Subject: Objekt-orientierter Graphikstandard

Als Hintergrundinfo von der Siggraph in Las Vegas folgende Infos
(s. auch die beiliegende mail von Edwin Blake) 
Andy van Dam hat eine Gruppe (mit wichtiger industrieller Beteiligung) 
gegruendet, die neuen objekt-orientierten Graphikstandard erarbeiten will. Erste 
Version soll bereits bis zur naechsten Siggraph in einem Jahr ausgearbeitet
werden.
Auf der diesjaehrigen Siggraph wurde (ohne dies im Vortrag explizit zu erwaehnen) 
ein framework fuer den neuen Standard praesentiert. (Eine beschraenkte Zahl von 
Kopien des Vortrags "An object-oriented
framework for the integration of interactive animation techniques" by
Zeleznik, Conner et al. (10 authors), in the SIGGRAPH'91 proceedings
(Computer Graphics Vol. 25, no. 4, pp. 105-112)  koennen von mir angefordert
werden) (wisskirchen@f3.gmd.dbp.de oder wissk@gmdzi.gmd.de).
Andy van Dam ist stark an Zusammenarbeit mit europaeischen Gruppen interessiert.
Das framework beruecksichtigt stark high performance graphics, animation,
constructive solid geometry, dynamics, constraints, etc....
Die Gruppen, die in Deutschland an neuem Standard arbeiten, sind an Mitwirkung
von Graphik-Fachleuten interessiert. (Naehere Infos ueber Stand in Deutschland,
geplante Aktionen etc. koennen von Klaus Kansy (kansy@f3.gmd.dbp.de) angefordert
werden.
 
**** Edwin Blake's comments ***
From Edwin:
Well SIGGRAPH and Las Vegas are behind us and I thought it might be
interesting to for those people who could not go (and those who could
not go to everything) to have a discussion of advances on the
oo-graphics front at SIGGRAPH.

It seemed to me that object-oriented graphics has arrived and if it was
not apparent earlier it is now clearly the mainstream approach to
computer graphics.  Evidence?  Well, Fred Brooks came to our tutorial on
the subject ...  There was also a panel discussion on the topic at which
nothing controversial was said: consensus ?!

More significantly, Andries (Dutch version of the name) van Dam, who got
the Coons award this year, was pushing object-oriented design for his
baby: a new graphics standard to be developed outside the national and
international standards bodies.  You can get a flavour of the approach
they are advocating by looking at the paper "An object-oriented
framework for the integration of interactive animation techniques" by
Zeleznik, Conner et al. (10 authors), in the SIGGRAPH'91 proceedings
(Computer Graphics Vol. 25, no. 4, pp. 105-112).

A manuscript of Steve Cunningham's book (a collection of papers on
object oriented graphics by various authors) was on view at the Wiley
stand: it should be out early next year.  That makes it the third book
on the topic.

Other impressions of SIGGRAPH?  Is it time to move on to new pastures
and leave object-oriented graphics to the developers?
