Hi all,<br><br>I'd like to create a 2D color map of 100 points(10*10). The points are like (x,y,z), where x,y are the data positions, z is the scalar value I want to map color with. I know if I have all the scalar values of the points available, I can put them into vtkPolyData, then use vtkDelaunay2D to do the triangulation, and then use vtkLookupTable and vtkPolyDataMapper to display the map.
<br><br>My problem is, I don't know all the scalar values (z). I only know z values of 16 points for example. How can I do interpolation to get scalar values of all the other points? I tried to use vtkProbeFilter to probe the 16 points with another vtkPolyData of 100 points (scalars unknown), but I got a blank scene in the rendering window.
<br><br>The problem has been bugging me for a while. Any help will be greatly appreciated.<br><br>Janny<br><br><br><h1><br></h1>
