A little bit update... I just tried out vtkTriangleFilter. It almost worked except warning messages:<br><br><span style="font-weight: bold;">Warning: In \VTK-503\vtk-5.0.3\Filtering\vtkPolygon.cxx, line 613<br>vtkPolygon (01929088): Degenerate polygon encountered during triangulation
<br><br></span>I used vtkCleanPolyData before the filter, but I still got the message. I'm not sure how to deal with the bad triangles yet... The map I got is attached. It looks better except the holes within the polygons.
<br><br>Could someone share some experience?<br><br>Thanks!<br>Janny<br><br><br><div><span class="gmail_quote">On 9/30/07, <b class="gmail_sendername">Janny Dong</b> <<a href="mailto:janny.dong@gmail.com">janny.dong@gmail.com

and I put them in to a vtk file. There are three polygons. I set
scalars and a lookup table in the data file to color them with one
color-blue, for example. My test results are in the attached pictures.
If I draw lines, the map looks perfect. However, if they are displayed
as polygons, I want polygons. Then the map doesn't look right, neither
does the color. Why do I get black areas? How can I draw the polygons
properly? <br><br>Any thought will be appreciated.<br><br>Best,<br><span class="sg"><span>Janny</span>
