You could try vtkImageThreshhold and vtkImageMask or vtkImageMathematics to combine the images in advance. <br>For rendering, simple is vtkImageActor.<br> <br><div><span class="gmail_quote">On 8/15/07, <b class="gmail_sendername">

Hello, vtkusers<br><br>I made a movie with VTK to visualize the temperature changes, as shown in the attached screen shot (map.jpg). The red dots are locations of measurements. What I want to do is display a geographic map (
e.g. US map) over this color map showing the state boundaries. The US map is kind of 'floating' above my temperature map, masking the ocean part but not the color changes (as in usmap.jpg). <br><br>Could someone shed some lights on which VTK class to use? I was looking at vtkTexture but I don't think it is the right one.
<br><br>Thanks!<br><span class="sg">Janny<br>
