<H1>COG 2.1</H1>

<H2>3D Grid Generation and Geometry Description Package</H2>

 <P><B><A HREF="list.html">COG 2.1</A></B> is a 2D and 3D Delaunay
grid generation package with local anisotropic refinement, based on a
 <A HREF="cog.html">geometry interface</A> which allows almost
arbitrary geometries (solid modelling with boolean operations,
funtional definition, pixmaps).

<H2><A HREF="tutorial.html">Documentation</A></H2>

 <P>The <B><A HREF="tutorial.html">tutorial</A></B> contains working
test code for the following and many other examples:

 <P>The <A HREF="public.html">public domain version</A> can be
 <A HREF="cog.tar.gz">downloaded</A>.  It contains the full 3D
geometry description and many 3D grid generation features of the
 <A HREF="pricing.html">full version</A>.

 <P>At the <A HREF="http://www.wias-berlin.de">WIAS</A> the
 <A HREF="wias.html">full version is installed at
/usr/local/lib/cog</A>.

<H2><A HREF="list.html">Misc</A></H2>

 <P>Some general purpose C++ classes used in COG 2.1 have been
separated into the <A HREF="wztutorial.html"> C++ library WZ 1.1</A>.

 <P><A HREF="new2_1.html">Interface differences with version 2.0</A>:
Coordinate transformation management changed, operations <I>run, use</I>
renamed - use now <B>cog</B> resp. <B>coguse</B>.
