vtkDecimatePro Problem<BR><BR></FONT></DIV>
<P>I'm graduated student from South Korea.<BR>While looking for the data for
vtk, I found this page.<BR>Can I have a question?<BR>I have just started vtk
for my project.<BR>In vtk, there are four kinds of mesh simplication and now
I'm trying to do it.</P>
<P>This is the simple source from book.</P>
<P> </P>

<P><BR>I tried many things, but I couldn't get decimated image.<BR>Just, I
could get Original Image.<BR>What is the problem??<BR>Please answer
me.</P>
<P>Have a Nice day!</P>
