Member Data Documentation

XnUInt32(* XnModuleUserPositionCapabilityInterface::GetSupportedUserPositionsCount)(XnModuleNodeHandle hGenerator)

Gets the number of user positions supported by this generator.

Parameters
hGenerator[in] A handle to the instance.
XnStatus(* XnModuleUserPositionCapabilityInterface::GetUserPosition)(XnModuleNodeHandle hGenerator, XnUInt32 nIndex, XnBoundingBox3D *pPosition)

Gets the current user position.

Parameters
hGenerator[in] A handle to the instance.
nIndex[in] The user position to get.
pPosition[out] Current user position.
XnStatus(* XnModuleUserPositionCapabilityInterface::RegisterToUserPositionChange)(XnModuleNodeHandle hGenerator, XnModuleStateChangedHandler handler, void *pCookie, XnCallbackHandle *phCallback)

Registers a callback function to user position changes.

Parameters
hGenerator[in] A handle to the instance.
handler[in] A pointer to a function that will be called when user position changes.
pCookie[in] A user cookie that will be passed to the callback function.
phCallback[out] Optional. Will be filled with a handle to be passed to UnregisterFromUserPositionChange.
XnStatus(* XnModuleUserPositionCapabilityInterface::SetUserPosition)(XnModuleNodeHandle hGenerator, XnUInt32 nIndex, const XnBoundingBox3D *pPosition)

Sets the current user position.

Parameters
hGenerator[in] A handle to the instance.
nIndex[in] The user position to set.
pPosition[in] The user position in the frame.
void(* XnModuleUserPositionCapabilityInterface::UnregisterFromUserPositionChange)(XnModuleNodeHandle hGenerator, XnCallbackHandle hCallback)

Unregisters a callback function which was registered using RegisterToUserPositionChange.

Parameters
hGenerator[in] A handle to the instance.
hCallback[in] The handle to the callback returned from RegisterToUserPositionChange.
