<TITLE>COG 1.0 - test_cogeometry_1</TITLE>

<H1>First Cogeometry-Argument For Test-Cogeometries</H1>

 <P>Some cogeometries (
 <A HREF="cogfunctiontest.html">function</A>
 <A HREF="cogmaptest.html">map</A>
 <A HREF="cogintersectiontest.html">intersection</A>
 <A HREF="coguniontest.html">union</A>
 <A HREF="cogsplittest.html">split</A>
 <A HREF="cogoverlaytest.html">overlay</A>
 <A HREF="cogboxtest.html">box</A>
 <A HREF="cogperiodictest.html">periodic</A>
 ) use other cogeometries as arguments. 

 <P>This file defines the default for the first argument for the test
of such cogeometries. You can use also another test cogeometry xxx (if
xxx does not depend on arguments itself) instead of the cogeometry
defined below simply by the command

 <P>&gt; <B>use cog xxx 1</B>

 <P>Here we use a simple <A HREF="cog1dtest.html">1D
cogeometry</A>. This usually looks nice, because of many different
colors, and suggests very well how the operation works.
