[vtkusers] Visualizing 2D data in 3D

[Banks, Robert]

Sorry, I wasn't quite right when I said that was what I was after. The data set I have is a 2d array, not 2d line
Info.

So basically a 2d matrix of data points , x columns by y rows.

Sorry for the confusion

Exactly

Thanks

Someone please chime in if there is already a filter to do this in VTK.

What you could do is this:

1) Define your curve
2) make a copy of it rotated it N degrees around the axis of revolution. 360 should be divisible by N. The smaller N is, the smoother your surface will be.
3) make a quad on every 2 points and their corresponding copied points.
4) run vtkCleanPolyDataFilter and vtkTriangleFilter

If no one lets your know about an easier method, this should work. Let us know if you try and get stuck. Also, when you get it to work, please send the code and I'll put it on the wiki.

Thanks,

David
