CALL FOR PAPERS}
Thirteenth Annual ACM Symposium on COMPUTATIONAL GEOMETRY
June 4--6, 1997
Nice, FRANCE
http://www.inria.fr/prisme/scg97
 
Papers and short communications are invited for submission.
These may address either fundamental problems in geometric computing, or
focus on applications including, but not limited to

	 robotics and virtual worlds,
	 computer graphics,
	 simulation and visualization,
	 image processing,
	 geometric and solid modeling,
	 computer aided geometric design,
	 manufacturing, and 
	 geographical information systems.

The conference has two tracks; an applied track, and a theoretical track.
The applied track welcomes submissions that are application-oriented,
including 

 representational and algorithmic issues arising from applications
   and implementation considerations,                             
 case studies of algorithms in application contexts,              
 etc.

Authors wishing to submit to this track should send 15 copies of an extended
abstract or paper or communication, to be received on or before December 17, 1996 to: 
	Christoph M. Hoffmann
	Computer Science
	Purdue University
	West Lafayette, IN 47907-1398
	USA
	cmh@cs.purdue.edu
	Tel: +1--317--494--6185

The theoretical track welcomes submissions that are foundation-oriented
including

 analysis of geometric algorithms and data structures,
 theoretical issues arising from implementations,
 geometric optimization,
 analysis of geometric configurations, etc.

Authors wishing to submit to this track should send 13 copies of an extended
abstract or communication, to be received on or before December 17, 1996 to:
	Raimund Seidel
	Univ. des Saarlandes
	FB 14, Informatik, Geb. 45, Raum 410
	D-66123 Saarbrucken
	GERMANY
	seidel@cs.uni-sb.de
	Tel: +49--681--302--4448


In doubtful cases submissions to one track may be forwarded
to the other for consideration, unless the authors have explicitly
stated interest in one track only.

Submissions received past the deadline risk rejection
without further consideration. Authors will be notified of acceptance
or rejection by February~19, 1997. A full version of each accepted
contribution in final form will be due by March 19, 1997, for
inclusion in the proceedings.  There will be joint proceedings,
which  will be distributed at the
Symposium and will be subsequently available for purchase from ACM. A
selection of accepted papers will be invited to special issues of
journals.

Papers must present original research. An extended abstract
should begin with a succinct statement of the problems/goals of the
paper, the main results, and the significance of the work in the
context of previous research. It should provide sufficient detail to
allow the program committee to evaluate the validity, quality, and
relevance of the contribution. The entire extended
abstract should not exceed 10 double-spaced pages. An optional
appendix may be included, but this will be used at the program
committee's discretion.


Communications are limited to three pages and will be published in
a separate section of the proceedings. 
They are meant for
reports on experimental results, on experiences with applications of
computational geometry in real-world situations and other practical
issues that are relevant to computational geometry, as well as for
short notes of an algorithmic or combinatorial nature. 
They
will be presented as posters (possibly with implementation demos) at
the conference.

For video submissions please consult the separate call for videos. 

Preceding the symposium there will be
a two-day workshop on geometric computing.  Check the symposium's

CALL FOR VIDEOS
6th Annual Video Review of Computational Geometry
To be presented at the Thirteenth Annual Symposium on Computational Geometry
June 4--6, 1997
Nice, FRANCE
http://www.inria.fr/prisme/scg97
 
Videos are sought for a video review of computational geometry.
 
BACKGROUND: This video review  showcases the use of computer
graphics in computational geometry for exposition and education, as an
interface and a debugging tool in software development, and for the
visual exploration of geometry in research.  Algorithm animations,
visual explanations of structural theorems, descriptions of
applications of computational geometry, and demonstrations of software
systems are all appropriate.  Videos that accompany papers or
communications submitted to the technical program committee are
encouraged.
 
SUBMISSIONS: Authors should send one preview copy of a videotape
to the address below by February 15, 1997.  The videotape should
be at most eight minutes long (three to five minutes, preferred), and
be in VHS NTSC (preferred) or VHS PAL format.

Each videotape must be accompanied by five (5) copies of a one- or
two-page description of the material shown in the video and the
techniques used in the implementation.  Please format descriptions
following the guidelines for ACM proceedings.  
 

Additional materials describing the content of the videos, such as
the full text of accompanying papers, may be included.  
 
Videotapes and accompanying text should be sent to:

NOTIFICATION:
Authors will be notified of acceptance or rejection, and given
reviewer's comments by February 28, 1997.  For each accepted video,
the final version of the textual description will be due by March 16,
1997 for inclusion in the proceedings.  Final versions of accepted
videos will be due May 1, 1997 in the best format available.  The
accepted videos will be edited onto one tape, which will be shown at
the conference, distributed to the participants, and available from
ACM after the conference.
