Member Typedef Documentation

typedef struct xn::HandsGenerator::HandCookie xn::HandsGenerator::HandCookie [private]

typedef void(XN_CALLBACK_TYPE* xn::HandsGenerator::HandCreate)(HandsGenerator &generator, XnUserID user, const XnPoint3D *pPosition, XnFloat fTime, void *pCookie)

Callback for the creation of a new hand.

Parameters:

generator	[in] the generator that raised this event.
user	[in] The id of the new hand.
pPosition	[in] The position in which the hand was created.
fTime	[in] Timestamp, in seconds.
pCookie	[in] A user-provided cookie that was given when registering to this event.

Definition at line 3058 of file XnCppWrapper.h.

typedef void(XN_CALLBACK_TYPE* xn::HandsGenerator::HandDestroy)(HandsGenerator &generator, XnUserID user, XnFloat fTime, void *pCookie)

Callback for the disappearance of a hand.

Parameters:

generator	[in] the generator that raised this event.
user	[in] The id of the hand that disappeared.
fTime	[in] Timestamp, in seconds.
pCookie	[in] A user-provided cookie that was given when registering to this event.

Definition at line 3077 of file XnCppWrapper.h.

typedef void(XN_CALLBACK_TYPE* xn::HandsGenerator::HandUpdate)(HandsGenerator &generator, XnUserID user, const XnPoint3D *pPosition, XnFloat fTime, void *pCookie)

Callback for a new position of an already-existing hand.

Parameters:

generator	[in] the generator that raised this event.
user	[in] The id of the hand that moved.
pPosition	[in] The new position of the relevant hand.
fTime	[in] Timestamp, in seconds.
