[Paraview] Some tests and questions about PV 3.10.0-RC1
Hello, all. I have just downloaded the PV-3.10.0-RC1 Linux 64 binaries and it works fine. I Could not find the VisIt plugin in the Tools-Manage plugins menu, but I suppose it is now fully integrated in PV? However, I was able to read Tecplot files, and I could also load the LIC plugin. For all and Adriano Gagliardi: I said in a previous mail that the VisIt Tecplot reader in Linux PV 3.8.1 was not working on my new CentOS 5.5 workstation. This problem is now solved with PV 3.10.0-RC1: both proposed Tecplot Readers, Tecplot and Tecplot(VisIt), are working fine. Now I have just a question about rendering. When I rotate or zoom an object, the object rendering is coarse as in previous PV versions, but it remains coarse for a few seconds when I release the mouse, and I see a countdown in the bottom left of the window: Full resolution render in : xx seconds. This is not very important but just a little bit annoying. Is there a parameter in the settings that could reduce this rendering time?

[Paraview] .plugins file - Give a path ?
Hi, Is it possible to point the path to a .xml file in the ~ParaviewDir/bin/.plugins file?

[Paraview] Function limitation/bug?
Could it be that the Xdmf Function DataItem cannot handle more than ten operands? The sample file quoted below will load just fine into Paraview (3.8.1 64bit Linux) as long as the formula operates on any of the first ten (i.e. $0 through $9) DataItems. However, changing Function=10 + $9 to Function=10 + $10 in line 22 will cause a segfault. The obvious workaround is to use nested Function items for formulas involving more than ten operands. I'm just wondering if this is a genuine bug, or if maybe the 11th item has to be referenced by something else than $10? Comments (especially from the developers) would be much apprechiated.

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1
Thank you for the answer, Robert. The Tecplot reader works fine with a single file that contains a multi-block dataset, but I encountered a problem when trying to read the same data as a serie of Tecplot files. Each file is a single block surface grid on the skin of an aircraft. Once I had selected all my files, I got an error message: Group name and proxy must be non empty. But this was only a warning and PV was always running. Then I had to choose between Tecplot Files (VisIt) and Tecplot Files in the Open data with.. window and click OK for each file in my serie. Each time I clicked OK, a new file was loaded in the pipeline, but as I had selected more than 350 files, I decided to cancel. But the Cancel button is ignored and the Open data with.. window appears again and again! The only way to cancel the reading task was to kill Paraview. I hope that this could be solved in the final release. Now may I suggest an improvement for all readers? When reading huge datasets, the screen seems to be frozen (for about one minute with my full aircraft CFD dataset), and it would be nice if we could have in a future release some progress bar or something else indicating that PV is always alive. Best regards and good week-end. Richard.

[Paraview] Function limitation/bug? (another one!)
From [http://www.xdmf.org/index.php/XDMF_Model_and_Format] regarding the Xdmf Function DataItem: The function description can be arbitrarily complex and contain SIN, COS, TAN, ACOS... However, I noticed that operations as simple as multiplication by a constant are tricky: In Paraview 3.8.1, Function= 2.3 * $0 will apparently multiply the DataItem referenced by $0 by the _integer_ part of the constant factor (2.0 in this case)! This is especially nasty if you plan to multiply by something between 0 and 1, which will consequently reduce all values of $0 to zero. The same seems to apply to *division* by a non-integer constant. A multiplication by, say, 1.5 can be achieved using something like Function= $0 * (3/2) or Function= ($0 / 2)*3 . Note also that things like Function= (1.2+0.1) * $0 will segfault (at least on my machine). The XMDF file quoted below may serve to illustrate this issue. If this problem can be confirmed, I propose to at least add a corresponding comment to the XDMF wiki.

[Paraview] ANN: ParaView 3.10.0 RC-1 Available for download
Hello All, The ParaView team is pleased to announce the availability of the ParaView 3.10.0 Release Candidate 1 binaries for download on the ParaView download page. The 32bit Linux binary is still missing after a package generation snafu but will be available shortly. Also, Final 3.10 binaries should be available within the next week or two if all goes well. http://paraview.org/paraview/resources/software.html Release Notes: ParaView 3.10 This release features notable developments, including mechanisms to incorporate advanced rendering techniques, improved support for readers and several usability enhancements and bug fixes. 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 makes it is possible to use advanced functions such as gradients, curls, and divergence easily in expression. 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 mutli-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 now exposed from the main menus, no longer hidden under the Python shell. For an exhaustive list of the new features and bug-fixes, please refer to the change log at: http://www.paraview.org/Bug/changelog_page.php. 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 mode from reduced interprocess communication during rendering. LANL's MantaView interactive ray tracing plugin has been restructured to make it easier to use. Version 2.0 of the plugin is now multi-view capable and no longer requires ParaView to be run in a client/server configuration. Similarly both of LANL's streaming aware ParaView derived applications have been merged into ParaView proper in the form of a new View plugin. The underlying streaming algorithms have been rewritten to be more usable and extensible. Both plugins are available in standard binary package for the first time in this release. As always, we rely on your feedback to make ParaView better.

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1
Hi Richard, In the 3.10 we have introduced the ability to load multiple files when using the ctrl and shift keys. If you want to load a file series you need to select the file series root node, not each item in the series. Doing so will make ParaView load each file individually. You can find a nice guide to loading files in the user guide: http://www.itk.org/Wiki/ParaView/Users_Guide/Loading_Data http://www.itk.org/Wiki/ParaView/Users_Guide/Loading_Data On Fri, Feb 4, 2011 at 10:03 AM, Richard GRENON richard.gre...@onera.frwrote: Thank you for the answer, Robert.

Re: [Paraview] Some tests and questions about PV 3.10.0-RC1
Hi Richard, I've just talked to Rob about your problem and explained your point. Rob is going to report a bug for that. One solution we were thinking of is when several files are selected in the OpenFile process, if we already have define a reader for a given extension, we reuse that same reader and ask for the reader type only for new extension where concurrent reader exist. What do you think ?

[Paraview] paraview crashes on obj file originating from VMD
Hello We need to export molecular structures and surface renders from UIUC's VMD to OBJ with color/material support into Paraview for use with VisBox. Paraview 3.8.1 and 3.10-RC1 both crash while trying to render the OBJ files here: http://cesium.hyperfine.info/~cowbert/vmd/vmd1.obj http://cesium.hyperfine.info/~cowbert/vmd/vmd1.mtl Segfaults after hitting 'Apply'. Furthermore I read somewhere that the vtk OBJ reader does not read or process MTL files? Is this something that can be fixed? We'd really like surface colors and transparency to be imported from the mtl file... Also Paraview will also crash reading in VMD output to VRML2 with a segfault: http://cesium.hyperfine.info/~cowbert/vmd/vmd1.wrl The VMD developers at UIUC are certain these are problems with Paraview and not their software... One final method might supportable is: output POV-Ray from VMD and then convert it to something that Paraview will read. Any ideas on that? Thanks -- === Peter C.
