) |
Gets a single pixel coordinates in an alternative view point. This method uses current frame data.
hInstance | [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 |
XN_C_API XnBool XN_C_DECL xnIsViewPointAs | ( | XnNodeHandle | hInstance, |
XnNodeHandle | hOther | ||
) |
Checks if current view point is as if coming from the other node view point.
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be checked. |
XN_C_API XnBool XN_C_DECL xnIsViewPointSupported | ( | XnNodeHandle | hInstance, |
XnNodeHandle | hOther | ||
) |
Checks if this generator can change its output to look like it was taken from a different location, represented by another generator.
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be checked. |

XnStateChangedHandler | handler, | ||
void * | pCookie, | ||
XnCallbackHandle * | phCallback | ||
) |
Registers a callback function to view point changes.
hInstance | [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 xnUnregisterFromViewPointChange(). |
XN_C_API XnStatus XN_C_DECL xnResetViewPoint | ( | XnNodeHandle | hInstance | ) |
Sets the view point of this generator to its normal one.
hInstance | [in] A handle to the instance. |
XN_C_API XnStatus XN_C_DECL xnSetViewPoint | ( | XnNodeHandle | hInstance, |
XnNodeHandle | hOther | ||
) |
Sets the view point of this generator to look like as if placed at another generator location.
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be set. |
XN_C_API void XN_C_DECL xnUnregisterFromViewPointChange | ( | XnNodeHandle | hInstance, |
XnCallbackHandle | hCallback | ||
) |
Unregisters a callback function which was registered using xnRegisterToViewPointChange().
hInstance | [in] A handle to the instance. |
hCallback | [in] The handle to the callback returned from xnRegisterToViewPointChange(). |
