[Paraview] Problems writing an .vtu file

2010-01-28 Thread s . habbinga
Hello everybody,

I've been trying to write a c++ function to convert my data into .vtu
files. Unfortunately, paraview isn't able to read my .vtu files. I get
the following error-message:

ERROR: In
/home/zam/domini/paraview/ParaView3src/VTK/Filtering/vtkExecutive.cxx,
line 757
vtkCompositeDataPipeline (0x8cf34b0): Algorithm
vtkXMLUnstructuredGridReader(0x8d915d0) returned failure for request:
vtkInformation (0x90c34e8)
  Debug: Off
  Modified Time: 383066
  Reference Count: 1
  Registered Events: (none)
  Request: REQUEST_INFORMATION
  FORWARD_DIRECTION: 0
  ALGORITHM_AFTER_FORWARD: 1


I'm obviously doing something wrong... can anyone help? I really can't
find the error. Below, you find a sample .vtu file.
Thanks in advance!!

Sonja

[Paraview] Implementing an Interactive Reader

2009-11-04 Thread s . habbinga
Hi,

I would like to write a reader plugin which allows some kind of
interaction: after reading the whole dataset (which is particle data and
will be mapped to a imagedata), the user should be able to select a
volume of interest. Thereupon, the reader has to reread the dataset and
map it to the imagedata with the new extent. I don't want to use the
create subset filter, because I don't want the VOI to be of a lower
resolution.
Any ideas how I could use a box-widget to specify a volume of interest
and cause the reader to reread the data mapping it to the new imagedata?

Thanks in advance,
Sonja
