The Alternative View Point capability (XN_CAPABILITY_ALTERNATIVE_VIEW_POINT) allows a Generator to transform its data to appear as if the sensor is placed in another location. For example, when more than one sensor is active (or one sensor that produces several outputs coming from close locations, yet not the same one), one sensor can change its data to appear as if coming from the location of the other sensor, so that both data buffers represent the same (for example depth and image maps, where the same coordinates in the map represent the same location is the scene).
Checks if current view point is as if coming from the other node view point.
- Parameters
-
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be checked. |
Checks if this generator can change its output to look like it was taken from a different location, represented by another generator.
- Parameters
-
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be checked. |
- Returns
- TRUE if view point is supported, FALSE otherwise.
Registers a callback function to view point changes.
- Parameters
-
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(). |
Sets the view point of this generator to its normal one.
- Parameters
-
hInstance | [in] A handle to the instance. |
Sets the view point of this generator to look like as if placed at another generator location.
- Parameters
-
hInstance | [in] A handle to the instance. |
hOther | [in] The view point to be set. |
