GetPixelCoordinatesInViewPoint

XnStatus(* XnModuleAlternativeViewPointInterface::GetPixelCoordinatesInViewPoint) (XnModuleNodeHandle hGenerator, XnNodeHandle hOther, XnUInt32 x, XnUInt32 y, XnUInt32 *pAltX, XnUInt32 *pAltY)

Gets a single pixel coordinates in an alternative view point. This method uses current frame data.

Parameters

hGenerator	[in] A handle to the instance.
hOther	[in] The view point to translate to.
x	[in] X-coordinate of the pixel to be translated
y	[in] Y-coordinate of the pixel to be translated
pAltX	[out] X-coordinate of the pixel in the alternative view point
pAltY	[out] Y-coordinate of the pixel in the alternative view point

IsViewPointAs

XnBool(* XnModuleAlternativeViewPointInterface::IsViewPointAs) (XnModuleNodeHandle hGenerator, XnNodeHandle hOther)

Checks if current view point is as if coming from the other node view point.

Parameters

hGenerator	[in] A handle to the instance.
hOther	[in] The view point to be checked.

IsViewPointSupported

XnBool(* XnModuleAlternativeViewPointInterface::IsViewPointSupported) (XnModuleNodeHandle hGenerator, XnNodeHandle hOther)

Checks if this generator can change its output to look like as if it was taken from a different location, represented by another generator.

Parameters

hGenerator	[in] A handle to the instance.
hOther	[in] The view point to be checked.

Returns

TRUE if view point is supported, FALSE otherwise.

RegisterToViewPointChange

XnStatus(* XnModuleAlternativeViewPointInterface::RegisterToViewPointChange) (XnModuleNodeHandle hGenerator, XnModuleStateChangedHandler handler, void *pCookie, XnCallbackHandle *phCallback)

Registers a callback function to view point changes.

Parameters

hGenerator	[in] A handle to the instance.
handler	[in] A pointer to a function that will be called when view point 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 UnregisterFromViewPointChange().

ResetViewPoint

XnStatus(* XnModuleAlternativeViewPointInterface::ResetViewPoint) (XnModuleNodeHandle hGenerator)

Sets the view point of this generator to its normal one.

Parameters

hGenerator

[in] A handle to the instance.

SetViewPoint

XnStatus(* XnModuleAlternativeViewPointInterface::SetViewPoint) (XnModuleNodeHandle hGenerator, XnNodeHandle hOther)

Sets the view point of this generator to look like as if placed at another generator location.

Parameters

hGenerator	[in] A handle to the instance.
hOther	[in] The view point to be set.

UnregisterFromViewPointChange

void(* XnModuleAlternativeViewPointInterface::UnregisterFromViewPointChange) (XnModuleNodeHandle hGenerator, XnCallbackHandle hCallback)

Unregisters a callback function which was registered using RegisterToViewPointChange().

Parameters

hGenerator	[in] A handle to the instance.
hCallback	[in] The handle to the callback returned from RegisterToViewPointChange().
