<br>
Iver been looking at this for a couple of hours and I just
cant find the probelm.<br>
What is wrong with this geometry definition?<br>
<br>
The last 2 polygons do not show up correctly, they produce
the desired polygon plus some additional unwanted planes,
that flicker as you rotate the model. The problem must be in
this definition as it also occurs in Paraview.<br>
<br>
Any help, have i got the format wrong or something?<br>
<br>
Thanks<br>
