IVtkTools_ShapePicker Pick() return number is not 0, but GetPickPosition() always return NULL, is this a bug or something need to be set?

Thanks very much

IVtkTools_ShapePicker does not define GetPickPosition() point, only picked entity.
So yes, it might be considered as bug or implementation limitation.

thanks very much.

e.g. one picking many objects. how to get top one? seems only be determined by pick position
