Sorry to repost. Does anybody have a feel for whether I can apply a filter and essentially produce a 3d volume mesh with associated scalars and transformed vectors, from it's 2d counter part using vtk?
i.e. a cylindrically symmetric simulation converted to a valid 3d volume mesh. I can apply the filter, similar to this thread: http://www.paraview.org/pipermail/paraview/2012-March/024320.html but in my case, rather than for presentational purposes, I need the internal of the rotated shell to be a populated volume mesh. Using the method in the above post, or described in my previous post gives only the outer shell. Any help either way really appreciated!
