Dear computational geometers,

some of you may still remember the drawing program Ipe that I wrote in
1993-1994, and in fact some of you are still using it until today.

Well, finally I've rewritten Ipe from scratch, and a preview of the
new version Ipe 6 is available at

(Thanks to Herve Bronnimann for hosting this page!)

For those of you too young to remember, or who for some other reason
have never heard about Ipe, below is a list of the main features.  To
say it even more concisely: Ipe is a drawing program for computational
geometers, written by a computational geometer.

Best wishes,
  Otfried Cheong


Ipe is a drawing editor for creating figures in PDF or (encapsulated)
Postscript format.  It supports making small figures for inclusion
into LaTeX-documents as well as making multi-page PDF presentations
that can be shown on-line with Acrobat Reader.

Ipe's main features are:

 * Entry of text as LaTeX source code. This makes it easy to enter
   mathematical expressions, and to reuse the LaTeX-macros of the main
   document.  In the display text is displayed as it will appear in
   the figure.

 * Produces pure Postscript/PDF, including the text. Ipe converts the
   LaTeX-source to PDF or Postscript when the file is saved.

 * It is easy to align objects with respect to each other (for
   instance, to place a point on the intersection of two lines, or to
   draw a circle through three given points) using various snapping

 * Users can provide ipelets (Ipe plug-ins) to add functionality to
   Ipe.  This way, Ipe can be extended for each task at hand.

 * The text model is based on Unicode, and has been tested with Korean,
   Chinese, and Japanese.

 * Ipe is available for Unix, Windows, and Mac OS X.

 * Ipe is written in standard C++ using the STL, and released under
   the Gnu Public License.
