Fifth Eurographics Workshop on Programming Paradigms in Graphics

                   CALL FOR CONTRIBUTIONS

Maastricht, The Netherlands, 2/3 September 1995

===================================================================

Theme
-----

What is a sufficiently powerful programming paradigm for computer
graphics? Has object-orientation failed as a methodology for
graphics?


Aims and Scope
--------------

In past Eurographics workshops on Object-Oriented Graphics
prominent trends have been a discovery of the limits of
object-orientation in graphics and the exploration of programming
paradigms other than object-oriented programming. The limitations
of object-orientation were felt to lie in such areas as the
expression of relationships between objects. This is an area of
particular strength for the declarative languages, such as
constraint-based languages. On the other hand, the notion of
`state' is absent in declarative languages and is often seen as an
essential aspect of graphical modelling, particularly in simulation
and animation.  As a result of the closing discussion of the last
workshop we plan to broaden the scope of the next workshop, and
call it a workshop on Programming Paradigms in Graphics.

The general aim of the workshop will be to investigate 
applicability, merits and problems of various programming paradigms
in computer graphics, such as:

 - object-oriented
 - functional
 - constraint
 - parallel
 - logic
 - data-flow
 - genetic

The discussion should take place in terms of techniques for design,
modelling and implementation.

Possible topics are: graphics system architectures, overcoming
limitations of paradigms, combining paradigms, application-specific
designs, generic graphics frameworks, distributed graphics,
modeling relations and dependencies, paradigm specific techniques,
comparative studies.  Case studies and comparative evaluations of
successful commercial object-oriented packages for computer
graphics will also be of interest.

Computer graphics is taken in a broad sense, including (but not 
limited to) human interfaces, animation, visualization, multimedia,
geometric modeling, and virtual reality.


Contributions
-------------

Please submit original research papers (10-20 single sided pages,
200 word abstract) for review by the programme committee by the
15th of April 1995. The preferred submission form is by e-mail in
Postscript or LaTeX format. Otherwise send 4 hard copies. Accepted
papers will be reproduced in the workshop proceedings. Shorter
position papers (2-4 pages) may be accepted according to their
relevance to the workshop.

It is the intention of the organizers to publish a selection of 
presented papers. This will either be as a collection of papers 
in a book, as has happened in the past, or in a special issue of 
some appropriate journal. A selection of position papers will be 
published in SIGCHI bulletin.

Schedule
--------

15 April 1995:       Deadline for full paper.
1 July 1995:         Notification of acceptance of full papers.
                     Deadline for position paper for in proceedings.
1 August 1995:       Latest date for position paper for participation.
2, 3 September 1995: Workshop.


Organization
------------

The workshop is organized by CWI (Centre for Mathematics and
Computer Science) and promoted by Eurographics. It is chaired by
Edwin Blake (University of Cape Town and CWI) and Remco Veltkamp
(CWI).
