Sub-element isosurfaces for VTK unstructured grid


(Ander Biguri) #1

Hi,

I have a VTK unstructured grid with scalar values and I’d like to obtain an isosurface for it. However, when I use the threshold filter, the result is not “sub-element” as in the elements are either in or out, but there is no smooth isosurface. The same result comes from the use of the Isovolume filter. I read that the contour filter may work, but it is apparently disabled for my type of data.

Is there any way I can get a smooth isosurface for this data?

Sounds like you have only cell data available. You can run Cell Data to Point Data to get the point-associated data the Contour filter needs to produce a surface.

Fantastic, thanks for the reply.
