[Paraview] problems with repeatable input to filter
Hi!
I´m trying to write a filter with multiple inputs, in my case I need two
datasets as input to this filter. In order to achieve that, I have the
following routine in my code:
int vtkTauFilter::FillInputInformation(int port, vtkInformation* info)
{
info - Set(vtkAlgorithm::INPUT_REQUIRED_DATA_TYPE(),vtkDataSet);
info - Set(vtkAlgorithm::INPUT_IS_REPEATABLE(), 1);
return 1;
}
and I put in the /Servers/ServerManager/Resources/filters.xml file the
following:
SourceProxy name=TauFilter class=vtkTauFilter label=TauFilter
InputProperty name=Input command=AddInputConnection
clean_command=RemoveAllInputs multiple_input=1
ProxyGroupDomain name=groups
Group name=sources/
Group name=filters/
/ProxyGroupDomain
...
/SourceProxy
Compiling Paraview works fine, but I get the error:
ERROR: In /ParaView-3.4.0/VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 732
vtkCompositeDataPipeline (0x357dd50): Input port 0 of algorithm
vtkTauFilter(0x357bff0) has 2 connections but is not repeatable.
Does anyone know what´s could be the problem here?
thx a lot,
Natalie

Re: [Paraview] problems with repeatable input to filter
void vtkBlahFilter::SetDataSet1Connection(vtkAlgorithmOutput* algOutput)
{
this-SetInputConnection(0, algOutput);
}
void vtkBlahFilter::SetDataSet2Connection(vtkAlgorithmOutput* algOutput)
{
this-SetInputConnection(0, algOutput);
}
Burlen's code looks right, but I believe the SetDataSet2Connection
should be like this (change 0 to 1):
void vtkBlahFilter::SetDataSet2Connection(vtkAlgorithmOutput* algOutput)
{
this-SetInputConnection(1, algOutput);
}

[Paraview] vtkCompositeDataSet - memory ?
Hi all, I'm writing a reader for a dataset which has boundary faces (tri and quads) as well as volume cells (tets etc..). In would like to use a CompositeDataSet as a container, so that I can easily extract boundary faces which are groupesd in named zones (for ex: upper_surf lower_surf etc...). The problem I encounter is that if I us a vtkMultiblockDataSet composed of vtkUnstructuredGrid there is no relationship between the separate blocks. This means that I need to duplicate points which are shared between the different blocks, duplicate the data associated to thes points etc ... Is there a vtkCompositeDataSet where all the points and data are shared between the branches and the only difference is the cells ? Thank you for your guidance.

Re: [Paraview] vtkCompositeDataSet - memory ?
You can share the points by simply creating one vtkPoints object and then
passing those points to all the unstructured grids in your data object. Then
all the blocks will be sharing that data.
Note, however, that ParaView will not actually check that. Thus it will
probably incorrectly count the number of points and the amount of memory the
points take up multiple times, one for each block. Also, if you pass the data
through a filter that changes the points, those downstream filters will
replicate their point data.

Re: [Paraview] vtkCompositeDataSet - memory ?
If all of the grids that are used in the vtkMultiBlockDataSet derive from vtkPointSet, you can use the same vtkPoints for each of the grids. They should also have the same vtkPointData as a result so that data is not duplicated.

Re: [Paraview] Changing the default volume mapper in Paraview?
In that case simply remove the command attribute from the LockSampleDistanceToInputSpacing property. That way ParaView will not try to call that method on the vtkOpenGLVolumeTextureMapper3D class.

[Paraview] Mesh Subdivision
I have a polydata (vtp) with a bunch of triangles. I want to smooth the mesh. I tried the subdivide filter, but it produces absolutely ridiculous triangles. So I thought this meant the connectivity information was wrong? So I tried the TriangleStrips filter and then the subdivide filter, but now the subdivide filter complains that there are no triangles. I tried triangulate and then subdivide and I get the same mess as in the first case. In all cases, the LoopSubdivision filter simply crashes. There is clearly still something wrong with my understanding of these file formats and which filters can be used on which types of files. Can anyone clarify this for me?
