[Paraview] comparison of two dataset (same mesh ) but not in the same order
Hi, One of my student is validating his code, and we want to compare the results (point data, cell data). We have two result: one from a commercial code, and the other from our code. The dicretisation are the same: same number of node, same number of element. But the order of the node and element in the files are not the same, so we cant use append attributes. For for the point data we use re-sample with dataset. But the problem is than the celldata is automatically converted to point data (I know there is no definition of re-sample with dataset with cells in the source). So my question is Is there an easy way of sorting the point and cells so they have the same order for the two datasets so I can use append attributes? A sort of clean to grid that also apply a unique order to the point and cells.

Re: [Paraview] Controlling Render Views without Mouse
Hi, I tried to control my paraview from my Xoom tablet, throw plugin successfully. I used a plugin that opens a port and listen to python commands, then from my tablet I send python command to rotate zoom, pan clip... (so now a have a realy big pad ;) ). for more information read: http://www.paraview.org/pipermail/paraview/2012-January/023704.html Felipe On 29/05/2012 07:23, David Zemon wrote: Hello, *Overview* I am attempting to control ParaView v3.14.1 with something other than a mouse and keyboard. I don't know how to do this - I've taken some wild guesses and bits 'n' pieces have started to work. I could really use some help from someone that knows the inner-workings though. *What I'd Like to Happen* I have an class, foo, with some events and callbacks of its own. Foo is not related to ParaView in any way other than foo needs to make ParaView do stuff as it sees fit. In the callbacks, I'd like to do things like zoom, pan and rotate. Eventually I'd like foo to be able add filters and such too, but that's a long way down the road. *What I've Tried* foo has 3 events similar to OnButtonDown, OnMouseMove, and OnButtonUp. I figure, why not just call these methods (within vtkPVInteractorStyle) from foo? This is what I've been trying. I have made foo a friend of vtkPVInteractorStyle. I've created a global pointer variable, g_pInteractorStyle, which points to vtkPVInteractorStyle. I've created a mutator and two integer variables - m_x and m_y - within foo to hold mouse coordinates. Any time that GetEventPosition()[0/1] is called, I save those values to local variables - x and y - and pass them into foo's mutator. This way, any time a real mouse is used, foo gets updated coordinates. This also now gives me starting points to pass into OnMouseMove. From foo I first call g_pInteractorStyle-OnButtonDown(3, 0, 0). Ideally, this will initiate zoom, which it seems to. Following that, I make a series of calls following the pattern: g_pInteractorStyle-Current-OnMouseMove(m_x, m_y + /offset/, g_pInteractorStyle-CurrentRenderer, g_pInteractorStyle-Interactor), where /offset/ is some integer value from -49 to 49 and neither m_x or m_y change during the series of calls. Finally, I call g_pInteractorStyle-OnButtonup(3). I have also commented out one line each from OnButonDown and OnButtonUp: this-InvokeEvent(vtkCommand::[Start/End]InteractionEvent). With these two lines in place, OnButtonUp causes a crash. Without these lines in place (when they're commented out), ParaView acts just fine. I know this is NOT a good fix and I'm open to other suggestions, but it (this aspect) seems to be working at the moment. I've also tried looking into the QT libraries and moving the cursor via QT. Unfortunately, I've been unable to find the right cursor because nothing I've done has had any effect on the cursor I'm staring at (tried setPos() and setShape()). *The Problem* OnMouseMove() has caused problem after problem. In our current setup OnButtonDown(3, 0, 0) works great. OnMouseMove() kills paraview when it reaches vtkPVRenderView::Render() called from somewhere within vtkPVGenericRenderWindowInteractor. In a weak attempt to fix the problem, I tried commenting out this Render() call. Nothing too major seemed to break except that I'm blind as i try to zoom until I release the mouse button (tests were done using the mouse at first). In other words: Everything still working, but no rendering during zoom - only renders upon releasing the mouse. I now try it with foo, and it acts as though OnButtonUp(3) was never called - the whole foo routine finishes then I use the mouse and click somewhere to start a new interaction, and it zooms to wherever it should have zoomed when it finished foo's routines. So two options: I can either let it die every time it tries to render, or hold off rendering until I finish moving the mouse and then still be required to click the mouse somewhere when I'm finished. This is broken. And something tells me I'm going about this in a very wrong fashion. How should I be doing this?

Re: [Paraview] comparison of two dataset (same mesh ) but not in the same order
I don't think such a filter exists in ParaView. You'll have to write a custom filter or a Python programmable filter to convert one of the datasets to the same point/cell order as the other.

Re: [Paraview] comparison of two dataset (same mesh ) but not in the same order
I would go so far as to say that there probably is no easy way to find consistent ordering of topology. In fact, I suspect that this is an NP-hard problem. (General graph isomorphism certainly is.) I would first pursue other resampling methods. You could apply the cell centers filter to the grid with cell data. That gives you a cloud of points at the center of each cell. The distinction between cell and point data is now in name only. Then, resample the point data grid with the cell centers. That will give you the point data interpolated to the cell centers. -Ken Sent from my iPad so blame autocorrect.

Re: [Paraview] Color surface by normal direction (inwards or outwards)
Lorenzo, Yes, you can do this. Under the Display tab, choose the color of the front face in the Color control panel. Set the Color by option to Solid Color, then pick the color you want with the Set Solid Color... button. Then scroll down almost to the bottom of the Display tab. There is a Backface Style panel. If you set the representation to Surface, you can then pick the color of the backface. You can do other things, to, such as turn on front face or back face culling, which you might find useful.

Re: [Paraview] Color surface by normal direction (inwards or outwards)
Lorenzo, Please don't forget to CC the list so that others may benefit from the discussion now and in the future through the list archives. As I mentioned in my previous email, using the Surface representation lets you pick the color. I just mentioned the culling options as potentially useful ways to see some things on your geometry. I didn't mean to lead you astray from your goal. Cory On Tue, May 29, 2012 at 11:28 AM, Lorenzo lovecraf...@gmail.com wrote: Thank you for your help Cory, that helps a lot. Anyway, I cannot select a color for the Cull FrontFace/BackFace options (see pic attached)… If I select one of each, the back/front face simply disappears and it comes back if I pan the stl the other way… that's quite confusing if you have a complex geometry… Now, I could load my geometry twice and enable backface for one and front face for the other and assign different colors for each model but I kind of hoped there was an easier way… Thank you! Lorenzo Il giorno 29/mag/2012, alle ore 17:16, Cory Quammen ha scritto: Lorenzo, Yes, you can do this. Under the Display tab, choose the color of the front face in the Color control panel. Set the Color by option to Solid Color, then pick the color you want with the Set Solid Color... button. Then scroll down almost to the bottom of the Display tab. There is a Backface Style panel. If you set the representation to Surface, you can then pick the color of the backface. You can do other things, to, such as turn on front face or back face culling, which you might find useful.

Re: [Paraview] CUDA module in ParaView
Hi John, Yes, I have a filter that uses cuda. I'm in progress of adding streaming capability to support larger datasets, and I'd have to roll back my current checkout to share with you which I haven't had time to do yet. My experience was similar to Dave's. It's very easy to use cuda from with PV, more challenging to use it well. I think you'll have no problem even without an example to work from.

Incidentally, I noticed Burlen had some CUDA related stuff in SQtoolkit that I found when googling. I will check that for hints.

Cc: paraview@paraview.org Subject: Re: [Paraview] CUDA module in ParaView Hey John, I've been working with LANL to get their PISTON library integrated into VTK and ParaView. It will be making its way into master over the next few weeks. Our work involves both GPGPU (data manipulation only) filters and a new direct from thrust to GL (glInterop) mapper. Getting vtk/paraview to use cuda wasn't too hard, just use CMake's FindCUDA module to get a hold of nvcc and then run that on the .cu files to get object files/symbols you can use from your VTK classes.

It doesn't actually have to be rendering as such as my current version just renders using software into a standard memory buffer and then copies that into OpenGL prior to letting paraview composite everything. It's mostly the setup/compilation etc that I haven't tried with CUDA and would like to experiment. thanks JB -- John Biddiscombe,email:biddisco @.at.@ cscs.ch http://www.cscs.ch/ CSCS, Swiss National Supercomputing Centre | Tel: +41 (91) 610.82.07 Via Trevano 131, 6900 Lugano, Switzerland | Fax: +41 (91) 610.82.82 ___ 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 ___ 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] node/element tracking
Hi Benjamin, if you are using the spreadsheet view you can select the interesting points and only show those ones. Once you play with time, you will see the coordinates of those points updating. If you were thinking of something else when you said tracking could you be more precise on what you had in mind ? Live text annotation / 3D lines...

When I load my .exo files position is not a history variable. If I make a selection of elements or nodes is there a way to track one of those single nodes or elements. I thought about using a line tool but the displacement is not 1D. There are two other files called a .lis and a .hiso which do track the x y z min and max displacements of the inserted blocks in my simulation but im looking for specific locations not just the min or max.

[Paraview] calculator
I know this should be very simple, but it certainly doesn't appear to be. I have to different sets of .vtk files each one representing different variables. All that I want to do is see the instantaneous correlation between the variables, i.e. I want to multiply them together. Unfortunately I can't figure out how to specify data from different files in the calculator. When I group the datasets, there is nothing that indicates what the name of the variables are...I'm guessing that would be helpful. -Jared CCS2/CNLS Postdoctoral Research Associate Los Alamos National Laboratory ___ 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] calculator
Take a look at this: http://paraview.org/Wiki/ParaView/Users_Guide/Python_Calculator#Comparing_Multiple_Datasets You can use similar approach to other arithmetic besides difference.
