Re: [Paraview] Catalyst distributed graph example

[Jeff Baumes]

vtkMutableDirectedGraph

has an API that is hopefully pretty intuitive with AddVertex, AddEdge, etc.
You can also shallow-copy from the mutable graph into a DAG object, which
performs a check, if it is important to verify you made a proper DAG. From
the vtkDirectedAcyclicGraph docs
 (I
noticed some typos here, should read "DAG" instead of "tree"):

=
vtkDirectedAcyclicGraph is a read-only data structure. To construct a tree,
create an instance of vtkMutableDirectedGraph. Add vertices and edges with
AddVertex() and AddEdge(). You may alternately start by adding a single
vertex as the root then call graph->AddChild(parent) which adds a new
vertex and connects the parent to the child. The tree MUST have all edges
in the proper direction, from parent to child. After building the tree,
call tree->CheckedShallowCopy(graph) to copy the structure into a
vtkDirectedAcyclicGraph. This method will return false if the graph is an
invalid tree.
=

As for rendering in ParaView, you the following example shows how to use
vtkGraphToPolyData, but this is not exposed in ParaView to my knowledge, I
think you would need a plugin, or preprocess the graph into a vtkPolyData,
save it, then load into ParaView.

https://www.vtk.org/Wiki/VTK/Examples/Cxx/Graphs/GraphToPolyData

Embedding from higher-dimensional coordinates into 2D or 3D does not have a
VTK implementation that I know of, though PCA in VTK may be able to be
used. If you want to do layout based on edge connectivity, there are some graph
layout algorithms
 in
VTK that could get you 2D or 3D coordinates.

FWIW, Titan (titan.sandia.gov) has a vtkHDF5TableReader. It can find a
single hdf5 dataset containing records and store it in a vtkTable. It is
certainly limited, but people are free to enhance it. As Dave said, hdf5 is
so complex I'm not sure how generally useful it can become. Right now it
reads what I'm sure is a small subset of what could possibly be in hdf5.

Re: [Paraview] visualization of neural network activity

[Jeff Baumes]

VTK/Titan may have most of the components that you need, but they are not
currently available in ParaView. Titan (titan.sandia.gov) has a generic hdf5
reader that loads data into a vtkTable that may suit your needs. There are
also utilities for converting a vtkTable into a vtkGraph which can then be
visualized in vtkGraphLayoutView, which can do 2D or 3D layout. As far as
animation goes, graph layout on time-changing graphs is a tricky problem
since it's easy to lose your frame-of-reference if you redo layout each
time. But if you want to do the layout once, fix the node positions, then
just animate properties like colors, that is more doable.

The other option is to manually get the data into one of the several
geometry formats ParaView supports, then you could use ParaView directly.
For example, you could produce a legacy vtkPolyData format where you define
neurons as points and connections as lines, then you load it in ParaView and
do things like glyph the points with spheres, color lines by attributes,
etc.

I believe all the entries in the data menu are part of the Infovis plugin.
Verify that PARAVIEW_BUILD_PLUGIN_Infovis is on. If it already is, my next
assumption is that the plugin does not load correctly ... you can try
manually loading it from the Manage Plugins dialog and see what happens.

SetPipelineInformation will cause the information object to increment the
reference count of the data object. Thus calling Delete will safely
decrement the reference count without yet releasing the memory (this matches
the reference created by NewInstance()). This is necessary or else a
reference will be floating and the object will never be deleted.

Re: [Paraview] SQLite to XY Plot

You would create an instance of vtkSQLiteDatabase and point it to your
sqlite file. You set that as the database in vtkRowQueryToTable.
ParaView's vtkCSVWriter allows you to write this table as a .csv file,
which ParaView can read directly. You should be able to load a
2-column table into the existing chart view.

If you feel adventurous, you can compile from CVS with
PARAVIEW_BUILD_OverView on. This will build a set of plugins for
ParaView, one of which is a SQL Table Reader. You can run paraview and
load the related plugin manually. This enables ParaView to directly
read from sqlite, along with other SQL database types.

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);
}

Sandia National Labs and Kitware are in the midst of making it
possible to store and process very large graphs in distributed memory
using vtkGraph and the Parallel Boost Graph Library. Some of this is
currently in VTK, but it is not yet incorporated into ParaView. Your
other choice which may work for you is to use vtkPolyData with line
cells, since some of the operations you are talking about exist in
ParaView for polygonal geometry, although I don't know the exact
sequence of filters you would need for your use case. ParaView also
has the notion of multi-block data sets which can group assoicated
data sets into one object.

Should read "does not yet support VTK infovis classes (vtkTable,
vtkGraph, vtkTree)."

The legacy reader for paraview/overview does not yet support VTK classes.

> I also tryed to create a plug in for vtkTreeReader

Your reader plugin looks close to correct, and should appear in the
menu. Does your plugin appear in OverView under Tools -> Manage
Plugins ?
You can also try adding

  SERVER_MANAGER_SOURCES ${VTK_SOURCE_DIR}/IO/vtkTreeReader.h

to your ADD_PARAVIEW_PLUGIN command. You can look at Plugins/Infovis
to see how other infovis readers are added to the list.

[Paraview] OverView application in ParaView

[Jeff Baumes]

Over the past year or so, the Titan informatics project led by Sandia
National Laboratories has been developing informatics plugins for
ParaView. These include a network view, a geospatial view, and many
other informatics and statistics filters and views. These plugins,
along with a thin client application called OverView, will be migrated
into the ParaView repository early next week. The new application and
plugins will default to off, so the effect to normal ParaView
checkouts should be minimal. However, there may be some hitches along
the way, so I wanted to give a heads up that ParaView CVS head may not
be stable for a few days starting next Monday. The Titan project
homepage is

https://www.kitware.com/InfovisWiki/index.php

A wiki page briefly outlining what will be moved to ParaView is at

https://www.kitware.com/InfovisWiki/index.php/OverView_Migration

When things settle down, we will send out detailed instructions about
how to try out this new application.
