<TITLE>COG 1.0 - test_cogeometry_2</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 second 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 2</B>

 <P>Here we use a simple <A HREF="cogtorustest.html">torus</A>.  Using
a lot of different colors like in the <A HREF="cog1test.html">first
argument</A> would be confusing.

<PRE>
#include "cogsimple.hxx"
cogeometry test_cogeometry()
{
  cogFloat rbig=0.9,rsmall=0.3;
  CogeometryTorus *t = new CogeometryTorus(wzRegion(2),wzRegion(1));
  t-&gt;setCenter(0,0.8,0.7);
  t-&gt;setScale(rbig,rsmall); 
  return t;
}
