[Paraview] [EXT] Trusses to Tubes

[Dennis Conklin]

David,

Thanks for the insight!

Just fyi, Paraview seems a little unstable if I have too many of these tubed at a time - My blocks are about 200,000 trusses each and it's only safe to process one at a time.

I know there were some surface issues with v4.4 so I need to try it on an earlier version, but no time right now!

Dennis

Hi Dennis,

> ... running extract surface and then tube is working very well for me.  I guess I never thought about a "line" element having a surface but apparently that's a line!

Yes, the "Extract Surface" filter's name is a little misleading. What it really does is convert a dataset from an unstructured grid (which may contain volumetric elements) to a polydata (which may only contain 0-, 1-, or 2-d primitives). In the process, any volume elements are represented by the portions of their bounding surface not shared with other volume elements.

The Tube filter only runs on polydata. So it is not exactly extracting the surface of a line so much as converting representations.
