Now the pqSMAdaptor tries to obtain the array status from the information property is not available in the property itself. Utkarsh Takuya OSHIMA wrote: Hi Utkarsh, I had another look into the issue again, and concluded that it's a bug in ParaView. The tracker ID is #7583. The main problem was indeed in the removal of the this-Internal-Property-ResetToDefault() call. Before the removal the ResetToDefault() call subsequently executed vtkSMArraySelectionDomain::SetDefaultValues() which copies the contents of associated information property to the StringVectorProperty. However with the removal now there's nothing which links the information property and the StringVector property, despite the server-client downlink (client/server stream-information helper-information property-array selection domain-string vector property) worked properly until the update of ArraySelectionDomain which interfaces the two properties. Hence the StringDomain of the newly added array name is found in pqSMAdaptor::getSelectionProperty(vtkSMProperty*, unsigned int) while the corresponding StringVectorProperty is not, which led to the had to make up a value for selection text output. I think the fix intended by the removal of ResetToDefault() must be done elsewhere. For clarification, I attached a pseudo reader plugin to demonstrate the problem. Just build as a usual plugin, load into ParaView, and try reading any stub file with the *.pseudo extension. After clicking Apply, you'll see the had to make up... message every time you move the timestep back and forth.

Hi ParaView developers, As I got no answer so far from the list, I did some digging with a debugger. As a result it's looking more like a bug in ParaView, but I'm not confident yet. So far what I found are threefold: 1. If I revert the following modification to pqSignalAdaptorSelectionTreeWidget.cxx on 2008-07-02 Index: pqSignalAdaptorSelectionTreeWidget.cxx === RCS file: /cvsroot/ParaView3/ParaView3/Qt/Components/pqSignalAdaptorSelectionTre eWidget.cxx,v retrieving revision 1.6 retrieving revision 1.7 diff -r1.6 -r1.7 187,188c187,190 this-Internal-Property-ResetToDefault(); --- // Domain changes should not change the property values. This is overriding // the value loaded from state files etc. // this-Internal-Property-ResetToDefault(); , the had to make up a value message disappeared and reader worked as expected. This coincides with my thought that the problem started at around a month ago. 2. After doing AddArray() to the selection object in the reader, ParaView does seem to recognize the newly added item, since in void vtkSMArraySelectionInformationHelper::UpdateProperty( vtkIdType connectionId, int serverIds, vtkClientServerID objectId, vtkSMProperty* prop) numArrays turned out to have the expected number of arrays, and the results of GetArgument() were precisely expected values. I could confirm the new item is added to prop (the last argument in the function prototype above) through SetElement(). The address prop pointed to was 0x078c5b38 in the tracked case. 3. However, when void pqSignalAdaptorSelectionTreeWidget::domainChanged() was executed later, the address this-Internal-Property pointed to was 0x078cd688, which was different from what prop

Re: [Paraview] Calling a self made writer from a self made filter
Hey Rafael,
First, you'll have to add a property to your filter to call the method
that requests the writing as follows:
SourceProxy name=MyFilter class=vtkMyFilter
...
Property name=Save
command=Save /
...
/SourceProxy
Then you have to create a custom object panel (look at the wiki for
plugin examples) which adds a button and then a callback to do
something as follows:
void pqMyPanel::callback()
{
this-proxy()-InvokeCommand(Save);
}

ParaView resizes the window whenever an object is made visible when no other objects are made visible. When you loaded the new state, the smaller cone was made visible first, which caused the window to resize to its bounds.

Re: [Paraview] Python Programmable Filter
Jacques, Couple of ways to solve your problem: * Solution One: If you don't want to deal with the fact that your data is a vtkMultiblockDataSet, apply the Merge Blocks filter after each of the Extract Block filters and then connect to the Programmable Filter to to the output from the Merge Blocks and then your current script should work just fine. The Merge Blocks will convert the vtkMultiBlockDataSet to a vtkUnstructuredGrid on which your script is applicable. * Solution Two: input0 = self.GetInputDataObject(0,0) input1 = self.GetInputDataObject(0,1) output = self.GetOutputDataObject(0) input0Block0 = input0.GetBlock(0) input1Block0 = input1.GetBlock(0) output.CopyStructure(input0) outputBlock0 = input0Block0.NewInstance() outputBlock0.CopyStructure(input0Block0) output.SetBlock(0, outputBlock0) outputBlock0.GetPointData().AddArray(input0Block0.GetPointData().GetArray(pressure1)) outputBlock0.GetPointData().AddArray(input1Block0.GetPointData().GetArray(pressure2)) The above script will work if you are extracting a single block using the Extract Block filter.

Re: [Paraview] vtkSMProxy saving/restoring
Ah I think I know the problem. vtkSMProxy::Copy() copies all properties
even those on the sub proxies. A representation is a complex beast with
several internal subproxies which are linked up internally. You actually
simply want to save/restore the exposed properties so I'd do something
like follows:
void Copy(vtkSMProxy* src, vtkSMProxy* dest)
{
vtkSMPropertyIterator* iter = dest-NewPropertyIterator();
for (iter-Begin(); !iter-IsAtEnd(); iter-Next())
{
vtkSMProperty* destProp = iter-GetProperty();
vtkSMProperty* srcProp = src-GetProperty(iter-GetKey());
if (destProp srcProp)
{
destProp-Copy(srcProp);
}
}
iter-Delete();
}
Use the above Copy instead of vtkSMProxy::Copy().

All display properties are saved/restored perfectly, but after

after restoring I called:
vtkSMObject::GetProxyManager()-UpdateRegisteredProxiesInOrder();

Re: [Paraview] Why does this programmable source not work outside the paraview GUI
The answer is simple: you are missing the UpdateVTKObjects() call to 'apply' the change to the property. If you going to use ...GetProperty(..).SetElement(...) API then after the property has been set, one must call proxy.UpdateVTKObjects(). so in your example: ... pgsrc.GetProperty(Script).SetElement(0, ... ) pgsrc.UpdateVTKObjects() Alternatively you can simply do: pgsrc.Script = . and then you don't have to worry about calling UpdateVTKObjects().

Is it possible that your csv file has a blank line at the end? Anyways, currently there's currently no direct way of visualizing the data read in by CSV except in the spreadsheet view to simply look at the raw data (or plots in CVS paraview). You'll have to write a python programmable filter or source. Look at http://www.paraview.org/Wiki/Here_are_some_more_examples_of_simple_ParaView_3_python_filters.

Re: [Paraview] Object Panel - Model Communication
To get back values from the server, you can use either information properties or information objects. Information properties are properites with information_only=1 set in the XML (eg. in Servers/ServerManager/Resources/rendering.xml the Camera proxy has CameraPositionInfo as an information property). Such properties need an InformationHelper which knows how to obtain the values from the server. For simple Get*() methods, you can use the SimpleDoubleInformationHelper/ or SimpleIntInformationHelper / etc. based on the type of the property. Complex information helpers can be written as well. Look at TimeStepsInformationHelper (vtkSMTimeStepsInformationHelper.h|cxx) as an example. Information objects are used to get data from server which cannot be simply put in a property for example information about the data object produced by a filter (vtkPVDataInformation). These are vtkPVInformation subclasses. You can create you own vtkPVInformation subclass that knows how to collect information and then serialize/deserialize it for transfer to the client from the server (if needed). To gather such information, one uses vtkProcessModule::GatherInformation(vtkIdType connectionID, vtkTypeUInt32 serverFlags, vtkPVInformation* info, vtkClientServerID id) where id is vtkSMProxy::GetID() returned for the proxy from which you want to collect the information. In your case, information property may be an easier solution -- if I understand your problem correctly. There is a pqServerManagerModel instance accessible as pqApplicationCore::instance()-getServerManagerModel() that can be used to access sources/filters their representations, views etc. Take a look at Qt/Core/pqServerManagerModel.h for the API. That should help you access the visualization pipeline. How to get, for instance, the ids of the nodes which are displayed after the application of a filter to the model ? Not sure I understand what you mean by that. Can you please elaborate?

Re: [Paraview] bug in ParaView 3.4.0 server
Are you by any chance using the binaries distributed on www.paraview.org? If so, are you trying to to run the pvserver with mpiexec/mpirun? The distributed binaries are not built with MPI support so cannot be run with mpi. I am asking this since in your error messages there seem to be some mpiexec error messages.

Re: [Paraview] Object Panel - Model Communication
Rafael, It is possible to get the output of a filter in a custom panel. But it most certainly is not recommended. Fetching data from the output of any filter/source should be done only by views such as the render view/xy line plot view/ spreadsheet view etc. However if you insist on getting the data to the client side create a client-delivery representation. Look at the implementation of Fetch() function in Utilities/VTKPythonWrapping/paraview/servermanager.py for details. However I'd still recommend to rethink -- do you really need the full data or just some meta-data that can be obtained from the vtkPVDataInformation associated with the input?

Information objects are used to get data from server which cannot be simply put in a property for example information about the data object produced by a filter (vtkPVDataInformation). These are vtkPVInformation subclasses. You can create you own vtkPVInformation subclass that knows how to collect information and then serialize/deserialize it for transfer to the client from the server (if needed). To gather such information, one uses vtkProcessModule::GatherInformation(vtkIdType connectionID, vtkTypeUInt32 serverFlags, vtkPVInformation* info, vtkClientServerID id) where id is vtkSMProxy::GetID() returned for the proxy from which you want to collect the information. In your case, information property may be an easier solution -- if I understand your problem correctly. There is a pqServerManagerModel instance accessible as pqApplicationCore::instance()-getServerManagerModel() that can be used to access sources/filters their representations, views etc. Take a look at Qt/Core/pqServerManagerModel.h for the API. That should help you access the visualization pipeline. How to get, for instance, the ids of the nodes which are displayed after the application of a filter to the model ? Not sure I understand what you mean by that. Can you please elaborate?

Re: [Paraview] How to visualize multipart/multiblock models
Currently there is no way to hide-show individual blocks in a multiblock dataset or assign colors to them. However, you can apply the Extract Block filter to extract each individual blocks and then apply colors to them or show/hide them. Utkarsh On Thu, Dec 18, 2008 at 6:15 AM, M.

The primary objective for me is to be able to hide and show different parts of the structure. The model itself is not too large (say 50.000 cells). A bonus for me would be that I can assign a different color (or different properties in general) to each of the parts. I have tried a few things with Paraview: 1. Create a set of individual .VTU files and combine them in a .PVD file. This works very nice for building result sequences of the complete model. 2. Create a set of individual .VTU files and combine them in a .PVM file. This works in the sense that I can import a complete model build up from several pieces, but I cannot assign colors to each of the parts and are unable to hide and show individual parts (tried by using the extract datasets filter). 3. Create a XDMF XML file with 2 GRID elements in a single domain. This again allows me to import the model and show hide individual parts. I can still assign only 1 color to the complete model. Is subdivision into multiple showable/hideable parts, including individual color assignment, possible with either XDMF or VTK XML files? If so, can someone post a minimal example? BTW.

Re: [Paraview] Problem with ParaView 3.4 and additional Filter...
Stefan,
Looks like you only loaded the xml for the filter. Loading of xml is
fine when exposing filters already present in VTK but not available to
ParaView GUI. The MyElevataionFilter.xml refers to a new filter class
vtkMyElevationFilter which needs to be compiled. Hence simply loading
xml is not valid here. Instead you should load the plugin shared
library that would be compiled if you turn on BUILD_EXAMPLES when
configuring paraview using CMake. On compiltation there will be
libSMMyElevation.so (or similar on other platforms) that you can load
through the plugin manager.
Look at http://www.paraview.org/Wiki/Plugin_HowTo for details.

To get back values from the server, you can use either
information
properties or information objects.
Information properties are properites with information_only=1 set
in
the XML (eg. in Servers/ServerManager/Resources/rendering.xml the
Camera proxy has CameraPositionInfo as an information
property).
Such properties need an InformationHelper which knows how to obtain
the values from the server. For simple Get*() methods, you can use the
SimpleDoubleInformationHelper/ or SimpleIntInformationHelper /
etc. based on the type of the property. Complex information helpers
can be written as well. Look at
TimeStepsInformationHelper
(vtkSMTimeStepsInformationHelper.h|cxx) as an example.
Information objects are used to get data from server which cannot be
simply put in a property for example information about the data object
produced by a filter (vtkPVDataInformation). These are
vtkPVInformation subclasses. You can create you own vtkPVInformation
subclass that knows how to collect information and then
serialize/deserialize it for transfer to the client from the server
(if needed). To gather such information, one uses
vtkProcessModule::GatherInformation(vtkIdType connectionID,
vtkTypeUInt32 serverFlags, vtkPVInformation* info, vtkClientServerID
id) where id is vtkSMProxy::GetID() returned for the proxy from
which you want to collect the information.
In your case, information property may be an easier solution -- if I
understand your problem correctly.
There is a pqServerManagerModel instance
accessible as
pqApplicationCore::instance()-getServerManagerModel() that can be
used to access sources/filters their representations, views etc. Take
a look at Qt/Core/pqServerManagerModel.h for the API. That should help
you access the visualization pipeline.
How to get, for instance, the ids of the nodes which are displayed
after the application of a filter to the model ?
Not sure I understand what you mean by that. Can you please elaborate?

Re: [Paraview] eternal Unknown CMake command QT4_WRAP_CPP. error
Jorge,
First of, you cannot build new plugins using an installed ParaView (at
for ParaView 3.4.* and earlier, it should work with CVS ParaView). You
need to download the source and build ParaView from scartch. Then set
the ParaView_DIR to the directory in which you've built ParaView.

In 3.4, you can create a vtm file that points to the individual vtu files. You can then color the blocks separately using the vtkCompositeIndex array (just color by it). You can control the color of each block by editing the color map. Alternatively, you can add a cell-centered, 3 component, unsigned char array (RGB) for each block to the file and then color by that array (make sure to turn off the Map Scalar option). As for turning on/off individual block, I am afraid you have to use the Extract Block filter to achieve that.

Oh no, don't need to add a new representation. You'll create a new autostart plugin (http://www.paraview.org/Wiki/Plugin_HowTo#Autostart_Plugins).

Re: [Paraview] [ParaView3-Developer] Locking (MPI?) problems with ParaView 3.5
John, Here's my understanding of what may be happening: * pvclient has done a gather data information and is waiting to receive that data * pvserver0 has received this gather data request is asking all satellites to gather data * pvserver1 also received that gather data request but before is starts processing it, pv1 needs to pass on the message to it's child i.e process 3 (this is the fancy tree based message communication that we are now using. So now, instead of the root node sending the message to all processes one after the other, it uses a tree structure). * pvserver2 I believe is happily waiting for the next message. It already processed the gather data request, sent the response to the root (although root has not processed that response yet) and now is waiting for the next request. * pvserver3 is the rogue. It's stuck in Cancel, hence it won't receive any messages other send to it. This cancel was not done as a part of this gather data request but was done at the end of some previous request.

Sweet. I've committed the patch to CVS.

Thanks yet again for your help. If the problem comes back in another flavour I'll be sure to let you know. JB John, Here's my understanding of what may be happening: * pvclient has done a gather data information and is waiting to receive that data * pvserver0 has received this gather data request is asking all satellites to gather data * pvserver1 also received that gather data request but before is starts processing it, pv1 needs to pass on the message to it's child i.e process 3 (this is the fancy tree based message communication that we are now using. So now, instead of the root node sending the message to all processes one after the other, it uses a tree structure). * pvserver2 I believe is happily waiting for the next message. It already processed the gather data request, sent the response to the root (although root has not processed that response yet) and now is waiting for the next request. * pvserver3 is the rogue. It's stuck in Cancel, hence it won't receive any messages other send to it. This cancel was not done as a part of this gather data request but was done at the end of some previous request. Thus it's not yet able to receive the gather data request pvserver1 is trying to send, consequently freezing pvserver1. Of course, this is just one possible explanation. I've attached a patch.

Re: [Paraview] Why is PKdTree used for IMAGE Volume Rendering?
Do you have any unstructured data being rendering in the scene? KdTree is used to distribute that unstructured data in accordance with the partitions provided by the structured data.

Re: [Paraview] Why is PKdTree used for IMAGE Volume Rendering?
Kevin, The KdTree is still built (using the partitions from the structured dataset set itself -- hence isn't a very compute intensive task) just in case it's needed to partition any unstructured data, hence you're seeing the PKdTree progress. But I don't think that's where it is hanging. Is the progress bar saying PKtree:100 ? It may actually have frozen in the volume rendering code.

Yes, I was able to reproduce the problem with the wavelet source data.
and I got a new datum as well.
It seems I have to load the large image from a .vti file for the error
to occur.
The error does not occur when I create a large image in parallel with
the wavelet source.
Also give me all the steps to reproduce the
problem (since I am not able to reproduce it with 5 procs using
Wavelet source).
Utkarsh
In paraview connected to the builtin server I created a wavelet source
with extents 0 1958 0 1498 0 77 to match my file.
I then saved that to a vti file.
I then restarted paraview and started a 2 core server that the dialog
runs with
mpirun -np 2 \
/home/kevin/kitware/ParaView3_Build/bin/pvserver \
--use-offscreen-rendering
I loaded the image then selected volume rendering for the
representation.
Then BLAMO swap-death.

Re: [Paraview] Changing the default volume mapper in Paraview?
I know it's kind of hacky, but you can simply edit the XML file and change the mapper used. Look at Servers/ServerManager/Resources/rendering.xml. In the XML for UniformGridVolumeRepresentation change FixedPointVolumeRayCastMapper to something else. Then after the definition for FixedPointVolumeRayCastMapper, add a new definition for the VolumeTextureMapper3D and use that in the UniformGridVolumeRepresentation.

Re: [Paraview] Getting proxy names from proxy manager.
The cout is never shown since GetProxyName() returns 0 for the second

vtkSMProxyIterator to iterate over a group (using
iter-Begin(sources)).

When working from Python, it's easy to get a proxy from 'sources' if you know its name from the pipeline. The name even changes when you edit it in the pipeline. In contrast, 'representations' proxies are named 'DataRepresentation1', 'DataRepresentation2', etc., and to find the proper proxy I always have iterate through the representation proxies and check for a match between the proxy from 'sources' and the representation proxy Input. Since I don't understand much about all the client/server/proxy stuff, I don't know if this is a reasonable request, or if it's difficult for PV to do things internally like change the representation name when the source name is changed.
