<h1>Test Example for Segment Description</h1>

 <P>If you want that the <A HREF="outtest.html">test output</A> works
correctly, you of course have to define the colors. That means, we
need an instance of the class <B>wzSegmentDescription</B>. This
instance has to be initialized before the call of <A
HREF="cogoutput.hxx"> cogOutput</A>.

 <P>For this purpose we define here a derived class
<B>wzSegmentTest</B> so that the constructor initializes the colors.
Then we declare one instance <B>test</B> as a static variable.

 <P>If this file will be included into the <A HREF="test.html"> main
program</A> before <B>main()</B>, the colors will be initialized.

 <P>You can replace this segment description by other test code with
the following command:

 <P>&gt; use seg <B>opt</B>

 <P>Here, <B>opt</B> denotes one of the following options:

 <UL>
 <LI> without option, this default will be recovered. Moreover, you
see the actual list of options. Mail me if the list below is invalid;
 </UL>

<PRE>
#include "<A HREF="wzsegment.hxx">wzsegment.hxx</A>"

class test_segment_description: public wzSegmentDescription
{
public:
	test_segment_description();
};

test_segment_description::test_segment_description()
:wzSegmentDescription()
{
  int i; wzRegion r; wzFace f; wzEdge e; wzVertex v;
  r = wzRegion("default region");
  f = wzFace("default face");
  e = wzEdge("default edge");
  v = wzVertex("default vertex");
  for(i=2;i<64;i++){
	r = wzRegion("unknown region");
	f = wzFace("unknown face",wzFace(i));
  }
  wzRegion( 1).color()="#099011311";
  wzRegion( 2).color()="#201000";
  wzRegion( 3).color()="#000300611";
  wzRegion( 4).color()="#111111111";
  wzRegion( 5).color()="#b11a00155";
  wzRegion( 6).color()="#311200211";
  wzRegion( 7).color()="#000d11100";
  wzRegion( 8).color()="#100300111";
  wzRegion( 9).color()="#300300300";
  wzRegion(10).color()="#100011211";
  wzRegion(11).color()="#400711911";
  wzFace  ( 1).color()="#099011311";
  wzFace  ( 2).color()="#201000";
  wzFace  ( 3).color()="#000300611";
  wzEdge  ( 1).color()="#099011311";
  wzVertex( 1).color()="#099011311";
}
</PRE>

 <P>Now, before the output one instance of <B>wzSegmentTest</B> has to
be defined. This calls the constructor. Only after this, the colors,
names and materials are appropriately initialized.
