Hi, I am writing a custom reader for paraview to read my own data file which
paraview hasn't have.
I have known that the most important method is RequestInformation and
RequestData, and I just want to write a reader that can output the data type
of StructuredPoints with Scalar and some vectors.I ha
Dear PV experts:
I loaded a transient dataset into paraview (3.4.0). This is 3D unstrucutred
mesh.
Is there any tutorial that shows how to "select a point using a mouse"? Then,
plot that point over time?
I know how to select a whole bunch of cells ("select cell through selection"),
but, n
All of the select mechanisms work the same with the plot over time filter.
Simply do a "select points on" selection (the toolbar icon has a triangle with
red points surrounded by a dotted box and a mouse cursor on it) and apply it to
the plot filter in the same way you used the other selection.
Select points find vertices, select cells find cells, I believe you
are trying to find data at a specific location within a cell, which is
not necessarily on a vertex.
Try the probe location filter. Activate it, then press p with the
mouse on the point you are interested in, then click accept. Thi
How can I construct a "simple" contour plot scaled nicely (like the
bar and line plots in Paraview) similar to
http://qwt.sourceforge.net/spectrogramscreenshots.html ?
I have simple rectilinear data - 3 columns 24x365 (x,y) and a third
column of data to provide the contours.
I have imported data
Hi Mark,
This is now fixed on CVS head. Note that the time step slider is gone.
You have to use the global time settings. Loading an MFIX file and
hitting play should work.

Hi,
I have a VTK application where I would like to color differently both sides
of a triangular cell, in order to check whether all of them are correctly
oriented, and to ensure there is no tangling. Do you know how can I achieve
this easily?
Thanks you very much,
Hector.
Hi,
How can i obtain or access the interactor which moves the camera or the
object in the paraview render window? I want to be able to access it so i
can use vrpn and move the object. I have tried earlier retrieving the render
window and creating a vtkrenderWindowInteractor (plus adding a trackbal
Hi, Ken,
Thanks for the reply. Now I can select the point. But, I then select "plot
selection over time" filter, I did not get any plot. The spread sheet view
showed that there is no point in the "plot selection over time" row. I am not
sure why that is. Also, PV did not ask why field vari
Hi, Ken,
Now I am able to plot selection over time, but, only if I select "cell", not
point.
Thanks!

Subject: Re: [Paraview] plot point over time -
Is the data associated with the points or the cells? It may be the
case that your data is cell centered, so when you plot a point over
time there is nothing to plot.
Look at the arrays on the information tab of the object inspector. A
cube icon means the array is associated with the cells, a circl
Dear PV experts:
Sorry to bother you guys about this.
I have a list of vtk files, something like:
a_0.vtk
a_60.vtk
a_360.vtk
a_660.vtk
a_960.vtk
The numbers about is in seconds from OpenFOAM simulation. I load the files
into paraview-3.4.0. I am able to to animation and plot transient data.
Maybe I'm being dense, but if you already retrieved the render window, why not
just call GetInteractor()?

What you are using is not quite right. First, it sounds like you really want
to create a vtkImageData. This data holds a 1D, 2D, or 3D grid of points with
origin and uniform spacing on each axis. Thus, you would inherit from
vtkImageAlgorithm and cast your output to vtkImageData.
Second, the
Unfortunately, that feature is not implemented in ParaView yet. It is
something that I am planning to add before ParaView 3.6. Attached is a plugin
that defines a new view that allows you to color front and back faces
differently. I'm not sure if it compiles against Paraview 3.4 but it

Hi Guys,
I am new to paraview.
I want to open a .hdr image file in paraview.
It seems that paraview doesn't support this format since when i opened it,
there is a dialog asking me to select the responsive of the file.
I can't find the hdr format in the dialog.
How to properly open the .hdr image
Hi all,
I have written a custom paraview reader which populates a 3D
vtkImageData and one of my users tried it with a 3D problem where the
second dimension was of size = 1. When I tried this with standalone
ParaView_3.4.0 it seemed to work correctly by making a 2D image in
the lower win
First of all, what is a .hdr format? Is it related to HDF5? If so, HDF5 is
not natively supported by ParaView. But you can write a small piece of Xdmf
file describing and pointing to the data in your (supposed) HDF5 file.
Renato.

I am not sure if HDR here refers to High Dynamic Range. There is such an
emerging high-fidelity image file format (*.HDR) used to store / encode
original image data (e.g., in 'double' format to record ray tracing or
radiosity results without quantization) whose range (max / min, usually over
10^7 o
