特征

GEO++, (Graphics System with Editable Objects, Version 2). Previous (incomplete) specifications of GEO++ have been described in Wisskirchen, 1986b, concentrating on a modification of the PHIGS structure concept, and in Wisskirchen, 1989, introducing the overall concept of GEO++, but less complete and without considering the potential of inheritance.

Smalltalk-80 Graphics Kernel,p. 8. The ideas are mainly derived from an analysis of the underlying object-oriented principles and not so much from the actual functionality of the Smalltalk-80 graphics kernel. An extended description of the Smalltalk-80 graphics kernel is presented in Goldberg & Robson, 1983.

More and more products have been implemented with the aid of object-oriented programming techniques and tools, usually as extensions of traditional languages in hybrid development systems. Some of the better known examples are OSF-Motif, News, Objective-C on the NeXT computer, the C extension C++,

Object-Oriented Interface Architecture, to change any portions of code of the application behind the interface. In this sense the MVC triad can be seen as a new concept for modularization of interactive systems. Both concepts, the application framework and the MVC model, may be combined. They constitute an improvement for the design and implementation of interactive systems.

PHIGS and Part Hierarchies,he work of those who defined PHIGS years ago by stressing these critical points. But developments in the field of interactive programming have since progressed. The object-oriented paradigm is gaining more and more ground and, as we shall see, almost necessarily and naturally calls for the revision of some basic principles of PHIGS.
