Re: [Paraview] Numpy import error

If there any other problems with this reader then feel free to consult me. 1) typically I make a separate build directory for VTK or ParaView. The test I ran looked for ../../../../vtkData or something like that, so it seems like the test executable has to be four directories deep. So I guess there is a common parent to the data folders and paraview, not sure what this parent would be or if there is a reference for this hierarchy. 2) I guess in this case I would have to experiment when I do make the switch to the newer VTK On Thu, Dec 20, 2012 at 9:45 AM, Andy Bauer andy.ba...@kitware.comwrote: Hi Sohail, Changing the number of fields from 23 to 16 fixed the warnings. I'll get these changes into VTK and then change ParaView so that it can read in WindBlade files with a single process. That may take a week or so though. As for the other questions: 1) If the data directories are called VTKData, VTKLargeData, and ParaViewData and they share the same parent directory as VTK or ParaView, when you build VTK or ParaView it will automatically pick up the path to each of them. 2) For the library names, after modularization they've been changed and relocated from the bin subdirectory to the lib subdirectory. Many of the old libraries have been subdivided into better organized libraries. I don't know any specific document that specifies what to do for this though.

MPI is only used if it's available. It tries to see if there is a MPIController available.

Re: [Paraview] ParaView thinks that it does not have a wind blade reader
As far as the gradient filter is concerned: I pick the UVW array in the GUI. It does compute a gradient, but only for one array -- A-Scale turbulence (all variables are loaded). So picking a different array in the GUI doesn't seem to make a difference as it keeps computing gradient for that one input (point data) array. That's why it can't compute vorticity or q-criterion because a-scale turbulence is a 1-component array. Might be because I'm using an older version of the repo from late July.

Currently, this works only with structured data. If your data is structured, you can use vtkPStructuredGridConnectivity to generate a bitmask (an unsigned char associated with each mesh node). The bitmask can then be queried using the vtkGhostArray (See http://www.vtk.org/doc/nightly/html/classvtkGhostArray.html) to see which properties are turned on for the given mesh node. If the IGNORE property is ON, that means that the node is a duplicate with respect to the given process and should not be taken into account. The implementation assigns ownership to the lowest rank of a mesh node -- on all other processes, the IGNORE property is set to ON. TestPStructuredGridConnectivity illustrates how this can be used. The test ensures that: (1) Ensuring that the total number of nodes computed is invariant to the number of processes/partitions (2) Ensuring that computing the average for a given field is also invariant to the numer of processes/partitions If this could be useful in your work, I can elaborate more if you have any questions on how to use it.

[Paraview] Numpy masking (via programm filter) not quite working in parallel
Hi, I need to use Numpy in a lot of the programmable filters that I write, and I've run into differences in how its masking feature works in serial and parallel. Masking allows one to filter out portions of an array that do not pass some condition. As an example, I've created a stock paraview wavelet, and saved it as a pvd file. I then load it in, and run this inside of a programmable filter: --- import numpy data = inputs[0].PointData['RTData'] # create a mask that tells us which points are equal to one mask = numpy.ma.masked_equal(data, 1) # filter data array by the mask conditions (so that other points are excluded) maskedPnts = numpy.extract(mask, data) print len(maskedPnts) --- In serial mode, I get 9261 points. With two processes, I get 2 x 4851 or 9702. So masking always produces more points. Any ideas to why that is? Is there anything I can do/print out to see why masking doesn't quite work in parallel?

Re: [Paraview] Numpy masking (via programm filter) not quite working in parallel
Hi, I guess I forgot about the data duplication issue. For most statistics that I calculate in parallel, the basic results are not affected that much (i.e. mean, standard dev). But for the Pearson correlation coefficient, which is a bit more complicated, there is a noticeable difference (0.833 for parallel and 0.99 for serial). Will this point sharing information become available in later versions of ParaView? i.e. would it ever be easy to identify and count duplicates?

While ParaView splits the cells of a mesh across processes, cells on the boundary between processes share vertices. Thus if a vertex bounds cells split across 3 processes, that vertex will appear in 3 different lists of local vertices and thus be counted 3 times instead of once. There is nothing in ParaView for determining which vertices are shared (and by how many processes). This also affects the statistics filters when run in parallel on point-centered data. For most large data, the number of vertices on inter-process boundaries is small compared to the total so we documented the behavior for the statistics filters but did not implement a solution (because the expected skew is small).

Re: [Paraview] ParaView thinks that it does not have a wind blade reader
When running serially, vtkSMReaderFactory::CanReadFile sees that the session has a single process. As such, on line 660 it realizes that the source proxy's process support (in this case the source is a vtkWindBladeReader proxy) is multiple processes, which causes a return of false from that function. This makes ParaView think that the wind blade reader can't read a .wind file in serial. According to Andy, the reader works find in parallel. I assume that a fix for this is pretty trivial? It never did this before in previous versions of ParaView and I think that the wind blade reader code has remained mostly the same. Andy mentioned some details in person when he was talking with Jon but at that time I didn't know as much as I do now. There is a mention below about enabling the filter in serial and parallel -- is this done in a xml file?

Re: [Paraview] ParaView thinks that it does not have a wind blade reader
Well it seems like #1 and #2 can be solved by writing a new parallel wind blade reader class. I had similar experience by creating distributed versions of class that I created in other vtk directories. The normal wind blade reader would have no parallel calls, which would address #1. What I find interesting is that in your directories, the wind blade reader is located in VTK/IO/Parallel. For the ParaView snapshot that I downloaded, as well as the 3.14 source, it's still in VTK/Parallel. No Parallel folder in VTK/IO. Is this a recent change? So maybe the ideal folder layout would be: VTK/IO/WindBladeReader.* VTK/IO/Parallel/DistributedWindBladeReader.* I can make changes to the WindBladeReader to remove the MPI-IO calls and make a distributed wind blade reader class in case you want to add them to the repository. The one template I have for the parallel/serial split is the vtkStreamTracer and its distributed counterparts so I can use those as a guide. If you have better recommendations please let me know.

The problem was that vtkWindBlade reader was getting created to test CanReadFile and that would cause segfault unless MPI was initialized. Solved the problem by added support to vtkSMReaderFactory to respect the ProcessSupport flag on SourceProxy and change windblade reader XML to say that it only works in parallel. In other words, Windblade reader's Constructor should not take it upon itself to initialize MPI. Once that is fixed, we get to issue 2 before paraview 4.0 2) VTK's new modularization has the rule that no module can behave differently with parallel (or most other cmake config options) turned configured on or off. This is so because it makes it very hard to package VTK when the libs behave differently in different situations. Ie, we can't have any more #ifdef VTK_USE_MPI do something #else do something different #endif in VTK classes. Now if we want a class to behave differently when MPI is turned on or off we have to make a serial only version in a non MPI dependent module and a subclass of that in an MPI dependent module.

It had an explicit MPI call in the constructor that would cause problems when paraview wasn't getting built with MPI. Any time a user tried to open an unknown file it would try to create a windblade reader to see if the reader could handle the file and this would cause a crash. If you launch a separate pvserver the wind blade reader will be available in the gui. If someone fixes this problem in the reader we can enable it properly through the gui. Right now though I'm getting a bunch of warnings when running in serial like: Warning: In /home/acbauer/CODE/ParaView/ParaView/VTK/IO/Parallel/vtkWindBladeReader.cxx, line 942 vtkWindBladeReader (0x3a0c800): WindBladeReader error reading file: /home/acbauer/DATA/VTKLargeData/Data/WindBladeReader/test1_topo.wind Premature EOF while reading block of data.

Re: [Paraview] vtkDataSet algorithm that takes composite data set as input
This is my custom print self:

For some odd reason gdb does not allow me to step through vtkDataSetAlgorithm's
ProcessRequest. But it does return an error, as the executive prints the
following:
vtkPVCompositeDataPipeline (0x1dd7640): Algorithm vtkFastMarcher(0x1e2e9d0)
returned failure for request: vtkInformation (0x2d0d590)

It appears to fail in the superclass's ProcessRequest here:
// create the output
if(request-Has(vtkDemandDrivenPipeline::REQUEST_DATA_OBJECT()))
{
return this-RequestDataObject(request, inputVector, outputVector);
}
Basically RequestDataObject can't cast the inInfo into a vtkDataSet, because
it's a composite. I guess I have to override it?

I'ld sit down with a debugger and see which request exactly is failing and why.
Try overriding vtkAlgorithm::ProcessRequest() in your filter so that you can
easily get a breakpoint in an instance of your class.
In that method call PrintSelf(cerr, vtkIndent(0)) on the request
vtkInformation. Put the breakpoint right after that.
After the breakpoint call this-Superclass::ProcessRequest().
When the PrintSelf tells you which request fails, rerun and step in until you
see why the handling method returns.

Re: [Paraview] Data does not load off of a partition from saved (.wind) state
Addendum: What might help is to add another filter after the Field portion, like do a Gradient of Unstructured Data Sets and select UVW as the input. When you reload the state file you might notice that something goes wrong (i.e. UVW is not read in and an error message pops up).

Re: [Paraview] Linking error when trying to use vtkGLSL/vtkXMLShader
Thanks. That seems to do the trick. The only other issue is the rendering context. I've used the line integral convolution/lic filters as an example, and it seems like I need a SetContext function, which is passed a pointer to an (new) allocated vtkRenderWindow object. For reference, I am looking at vtkImageDataLIC2D.cxx. I will then need to downcast this object to a vtkOpenGLRenderWindow and pass it to vtkShaderProgram2, which requires a proper context...well I've done all of that, and so far I've noticed that a new (small, blacked out) window with the title Visualization Toolkit pops up when I start my filter. Now I have to do something with this fragment shader (which currently does nothing). Am I on the right track here? Or I am issuing an improper context?

Re: [Paraview] Unstructured to structured...
Thanks. I had a hunch that this was the answer. In my case, the surface would represent values that smaller than the requested iso-value, so inner cells would be below, while bordering cells would have points that are equal to and above. I needed to do the conversion because the paper specifically makes use of the iso-surface boundary in 3D space. I suppose I could have a multi-block data set with two data sets (using Group data sets): one unstructured (contour) and another structured (original). I could find out where the points of the iso-surface exist in the structured grid, although that part will take some thought.

In general, no. It is not possible to convert an unstructured grid to a structured grid because there are structures representable with unstructured grids that are non-representable with structured grids. For your question, it would be much easier to get the information you want by just looking at the scalar value on the original structured grid. You don't need to look at the isosurface. For example, all cells inside the isosurface will have all scalar values either above or below the isovalue (depending on the orientation of the surface).

[Paraview] Possible issue with velocity interpolator class
Hi, I've been developer a vortex core tracer, which is basically a customized version of vtkStreamTracer. I use the interpolation code quite heavily in the class, in this test case I use the point interpolator (i.e. vtkInterpolatedVelocityField class). Now in one part of the code, I've noticed that doing two calls to the interpolator's FunctionValues for a bad boundary point produces strange results. After the first call to FunctionValues I obtain a valid cell (using GetCell) and after the second call I get a NULL cell. The second call is correct because the point in question's y coordinate is -0.0012773338068285955, which outside of the data set's 0-boundary. Anyway, I will look into this further to see what's up; I was wondering if anybody has ideas.

Re: [Paraview] Interesting bug when using windbladereader and multiple time steps
Hi, There is actually another bug (which may or may not be related) which did not happen before with ParaView 3.8.0 but appears with the release branch of the ParaView that I am using. If I load a wind data set after connecting to 2-process localhost (mpirun -np 2 pvserver), the gradient of unstructured grid appears greyed out in the filters menu so I can't use that (which is necessary for me). If I run mpirun -np 1 pvserver, this is not an issue. It's only an issue with 2 processes or above. This doesn't happen if I load in a *foam file (i.e. openFOAM file); only with .wind and the most up-to-date release version of ParaView as opposed to 3.8.0.

[Paraview] Getting a raytraced picture from Manta
Hi, I have been able to get Manta raytracer to compile with paraview and load in as a plugin. I even see the extra GUI options in the display tab of certain filters like the Tube filter. I'm just wondering how to get something raytraced as a result. I did a bit a research via the list and found a page that says that I must start the paraview server with the plugin loaded. The client would also have the plugin loaded and connect to the server. The instructions didn't say how to do that on the server side . Usually when I start the paraview server (pvserver), it does not launch the GUI but just waits for a client connection in the terminal. So I don't know how to load the plugin on the server...the command line options for pvserver didn't provide any hints. Please advise.

Re: [Paraview] Getting a raytraced picture from Manta
Thanks. It turns out that I am working with an older version (3.8.0) since I am making preparations for a paper (due next week) and some code hasn't been ported to latest version yet. I basically have to add the plugins in the Remote plugins section o fthe Plugin manager. The plugin's a bit buggy and causes a crash, however, and I think that may be due to the fact that I am using an older version of Manta.

Then any object that you create will be shown in that raytracer view... And with the latest implementation, you don't need a remote server anymore.

Re: [Paraview] Using streamtracer/gradient filters on multi-block data set
Hi,
So the reason why my required filters are greyed out after loading this CAS
data set is due to a few lines in the XML file. The streamtracer is an example:
DataTypeDomain name=input_type composite_data_supported=1
DataType value=vtkDataSet/
/DataTypeDomain
InputArrayDomain name=input_array attribute_type=point
number_of_components=3/
Now I did introduce a vtkStructuredGrid into the pipeline, which inherits
from vtkDtaSet, so that shouldn't be a problem with the DataType portion
above. But what concerns me the InputArrayDomain requirement. By default
the data set loads in a bunch of 1-component arrays. I thought that by
creating the 3-component UVW array (see below), I wouldn't face any issues.
But for some reason I still do -- maybe that requirement is unfulfilled?
If anyone has any ideas, please let me know.
Sohail

Not sure what you mean by that last statement -- do you mean transfer an array
to pointdata? I tried to do this:
input = self.GetInput()
output = self.GetOuput()
output = vtk.vtkStructuredGrid()
output.ShallowCopy(input.GetBlock(0))
// create UVW array (3-component velocity array)
output.GetPointData().AddArray(UVWArray)
When I print output, I do see the added array in the point data section with
the correct component and tuple count. However, the bounds of the grid are
suspect (like -0.1 to 0.3 for x; -0.1 to 2.6e-18 for y) and the grid extent is
0, -1, 0, -1, 0, -1.
I also tried:
#yiv1702808980 p, #yiv1702808980 li
{white-space:pre-wrap;}output.GetPointData().SetVectors(UVWArray)
Didn't work either. Something is still not right here...

[Paraview] Using streamtracer/gradient filters on multi-block data set
Hi,
I've read in a CAS file, which Paraview read in a Multi-block dataset, which
contains within it a unstructured grid.
Initially I had a problem where all of the data items were one-tuple arrays.
So I created a UVW (3-tuple velocity) array and added it to the pipeline this
way using a Python programmable filter:
input = self.GetInput()
output = self.GetOutput()
output.ShallowCopy(input)
create array here***
output.GetBlock(0).GetCellData().AddArray(UVWArray)
Note that GetBlock(0) gives me access to the grid object. For some reason
the gradients and streamtracer filters were greyed out and unavailable. So I
decided to make the output variable a vtkUnstructuredGrid instead and
transferred the UVW array to it this way:
p, li { white-space: pre-wrap; }output.GetPointData().AddArray(UVWArray)
Nope...didn't work. Any thoughts how I can modify the pipeline so that the
streamtracer and gradients of unstructured data sets array can become usable?
I'm guessing there is something in those classes which tells Paraview that they
require certain input types. I've seen references to stuff like
FillInputPortInformation.
Thanks,
Sohail

By any chance, does this multi-block dataset contain a block that does not have
arrays (scalars and/or vectors)? That's probably why those filters are
disabled. You can always use Extract Blocks to extract the block you are
interested in and then apply the filter. As for the Programmable Filter, if you
set the output type to vtkUnstructuredGrid, you should be able to do:
self.GetOutput().ShallowCopy(self.GetInput().GetBlock(0))
assuming that block 0 is a uns. grid.
