 <H2>CogeometryEllipsoid</H2>

 <P>Here we create an ellipsoid. The implementation is based on the
usage of the class <A HREF="cogfunctiontest.html">
CogeometryByRegions</A>.

 <P>The implementation of the ellipse in <A
HREF="cogsimple.hxx">cogsimple.hxx</A> and <A
HREF="cogsimple.cxx">cogsimple.cxx</A> may be used as a pattern how to
create other cogeometries which depend on a fixed number of
parameters.


 <P>The class <B>CogeometryEllipsoid</B> defines an ellipsoid (main
axes in coordinate direction) by the center <B>(px,py,pz)</B> and the
radius in each direction <B>(rx,ry,rz)</B>.
