[Paraview] Access to the renderer
Hi all, I'm looking for a way to get use vtkSelectVisiblePoints within a C++ filter in ParaView. Outside of ParaView, we have generated working VTK code that creates a renderer and renderwindow, sets up a camera, adds mappers and actors and passess the renderer onto selectvisiblepoints. We'd like to do all this within ParaView so should be able to pass the ParaView renderer to MySelectVisiblePoints-SetRenderer(x). Can anyone suggest a solution?

For the 3.10 release, we have added 60 new readers. The new readers include: ANSYS, CGNS, Chombo, Dyna3D, Enzo, Mili, Miranda, Nastran, Pixie, Samrai, Silo, and Tecplot Binary. A full listing of supported readers can be found in the ParaView Users Guide. We also added the ability for developers to create ParaView reader plugins from previously developed VisIt reader plugins. You can find a full guide on how to do this on the VisIt Database Bridge: http://www.paraview.org/Wiki/VisIt_Database_Bridge With this release we have rewritten the ParaView User's Guide and are making it freely available for the first time. The complete guide can be obtained in the help system or online at: http://paraview.org/Wiki/ParaView/Users_Guide/Table_Of_Contents. We have included a Python-based calculator which makes it possible to write operations using Python. The Python calculator uses NumPy, which lets you use advanced functions such as gradients, curls, and divergence easily in expressions. Also the NumPy module is packaged in the ParaView binary and is importable from the ParaView Python shell. There should also be a marked performance improvement for users dealing with large multi-block datasets. We have cleaned up the rendering pipeline to better handle composite datasets, avoiding the appending of all blocks into a single dataset as was done previously. To better utilize multiple cores on modern multi-core machines, by default ParaView can now run using a parallel server, even for the built-in mode. This enables the use of all the cores for parallel data processing, without requiring the user to start a parallel server. ParaView binaries will also be distributed using an MPI implementation, making this feature available to users by simply downloading the binaries. Since this is an experimental feature, it is off by default, but users can turn it on by checking the Auto-MPI checkbox in the application settings dialog. Additionally, the 3.10 release includes several usability enhancements. 3D View now supports smart context menus, accessed by right-clicking on any object in the 3D View to change its color, representation, color map and visibility. Left-clicking on an object in the 3D View makes it active in the pipeline browser. Within the spreadsheet view, sorting is now supported and an advanced parallel sorting algorithm ensures that none of the benefits of the spreadsheet view, such as streaming and selection, are sacrificed. Python tracing and macro controls are no longer hidden on the Python shell dialog and instead are now easily found on the Tools menu. For developers interested in adding support for advanced multi-pass rendering algorithms to ParaView, this release includes a major refactoring of ParaView's rendering pipeline. View and representations have been redesigned and users should see improved performance in client-server
Re: [Paraview] Access to the renderer
The short answer is you cannot do it. In ParaView logically filters are on data-server and renderers are on render-server. The abstractions provided by ParaView hide these components so that such things are very difficult to do. For the longer answer, it'd help if you can describe why you want to call select visible points in your filter?

Re: [Paraview] loading nc formatted data
Hi Simon, Replies below...

As you can see, the grid is correctly loaded. But in the data, there is a crack. Is there a filter that can fix this in ParaView? :) I'm not aware of any filter that will fix this automatically. Can you describe the grid a bit more? It kind of looks like a multiblock of structured grids. ftp://ftp.gfdl.noaa.gov/pub/sms/4ParaView/4.png is the latest nc file that I have of similar simulation preprocessed output. When I loaded it up, it is clearly doing making assumption on the grid that is not correct and hence, the double looking grid. The questions now are: 1. ParaView has lots of *.nc file loader. How do I know which loader is ParaView using to load the data? If I pick a type for the Files of type option in the open File window, will that gurantees that ParaView will be using that particular file loader? If there is an ambiguity for which file loader to use (i.e. multiple readers assume the same extension), then the GUI should pop up a dialog for you to specify which one to use. You can use the python trace to figure out exactly what reader is being used to load the file. 2. If I know which loader is used, I would like to see if I can modify the existing loader to create a new type of *.nc file loader to fix the grid of my data. Where is the code in the source tree of ParaView is the loader plugin placed? Based on the name of the name of the reader from the python script, you can look up the actual class name in the ParaView/Servers/ServerManager/Resources/readers.xml file. or if there is an easier solution to fix my grid problem that doesn't involve developing a new data loader plugin that would be better :) please let me know... thanks -simon ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview

Re: [Paraview] Applying filters in sample app
Michael, The interactive-widgets such as implicit plane widget are created by the Properties panel to help user change some of the properties for the filter. So yes, if your example, you will not see the implicit plane widget at all. You'll have to manually create it and set it up to update the properties of the clip filter as the user moves it. It can be a bit tricky. But maybe I can hack up some code in your example to show the implicit plane if you'd like.

My guess is that some library rodata is getting built without the -fPIC flag. If you built that yourself then you should rebuild that with that compile flag.

It kind of looks like a multiblock of structured grids. ftp://ftp.gfdl.noaa.gov/pub/sms/4ParaView/4.png is the latest nc file that I have of similar simulation preprocessed output. When I loaded it up, it is clearly doing making assumption on the grid that is not correct and hence, the double looking grid. The questions now are: 1. ParaView has lots of *.nc file loader. How do I know which loader is ParaView using to load the data? If I pick a type for the Files of type option in the open File window, will that gurantees that ParaView will be using that particular file loader? If there is an ambiguity for which file loader to use (i.e. multiple readers assume the same extension), then the GUI should pop up a dialog for you to specify which one to use. You can use the python trace to figure out exactly what reader is being used to load the file. 2. If I know which loader is used, I would like to see if I can modify the existing loader to create a new type of *.nc file loader to fix the grid of my data. Where is the code in the source tree of ParaView is the loader plugin placed? Based on the name of the name of the reader from the python script, you can look up the actual class name in the ParaView/Servers/ServerManager/Resources/readers.xml file. or if there is an easier solution to fix my grid problem that doesn't involve developing a new data loader plugin that would be better :) please let me know... thanks -simon ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview

Re: [Paraview] loading nc formatted data
The reader that is being used is vtkNetCDFCFReader. It is defined in
ParaView/Servers/ServerManager/Resources/readers.xml, although it is not
obvious.
As the name implies, this reader reads netCDF files using the CF convention.
(As the default netCDF reader, it also gracefully handles files that do not
follow this convention.) With this assumption, I will try to explain what it
does. It reads arrays as regular 1, 2, or 3D arrays, possibly with time. The
CF convention also provides a means to assign coordinates to each grid point
and to identify the coordinates as longitude or latitude.
Even though coordinates are defined as longitude and latitude, the topology of
the grid itself is still a grid. Thus, the grid gets wrapped around, but still
has these seems that you see because topologically the one end of the regular
grid is not attached to the other. I can't think of any filter that will
identify and close these seems. In fact, it's not straightforward to do at
all. If you look at your topology, it is not lain out on a simple spherical
grid.
The right way to solve your problem, which may or may not be in your control,
is to create netCDF files that specify cell boundaries for a closed topology.
Your netCDF file must be following at least some parts of the CF convention;
your data would not show up as a sphere if it were not. The CF convention
provides a way of defining cells that are not constrained by a regular grid
topology. It is done through a bounds attribute on the dimension descriptor
variables. You need either 1D or 2D bounds. They are described in this
section of the CF convention documentation:
http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.5/cf-conventions.html#cell-boundaries.
The VTK test data has examples of both 1D bounds (tos_O1_2001-2002.nc) and 2D
bounds (sampleCurveGrid4.nc). You can get the VTK test data from git
(http://vtk.org/VTKData.git), or download them directly from the gitourious
server:
