<TITLE>COG 2.0: standard cogeometries</TITLE>

<H1>standard cogeometries</H1>

 <P>You can extract a cogeometry from every <B>cogenerator</B>.  This
allows to construct the usual standard cogeometries.  For example,
let's use a cogeometry similar to a
 <A HREF="mainoctreetest.html">simple test example</A>:

<PRE>
#include "<A HREF="coglib.hxx">cog/coglib.hxx</A>"
cogeometry test_cogeometry()
{
  cogenOctree gen = new CogenOctree();
  wzIndex i1 = gen-&gt;addBox(wzRegion(2),-1.0,1.0,-1.0,1.0);
  wzIndex i2 = gen-&gt;addBox(wzRegion(3),-0.1,0.8, 0.3,1.0);
  wzIndex i3 = gen-&gt;addBox(wzRegion(4), 0.3,1.0,-0.6,1.0);
  gen-&gt;setFaceOfBox(wzFace(2),i1);
  gen-&gt;setFaceOfBox(wzFace(3),i2);
  gen-&gt;setFaceOfBox(wzFace(4),i3);
  gen-&gt;setFaceOfBoxSide(wzFace(5),i1,wzXdown);
</PRE>

 <P>Now, we extract this cogeometry in the following way:

<PRE>
  gen-&gt;endInitialization();
  return gen-&gt;geometry();
}
</PRE>
