Re: [Paraview] vtkCompositeDataSet - memory ?
Andy Bauer wrote: ...They should also have the same vtkPointData as a result so that data is not duplicated. In my own experience, it is often the case that different Data arrays can be defined on the 3D blocks and on the 2D boundary surfaces. I just wanted to point out that ParaView is smart enough to enable this and to annotate data arrays of name VAR as VAR (partial). Thus, there is no confusion for the User that he/she is selecting a data array that is strictly defined on only a subset of parts.

[Paraview] use of vtkSynchronizedTemplates
Hi! I want to display isosurfaces of values I compute in my filter, so looking at vtkContourFilter, I got the idea to use the vtkSynchronizedTemplates3D (as my filter is going to handle 3D ImageData). I have a vtkSynchronizedTemplate3D as an instance of my filter, in the constructor it´s initialized and then I do the following: this - SynchronizedTemplates3D - SetInput(TauSet); this - SynchronizedTemplates3D - ComputeNormalsOff(); this - SynchronizedTemplates3D - ComputeGradientsOff(); this - SynchronizedTemplates3D - SetComputeScalars(1); this - SynchronizedTemplates3D - SetNumberOfContours(1); this - SynchronizedTemplates3D - SetValue(0, TauValue); int ext[6]; inInfo - Get(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(), ext); this - SynchronizedTemplates3D - ThreadedExecute(TauSet,inInfo,outInfo,ext, TauValues); It does compile, but running I get an segmentation fault, debugging and backtracing I get: #0 0x7f42ffc5eb10 in ContourImagedouble () from /home/happenhofer/Paraview/build-svn/bin/libvtkGraphics.so.pv3.4 #1 0x7f42ffc5a308 in vtkSynchronizedTemplates3D::ThreadedExecute () from /home/happenhofer/Paraview/build-svn/bin/libvtkGraphics.so.pv3.4 #2 0x7f4309195f06 in vtkTauFilter::RequestData () from /home/happenhofer/Paraview/build-svn/bin/libvtkPVFilters.so vtkTauFilter would be my filter, so the error occurs in ContourImagedouble. Does anyone have an idea even how to find the problem? That would be a great help.. and just in general - calling ThreadedExecute would execute the SynchronizedTemplate filter and return a grid with the isosurface computed, does it not? or do I have to specifiy the output somehow? thx a lot, Natalie Happenhofer _ El doble de diversión: con Windows Live Messenger comparte fotos mientras charlas. http://www.microsoft.com/windows/windowslive/products/messenger.aspx___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview

[Paraview] Open vtk with zlib
Hi,
I try to write a VTK compressed file (uncompressed works fine), but I
have the following error when I open it in Paraview:
ERROR: In /build/buildd/paraview-3.2.2/VTK/IO/vtkXMLDataParser.cxx, line
434
vtkXMLDataParser (0xa02c998): Error reading beginning of compression
header. Read 0 of 12 bytes.
ERROR: In
/build/buildd/paraview-3.2.2/VTK/IO/vtkXMLUnstructuredDataReader.cxx,
line 515
vtkXMLUnstructuredGridReader (0xa030228): Cannot read points array from
Points in piece 0. The data array in the element may be too short.
I don't understand what is wrong. I followed instructions from
(http://www.vtkedge.org/Wiki/VTK_XML_Formats), using only one block at
the moment. I read the header with GHex and it seems OK. The critical
part of the code is (zlib_compress is a function I implemented to
compress the buffer). :
#ifdef HAVE_ZLIB
if (compression_level!=0){
unsigned int header[4];
header[0]=1;
header[1]=data_size;
header[2]=0;
header[3] = ((int)(data_size*1.002))+13;
unsigned char *compressed_sol = (unsigned char*)malloc (header[3]);
zlib_compress((unsigned
char*)buffer_sol.str().c_str(),compressed_sol,data_size,header[3],compression_level);
fstream_sol.write((char *)header,4*sizeof(unsigned int));
fstream_sol.write((char*)compressed_sol,header[3]);
free(compressed_sol);
}else
#endif
{
fstream_sol.write((char *)(data_size),sizeof(unsigned int));
fstream_sol.write(buffer_sol.str().c_str(),pos_end-pos_start);
}
Do you have any idea of what can be wrong?
Thanks for any help,
Sébastien

Re: [Paraview] pm.GetProxiesInGroup() returns tuple keys?
Hey Berk,
Say I have a pipeline with a box and point source, from the Python
shell (CVS Feb 18, 2009):
Python 2.5.2 |EPD 2.5.2001| (r252:60911, Aug 4 2008, 13:45:20)
[GCC 4.0.1 (Apple Computer, Inc. build 5370)] on darwin
from paraview.simple import *
pm = servermanager.ProxyManager()
pm.GetProxiesInGroup(sources)
{('Box1', '363'): paraview.servermanager.Box object at 0x224c5670,
('PointSource1', '114'): paraview.servermanager.PointSource object at
0x224c5530}
I can program around it, but I was just curious what the the second
member of the tuple is for.
