A Hands Generator node is a Generator that tracks hand points. It supports all Generator functions, and adds additional functions.
◆ xnCreateHandsGenerator()
Creates an hands generator.
- Parameters
-
pContext | [in] The context in which to create the hands generator. |
phHandsGenerator | [out] A handle to the created hands generator. |
pQuery | [in] Optional. Can be used to select which hands generator to create. If not specified, this function may create any hands generator that is available. |
pErrors | [in] Optional. If provided, will be filled with information about hands generators that could not be created. |
◆ xnRegisterHandCallbacks()
Register to hands callbacks.
- Parameters
-
hInstance | [in] A handle to the instance |
CreateCB | [in] Callback to be called when a new hand is created |
UpdateCB | [in] Callback to be called when an existing hand has a new position |
DestroyCB | [in] Callback to be called when an existing hand has vanished |
pCookie | [in] User's cookie, to be delivered to the callbacks |
phCallback | [out] The handle to these callbacks, to allow unregistration |
◆ xnSetTrackingSmoothing()
Change smoothing factor.
- Parameters
-
hInstance | [in] A handle to the instance |
fFactor | [in] Smoothing factor, in the range 0..1. 0 Means no smoothing, 1 means infinite smoothing. Inside the range is generator dependent. |
◆ xnStartTracking()
Start tracking at a specific position.
- Parameters
-
hInstance | [in] A handle to the instance |
pPosition | [in] The position at which there is a new hand |
◆ xnStopTracking()
Stop tracking a specific hand.
- Parameters
-
hInstance | [in] A handle to the instance |
user | [in] The hand to stop tracking |
◆ xnStopTrackingAll()
Stop tracking all hands.
- Parameters
-
hInstance | [in] A handle to the instance |
◆ xnUnregisterHandCallbacks()
Unregister from hands callbacks.
- Parameters
-
hInstance | [in] A handle to the instance |
hCallback | [in] The handle received from registration |
