Hi all,<br><br>I have a bunch of random points in 3D with associated scalar and vector values. I have managed to create a vtk polydata <br>file from the data. Here's a link to a sample file in case any of you would like to have a look.
<br><a href="http://acm.cs.uic.edu/~shriram/259200.vtk">http://acm.cs.uic.edu/~shriram/259200.vtk</a><br><br>I am able to draw glyphs and hedgehogs using this dataset. In order to be able to draw iso-surfaces and streamlines, I
<br>understand that we need a structured grid. Is there something in vtk to convert polydata to a structured grid? I have looked <br>at vtkShepardMethod and vtkInterpolatedVelocityField. Shepard method returns vtkImageData (which I can use to draw
<br>iso surfaces but not streamlines since the vector values are missing) and I can't seem to get vtkInterpolatedVelocityField <br>to work correctly.<br><br>Any help would be greatly appreciated.<br><br>Thanks,<br>Shriram
