int32 DeviceId,
int32 ViewIndex,
FQuat & OutOrientation,
FVector & OutPosition
&41;
Remarks
If the device id represents a head mounted display, fetches the relative position of the given eye relative to the eye. If the device is does not represent a stereoscopic tracked camera, orientation and position should be identity and zero and the return value should be false. true if the pose is valid or not. If the device is not a stereoscopic device, return false.
Parameters
| Name | Description |
|---|---|
| DeviceId | the device to request the eye pose for. |
| ViewIndex | the view the pose should be requested for, if passing in INDEX_NONE, the method should return a zero offset. |
| OutOrientation | The orientation of the eye relative to the device orientation. |
| OutPosition | The position of the eye relative to the tracked device |
