[Paraview] Labelling Cell Data
Hello All, I am currently writing a plugin for ml labelling purposes. I split different volumes into slices, grid them, and label them. I currently use the properties panel one grid (pixel) at a time (which for time purposes isn't the best obviously). Is it possible to incorporate ParaView's Selection Widget to get the cells that are currently highlighted in order to change their cell labels? Thank you, Kevin E.

(These are truth coordinates for SVMs and Convolutional Neural Nets) So if I am to adjust the position of the object within the SceneID, I would like for those new coordinates to be dispalyed in the Properties Panel. But most of the properties will probably be information only.

[Paraview] ParaView numpy interface question
Hey all, I have a quick question about setting scalar values with the python macro inside paraview. So I have two images that I want to do scalar manipulation with. *example code:* from paraview import simple from vtk.util import numpy_support as npvtk import vtk.numpy_interface.dataset_adapter as dsa import pandas as pd import vtk scaling_vti = simple.XMLImageDataReader(FileName=[scaling_filename]) scaling_rawData = simple.servermanager.Fetch(scaling_vti) scaling_data = dsa.WrapDataObject(scaling_rawData) scaling_array = pd.DataFrame(npvtk.vtk_to_numpy(data.GetPointData().GetScalars()), columns= ['scaling_error']) humans_vti = simple.FindSource(humans_filename) humans_vti.PointArrayStatus = ['Scattering Density'] humans_rawData = simple.servermanager.Fetch(humans_vti) humans_data = dsa.WrapDataObject(humans_rawData) humans_array = pd.DataFrame(npvtk.vtk_to_numpy(humans_data.GetPointData().GetScalars()), columns=['scalar_intensity']) new_scalars = pd.DataFrame(humans_array.scalar_intensity * scaling_array. scaling_error) data.GetPointData().SetScalars(npvtk.numpy_to_vtk(new_scalars)) After I do this, I can bypass the pipeline (because I haven't figure out how to use it yet) by writing this image to a new file then load it again to render it. Is there a way I can set the paraview image with the new scalar values and have it render without having to write it to a file first? Or, is there a way to convert the vtk.numpy_interface.dataset_adapter.DataSetAttributes type back to paraview.servermanager.FieldDataInformation? Thanks, Kevin E.

[Paraview] QLineEdit & proxy()->InvokeCommand()
I am writing a plugin that, theoretically, should be able to change inputs
as I apply them through a QLineEdit. The file that I am using to create the
UI portions of the plugin is similar to that of the PointCloudLibrary.
However, I was wondering if there is a way to pass along the "changed
value" to the command I want to invoke?
Here is a snippet of what I am doing:
##
connect_to_dds.h
##
QLineEdit* xmin = new QLineEdit("XMin");
this->connect(xmin,
SIGNAL(textChanged(QString&)),SLOT(setXMinValue(QString&)));
layout->addWidget(xmin);
public slots:
void SetXMin(const QString& text)
{
vtkSMSourceProxy* sourceProxy =
vtkSMSourceProxy::SafeDownCast(this->proxy());
if (!sourceProxy)
{
return;
}
sourceProxy->InvokeCommand("SetXMin");
}
###
Image_Reconstruction_DDSReader.cxx
###
void Image_Reconstruction_DDSReader::SetXMin()
{
// double XMin = ;
}
Is there a way to pass along the changed value within the Proxy? Or is
there a better way of doing this?

Re: [Paraview] Conversions
Thanks Cory, that did get me a little further. However, at the moment, I am trying to stream (multiple) vtkPolyData Objects. For Some reason, I can't get them to update by pieces/blocks (i tried referring to http://www.vtk.org/Wiki/VTK/Streaming http://www.kitware.com/blog/home/post/797). So I ended up converting them to vtkImageData (but could only load one of the two). I put them into a vtkAppendFilter() and converted them to a structured grid and Utilized vtkStructuredGridAlgorithm. I can visualize either the entire block which contains the two separate Objects, or the points of each object instead of the Surface Representation of each block. I'll keep trying to figure it out :-), I'm getting closer (and this helped so thank you). Thanks, Kevin On Thu, Jul 23, 2015 at 6:05 PM, Cory Quammen cory.quam...@kitware.com wrote: Hi Kevin, Here's one way you can get a structured (actually uniform rectilinear) grid from an unstructured grid: - start ParaView - load your unstructured grid - create a Wavelet source with the extent set to the extent of your desired structured grid - Filters - Resample With Dataset.

Ok, so I looked through this yesterday and tried implementing some of the
code. I now have the poly data information (# of cells, # of points, and

(and their data arrays to be copied to the output), is the best way to set
the update extents by:
executive-SetUpdateExtent( vtkInformation *, int piece, int numPieces,
int ghostLevel );
I'm not that familiar with updating unstructured datasets. Image data is
simple because the extents are based off the size of the image. Also, for
understanding the description of pieces, since they are subsets of
unstructured datasets, does a piece correspond to individual cells or other
information held within the poly data? And just one more question, is there
a good place to find an explanation of what is / how to set up a PRODUCER,
because I read that the producer determines what a piece means...
Thanks for the help!

Re: [Paraview] Update Request Data / Information
Ok, I figured out how to update the Pipeline. However, I now have another interesting problem. I can't see the volume view update automatically. I have to switch between Volume View and Outline View (for example) in order to see the updated image. Is there a way to update just the volume view? Thanks. Kevin E.

[Paraview] pvserver
Hey, How's it going? I am currently trying to figure out how to acquire real-time image reconstruction updates across a cluster configuration. I have several reader (plugins) that convert from my types to vtk types. I have also utilized pvserver minimally; but should it be able to read/handle data that is being published to a specified port? Also, I will probably have to create a communication layer that handles CoreDX DDS communication. Would it be proper to create this layer as a plugin or do I need to link it to some pvserver backend?

[Paraview] Utilizing ParaView Server
Hey what's up? I have a couple questions about using ParaView server? 1. I have figured out how to connect to the localhost as an example. I am trying to understand/figure out how paraview can actually update live images once data is being published to whatever port is specified? Is there any documentation that you can lead me to? I'd appreciate it. 2. Also, I have to deal with CoreDX DDS socket communication. Is there any support with that from ParaView or is there a way to create a plugin that can manipulate the middleground between my types and paraview's types over the server? Thanks again Guys!

[Paraview] Switching Between Readers
I was wondering if there was a way to instantiate a superclass that, let's say, can switch between vtkPolyDataAlgorithm and vtkImageAlgorithm. I have a reader that (as of now) converts the data within a protobuf file to image data. But currently, I have multiple protobuf files with different information. However, the file extension is still .pbuf, and it seems that the reader xml parsers the files based off this input. So would it be easier to change the filename? Or is there a way to switch between the two algorithm classes? Thanks for your time! Kevin E. Dean -- This email and its contents are confidential.
