David, thank you so much for the fast response! Your suggestions worked
out beautifully. Best, Alexander
Thank you!

The output type of this reader is a "curvilinear structured grid"
(vtkRectilinearGrid). ParaView will only volume render vtkImageData
(completely structured) and vtkUnstructuredGrid (completely
unstructured). So, convert what you have to an unstructured grid. A
simple way to do that is apply the threshold filter and make the
threshold include the entire range. Then volume rendering will be
available to use.
For streamlines, the help for StreamTracer under Input Restrictions
(http://paraview.org/Wiki/ParaView/Users_Guide/List_of_filters#Stream_Tracer),
says the input must be a vtkDataSet (which all of the above subclass)
so you are fine there. But it also says that the data set must
contains a point centered array with three components. You may need to
apply the cell to point filter to do that, or possibly use the
calculator filter to combine three independent point arrays into a
single vector array.

Hi Seb, thank you for the blazing fast response! This allows me to see
slices through the variables on the grid, so the data is read-in correctly.
However, I am at a loss how to do a 3D volume rendering or a streamline
tracing of data on my structured grid. In order to do that, as I
understand, I need to apply a filter "Table To Structured Grid", as
explained at
http://paraview.org/Wiki/ParaView/Data_formats#Displaying_data_as_structured_grid
. However, this filter is grayed out (screenshot:
http://www.princeton.edu/~atchekho/grayed_out_filter.jpg ).
What should I do in order to do 3D volume rendering or tracing streamlines?
Thank you very much,
Alexander

In the toolbar, you have to select "Surface" instead of "Outline", and
slightly on the left change "Solid Color" by your field name.

Hello All,
I am having trouble reading a binary VTK file in Paraview. Here is a
simple
VTK file (zipped paraview_test.vtk:
http://www.princeton.edu/~atchekho/paraview_test.zip , 29Kb) generated
by
visit_writer plugin for VisIt. The file uses a curvilinear structured
grid.
The file opens and renders OK in VisIt. However, when I open it in
ParaView, the grid shows fine but the properties box stays empty (see
screenshot at http://www.princeton.edu/~atchekho/properties_tab.jpg ,
83Kb),
and I cannot visualize any variables. I know the variables are there
because the Information tab does show the variable ("B") that is in the
file
(see screenshot
at http://www.princeton.edu/~atchekho/information_tab.jpg ,
115 Kb). I tried searching on the web and found that this can happen if
a
reader plugin does not populate the properties
(http://www.paraview.org/pipermail/paraview/2011-April/021081.html). In
this
case reader plugin is a standard VTK reader. Is this a known bug?
Thank you,
Alexander
