<TITLE>COG 2.0: local refinement</TITLE>

<H1>COG 2.0: local refinement</H1>

 <P>Now, let's consider some local refinement possibilities.

<PRE>
#include "<A HREF="coglib.hxx">cog/coglib.hxx</A>"
int main()
{
  cogenOctree base = new CogenOctree();
  base-&gt;setBorder(0.0,1.0,0.0,1.0);
  base-&gt;addPlanesOfPoint(0.1,0.4);
  base-&gt;addPlanesOfPoint(0.6,0.8);
  cogenRefine gen = new CogenRefine(base-&gt;generator());
  gen-&gt;refinementIsotropicalNearPoint(0.002, 0.01,       0.6,0.8,0.0);
  gen-&gt;setPointModeRectangular();
  gen-&gt;refinementNearPoint(0.002,0.01,0,  0.1,0.01,0,     0.6,0.4,0);
  gen-&gt;setPointModeSpherical();
  gen-&gt;refinementNearPoint(0.002,1,0,  0.001,100,0,     0.1,0.4,0);

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