constructor.

Parameters

de	Reference to the display engine

Initializes the Oculus event manager with a reference to the display engine. This constructor is only called by the registerInstance method and should not be called directly.

References de().

Member Function Documentation

instance()

static DtVirtualRealityEventManager & makVrv::DtOculusEventManager::instance ( DtDe & de )

static

Gets the singleton instance of the Oculus event manager.

Parameters

de	Reference to the display engine

Returns

Reference to the singleton instance

Exceptions

DtCorruptedState

if it is unable to get the instance

Returns the singleton instance of the Oculus event manager, creating it if it doesn't already exist. This method is called by the VR driver during initialization.

References de(), and makVrv::DtVirtualRealityEventManager::DtVirtualRealityEventManager().

processVrEvents()

virtual void makVrv::DtOculusEventManager::processVrEvents ( )

overrideprotectedvirtual

Collects and dispatches events from the Oculus VR system.

Polls the Oculus SDK for controller state updates, processes button and analog input events, and dispatches them to registered event processors.

Note

This method is called by the DtVirtualRealityDriver during the update cycle and is not intended to be called directly by users.

Implements makVrv::DtVirtualRealityEventManager.

updateControllerPositions()

virtual void makVrv::DtOculusEventManager::updateControllerPositions ( ovrTrackingState & tracking )

protectedvirtual

Updates controller positions from Oculus tracking data.

Parameters

tracking

The Oculus tracking state containing position and orientation data

Processes the controller tracking data from the Oculus SDK and updates the internal controller state with new position and orientation information.

updateControllerInputs()

virtual void makVrv::DtOculusEventManager::updateControllerInputs ( ovrInputState & inputState )

protectedvirtual

Updates controller input states from Oculus input data.

Parameters

inputState

The Oculus input state containing button and analog input data

Processes the controller input data from the Oculus SDK and updates the internal controller state with button presses, touches, and analog input values.

findDeviceType()

virtual DtVirtualRealityControllerState::Bitfield makVrv::DtOculusEventManager::findDeviceType ( DtVirtualRealityControllerState::ControllerId deviceId ) const

protectedvirtual

Determines the device type for a given controller ID.

Parameters

deviceId

The controller identifier to query

Returns

Bitfield representing the device type

Maps an Oculus-specific device identifier to the common controller device type enumeration used throughout the application.
