<H1>COG 2.1: 3D example of CogenOctree</H1>

 <P>The possibilities of the class
 <A HREF="cogenoctree.html">CogenOctree</A> are available in 3D too.
compared with our <A HREF="mainoctreetest.html">2D test example</A> we
simply have to add some more parameters for the related values in
z-direction:

<PRE>
#include "<A HREF="coglib.hxx">cog/coglib.hxx</A>"
int main()
{
  cogenOctree gen = new CogenOctree();
  gen-&gt;addBox(wzRegion(2), 0.0,0.4, 0.0,0.5, 0.0,0.6);
  gen-&gt;addBox(wzRegion(3), 0.2,1.0, 0.3,1.0, 0.4,1.0);
  gen-&gt;addPlaneZ(0.9);
  gen-&gt;setRegularRefinementZ(1);
</PRE>

 <P>Note that we have defined one plane in z-direction to fix the
z-coordinate of the points of the 2D grid.

<PRE>
  wzgrid grid = (*gen)();
  grid->write("test.sg");
}
</PRE>
