That's correct -- the cell information specifies the points by index. You
can find more information on the VTK file formats here:

Hello everyone!
I have created a vtk File with point coordinates, and cell definitions. As I am
getting distorted surfaces I was wondering what it could be.
The coordinates are nodal coordinates taken from a FE Model. The elements are
defined by the IDs of their corresponding nodes.
So it
you can use xdmf, with a .xmdf file for the light data (meta data), and
2 files or more (hdf5 or binary) for the heavy data (field data, point
data, connectivity...).

Hello!
I use VTK file format for visualizing scientific data in Paraview. I write
in this file mesh (point_data + cell_data) and Field Data (pressure
distribution for each point and etc.). Is it possible to write mesh data
and field data
I am pretty sure that both the Legacy VTK and the XML VTK do not
support writing out the mesh and field data as different files.

Hi Jeff,
the points coordinates are implicit which mean that once you defined
your grid by its size/spacing/origin, your are fine. And the only
thing that is missing is the data that you try to show. Those data can
be located at each point of the grid or at the center of each cell
(cell: small
Assuming that you are defining a uniform rectilinear grid, you need
STRUCTURED_POINTS. As for defining opacity, what is your goal? To do volume
rendering? Other than when using volume rendering, opacity does not have any
effect.
If you need to define an arbitrary set of cubes, you probably need
This is great, thanks Berk and Sebastien. Yes, I am trying to do volume
rendering. My dataset represents a 3D grid occupancy map, where each cell has a
specified likelihood of occupancy. I'd like to render that as a set of unit
cells, where the opacity is directly related to the likelihood of
What you need is to volume render cell data instead of point data.
Unfortunately, ParaView does not support volume rendering of cell data in
images. However, it supports volume rendering of cell data in unstructured
grids. Try this:
- Create a STRUCTURED_POINTS with cell data
- Load it
- Apply
Hey, cool, I just tried that on some test data, and it looks like it might do
the trick. I do have a rather large dataset, but I'll try both this and
Sebastian's suggestion and see what happens. Thanks!

Hi Jeff,
on the help page of vtk (http://www.vtk.org/VTK/help/documentation.html)
you do have a link on the VTK file format.
You should be able to find all the informations that you need here:

Thanks, but I'm totally new to the VTK file format and ParaView, and the
documentation is not clear. It seems like the STRUCTURED_GRID geometry is the
proper one for what I need, but I can find virtually no examples of it's use.
For instance, if I want to specify a set of unit cubes from a set
Hi all,
I'm using ParaView to visualize a dataset, and I'm trying to generate an ASCII
VTK file that will specify a set of voxels, where each voxel has an associated
color and opacity. Does anyone have any suggestions for how I should format the
file? It seems like this should be easy, but I
