CALL FOR PAPERS
                     Thirteenth Annual ACM Symposium on
                           COMPUTATIONAL GEOMETRY
                               June 4-6, 1997
                                Nice, FRANCE

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            The theoretical track welcomes
 submissions that are                  submissions that are
 application-oriented, including       foundation-oriented including
 representational and algorithmic      analysis of geometric algorithms and
 issues arising from applications and  data structures, theoretical issues
 implementation considerations, case   arising from implementations,
 studies of algorithms in application  geometric optimization, analysis of
 contexts, etc.                        geometric configurations, etc.

 Authors wishing to submit to this     Authors wishing to submit to this
 track should send 15 copies of an     track should send 13 copies of an
 extended abstract or paper or         extended abstract or communication,
 communication, to be received on or   to be received on or before December

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.
