Hi, the operator-> method of a SomeClassPtr returns the associated SomeClass. As most of the FieldContainers in OpenSG are derived from AttachmentContainer, it may look as if an AC were returned.
In your case, the operator-> of CameraPtr returns a Camera object, which is derived from CameraBase, where we find (OSGCameraBase.h): virtual Real32 &getNear(void); virtual const Real32 &getNear(void) const; [ If you're still interested in Attachments, have a look at http://www.opensg.org/doc-1.4.0/PageSystemFieldsNFieldContainers.html (bottom of page) or Tutorials/15attachments.cpp of the source code. ] Björn --- Mathias Lorente <[EMAIL PROTECTED]> schrieb: > Hello, > > Could someone explains me in few words how > AttachmentContainer works ? > > For example, if I have an object firstCam of type > CameraPtr, I can do : > firstCam->getNear() ; and get appropriate result. > But I've just taken a > look to the operator->() and I noticed that it > returns an > AttachmentContainer pointer.
