[vtkusers] Visulazing values rather than coordinates

John, this sounds about what I wanted. One another question though. How do the coordinates get incremented in VTK for the Structured Points dataset format? For a simple (3,3) grid how would the ordering look?
0,0,0
0,0,1
0,0,2
0,1,0
0,1,1
0,1,2
...?

Arun,
Your coordinates look structured, which is good. You can make a structured points dataset and render the volume with any of the vtk rendering options (texture mapping, raycasting etc.). Your 2D data would just be an image so have a look at vtkImageViewer. For volumes, have a look at SimpleRayCast.tcl in the Examples/VolumeRendering/ directory of vtk4. One warning, I think all of the rendering methods will not render float values so you may need to cast/scale to the appropriate type. Check the doxygen pages of the rendering method for specifics....john

Subject: [vtkusers] Visulazing values rather than coordinates
Hi all,
I am not sure how exactly to visualize this input data I have at hand. I
have looked through the sample files and have come up with nothing. as most
of them deal with coordinates rather than the value at the coordinates. I
have included a portion of the file. The format is
[x y z]: value_at_that_coordinate
Any help suggestions as to what class to use to visualize this will be most
appreciated. The data is currently in 2D, but there will be 3D data as well.
Thanks,
Arun
