      public static final int HANDPOSES
      The struct member offsets.

      public static final int HANDSTATUSFLAGS
      The struct member offsets.

    • CALIBRATEDORIGIN

      public static final int CALIBRATEDORIGIN

  • Constructor Details

    • OVRTrackingState

      public OVRTrackingState(ByteBuffer container)
      Creates a OVRTrackingState instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct<OVRTrackingState>

    • HeadPose

      public OVRPoseStatef HeadPose()
      Predicted head pose (and derivatives) at the requested absolute time. The look-ahead interval is equal to (HeadPose.TimeInSeconds - RawSensorData.TimeInSeconds).

    • StatusFlags

      public int StatusFlags()
      HeadPose tracking status described by ovrStatusBits.

    • HandPoses

      public OVRPoseStatef.Buffer HandPoses()
      The most recent calculated pose for each hand when hand controller tracking is present. HandPoses[ovrHand_Left] refers to the left hand and HandPoses[ovrHand_Right] to the right hand. These values can be combined with ovrInputState for complete hand controller information.

    • HandPoses

      public OVRPoseStatef HandPoses(int index)
      The most recent calculated pose for each hand when hand controller tracking is present. HandPoses[ovrHand_Left] refers to the left hand and HandPoses[ovrHand_Right] to the right hand. These values can be combined with ovrInputState for complete hand controller information.

    • HandStatusFlags

      public IntBuffer HandStatusFlags()
      HandPoses status flags described by ovrStatusBits.

    • HandStatusFlags

      public int HandStatusFlags(int index)
      HandPoses status flags described by ovrStatusBits.

    • CalibratedOrigin

      public OVRPosef CalibratedOrigin()
      the pose of the origin captured during calibration.

      Like all other poses here, this is expressed in the space set by RecenterTrackingOrigin, or SpecifyTrackingOrigin and so will change every time either of those functions are called. This pose can be used to calculate where the calibrated origin lands in the new recentered space. If an application never calls RecenterTrackingOrigin or SpecifyTrackingOrigin, expect this value to be the identity pose and as such will point respective origin based on ovrTrackingOrigin requested when calling GetTrackingState.
