 Geometer

----------------------------------------------------------------------

From: "C. Connolly" <GEOMETER@cs.umass.EDU>
Subject: Geometer


The GE R&D center and (more recently) the vision group at UMass have
been developing and using a solid modeler with some algebraic
manipulation capabilities for various vision & automated reasoning
experiments.  The system is called "Geometer", and some of its salient
features are:

  - Written in Common Lisp (runs on Symbolics, TI, Lucid, DEC)
  - Reliable at planar modeling
  - Capable of curved surface modeling
  - contains machinery for polynomial & transcendental function
    arithmetic, algebraic numbers, Grobner basis computation.
  - contains machinery for various projections & transformations

It is available via anonymous FTP from COINS.CS.UMASS.EDU, although some
people have reported trouble with the connection.  The files are in the
directories:

      VIS$DISK:[GEOMETER]*.LISP
      VIS$DISK:[GEOMETER.DOC]*.TEX

If you do get a copy this way, please send a message to
GEOMETER@COINS.CS.UMASS.EDU, just for verification purposes.  More
information will probably be available at the next DARPA IU workshop.
