[Paraview] vtkUniformGrid
Hi I'm writing a filter which creates a vtkUniformGrid as its output. The grid is setup is done using the following code: vtkUniformGrid *grid = vtkUnformGrid::SafeDownCast(outInfo->Get(vtkDataObject::DATA_OBJECT)); grid->Initialize(); grid->SetOrigin(origin.data()); grid->SetDimensions(bins.data()); grid->GetDimensions(); // Call this so the dimensions array is set - stupid VTK grid->SetNumberOfScalarComponents(3); grid->SetScalarTypeToDouble(); grid->SetSpacing(spacing.data()); grid->AllocateScalars(); I checked that spacing, origin and bins are set correctly. Yet, when I run this filter (without setting any data, that data will therefore be noise), I get an output in paraview without Extent, without an Origin and without a bounding box, 0 cells etc. What am I doing wrong here? ___ 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
[Paraview] Disabling auto-drawing in ParaView
Hi, Is it possible to disable auto-drawing of data in ParaView after a filter is applied? For example, I'd like to apply 3 filters, one after the other, but I only want to see the result presented in the render window after the last one has been applied. At the moment, after each filter is run, it auto-redraws it on screen and can get a bit annoying.

Re: [Paraview] vtkUniformGrid
Hi John
To compute this information, I need the whole bounding box of the
incoming object. I assume it's not saved in WHOLE_EXTENT as it seems
integer based. Which key stores that info so I can output it in my reader?
Thanks - I tried these keys in the request_data function and it did have
some effect (I obviously need to do it earlier...)

Re: [Paraview] Disabling auto-drawing in ParaView
Hey Adriano, I don't think ParaView is built to do this, although I can see where it would be a very useful feature for some applications (I think this is the standard behavior in LLNL's VisIt). As a workaround, if your three filters are always the same you can combine them into a Custom Filter, exposing the parameters you need to adjust each time. This allows you to set up the pipeline for all three filters (inside the custom filter black box) and only update when you hit Apply at the end. -Eric -- Eric E Monson Duke Visualization Technology Group On Nov 25, 2009, at 6:15 AM, Adriano Gagliardi wrote: Hi, Is it possible to disable auto-drawing of data in ParaView after a filter is applied?

[Paraview] Integrate Variables + Boxes

I also had some fun in positioning an ExtractMeshByRegion Box using Tranlation/Rotation/Scale. Especially translation is unclear to me how it works. Why does in not use the Center and length convention from the Box-source? I used a box-source to position my extraction.

[Paraview] rotating and shifting image data
Hi, I'm working on a python script to open MRI images in NIFTI format in paraview. I'm using "simple.ImageReader" to read the volume data. However, the file header specifies a 4x4 matrix which transforms voxel indices to coordinates in a reference coordinate system in mm, and I would like to use the mm coordinates in paraview. There is a VTK thread on doing this (http://old.nabble.com/world-coordinates-and-image-data-td22217332.html) and the solution was to use "vtkImageReslice" together with a transform using "vtkMatrix4x4". However, the "vtkImageReslice" filter does not seem to be present in the VTK version that comes with ParaView (3.6.1-r1 on Gentoo). (Apart from this I couldn't figure out how to use VTK filters on "simple.ImageReader"). Since this didn't work, I tried a different method. The 4x4 matrix in the file is usually purely rotational and translational, I can extract the rotation and translation parameters for each dimension from the matrix and then simply rotate and shift the Image object. This can be done in Python using ... simple.Show(img) props = simple.GetDisplayProperties(img) props.Orientation = (180*alpha/pi, 180*beta/pi, 180*gamma/pi) props.Position = (tx, ty, tz) ... Where img is the "simple.ImageReader" object. This does rotate and translate the volume (image). However, the problem is that if apply a filter on it (e.g. Slice) the output of the filter is not shifted and translated, and thus does not appear at the same location as the image. I also tried using "simple.Transform" for the rotation and translation, but it looks like it doesn't support Image objects as input. Any hints on how to do this are greatly appreciated.

There is a few issues on Gentoo may be you should file a bug. Actually speaking of bugs can you take a screenshot? I cannot I get "failed to create pixmap" and then a segfault. I cannot quite figure what's wrong apart may be a bug in my openGL drivers.

[Paraview] Recent Xdmf volume rendering
Hey all, I just noticed today that I can't volume render my Xdmf ImageData sets in CVS ParaView (today's -- OS X 10.5.8, serial build, Qt 4.5.2 cocoa, cmake 2.9.20091003). With the binary PV 3.6.1 I can load in a temporal collection or single 3DCoRectMesh and it volume renders fine. With current 3.7 (now using vtkXdmfReader2, I assume), this data shows up as "Image (Uniform Rectilinear Grid) with blanking" and I can choose volume rendering but nothing shows up in the render window. Volume rendering of a Wavelet Source works just fine, so I'm wondering what the "with blanking" part is, and if that's what's causing my trouble?

About the screenshot, this seems to have something to do with you graphics driver. For me, it only work with ati-drivers (Radeon HD4830), it does not work with xf86-video-intel (Intel X3100) and xf86-video-radeonhd (ATI X1300). It seems to have something to do with this bug: http://bugs.gentoo.org/show_bug.cgi?id=279060 I'm getting the "GL_VERSION_1_4_DEPRECATED" on the systems where it doesn't work. -- __ Martin Luessi, M.S.

Re: [Paraview] rotating and shifting image data
Ok, I found the vtkImageReslice filter: from paraview.vtk.imaging import vtkImageReslice I didn't realize that it was "hidden" in the imaging module. This brings me back to the question on how to use vtkImageReslice with the simple.ImageReader object. Is this possible, or do I have to use the vtkImageReader instead? best, Martin -- __ Martin Luessi, M.S.

Re: [Paraview] Off Screen Rendering
Dear all, so based on the timer log results that i collected, what i read about offscreen-rendering and the explanation below, can i conclude the followings? someone pls correct me if i'm wrong! with --use-offscreen-rendering X windows are disabled on all server processes all server processes render the geometry locally then each server processes sends the image to the client for compositing there's NO data gathering to process 0, meaning the master doesn't collect all images from each processes for composting, then only send it to the client for rendering that's why --use-offscreen-rendering is faster without --use-offscreen-rendering X windows are enabled on all server processes all server processes the raw data, then send all geometry to process 0 process 0 gather all geometry then send them to the client to render the client does all the rendering job that's why without --use-offscreen-rendering is slower any help / reply is highly appreciated Best Regards, chewping Date: Fri, 20 Nov 2009 10:57:25 +0800 From: weaponfire2...@163.com To: lcp8...@msn.com CC: paraview@paraview.org Subject: Re:[Paraview] Off Screen Rendering hi chew ping： The Problem:"Display is not accessible on the server side. Remote rendering will be disabled.", it means that not all server start up X Server, so the server will process the raw data and send all geometry to the client to render. The client do all the rendering job, that's the reason why case 2 is so slow, I think. When you use off screen, all server processes render the geometry locally , send image to client to composite, so case 1 much faster than case 2. I hope this can help you, for I got the same problem before. Good luck. 在2009-11-20，"chew ping" 写道： Dear all, i'm doing parallel rendering using 2 machines (np4), i notice an obvious difference between using offscreen-rendering (faster) and without offscreen-rendering (much slower). i realize this from the timer log: Case 1: with offscreen-rendering -- Local Process Still Render, 0.666444 seconds Execute vtkMPIMoveData id: 519, 0.000199 seconds Execute vtkPolyDataMapper id: 311, 0.000106 seconds Server, Process 0 Execute vtkFileSeriesReader id: 238, 0.645881 seconds Execute vtkPVGeometryFilter id: 305, 0.005891 seconds Execute vtkPVCacheKeeper id: 516, 7.8e-05 seconds Execute vtkMPIMoveData id: 519, 0.000212 seconds Execute vtkOrderedCompositeDistributor , 0.000152 seconds Execute vtkPolyDataMapper id: 311, 0.000274 seconds Server, Process 1 Execute vtkFileSeriesReader id: 238, 0.000275 seconds Execute vtkPVGeometryFilter id: 305, 0.005299 seconds Execute vtkPVCacheKeeper id: 516, 7.7e-05 seconds Execute vtkMPIMoveData id: 519, 0.000147 seconds Execute vtkOrderedCompositeDistributor , 0.000117 seconds Execute vtkPolyDataMapper id: 311, 9.9e-05 seconds Server, Process 2 Execute vtkFileSeriesReader id: 238, 0.000258 seconds Execute vtkPVGeometryFilter id: 305, 0.004765 seconds Execute vtkPVCacheKeeper id: 516, 7.7e-05 seconds Execute vtkMPIMoveData id: 519, 0.000147 seconds Execute vtkOrderedCompositeDistributor , 0.000111 seconds Execute vtkPolyDataMapper id: 311, 9.5e-05 seconds Server, Process 3 Execute vtkFileSeriesReader id: 238, 0.000352 seconds Execute vtkPVGeometryFilter id: 305, 0.005351 seconds Execute vtkPVCacheKeeper id: 516, 7.7e-05 seconds Execute vtkMPIMoveData id: 519, 0.000168 seconds Execute vtkOrderedCompositeDistributor , 0.000111 seconds Execute vtkPolyDataMapper id: 311, 0.000108 seconds --- Case 2: without offscreen-rendering --- Local Process Still Render, 4.86495 seconds Execute vtkMPIMoveData id: 520, 2.81566 seconds Execute vtkPolyDataMapper id: 312, 0.00012 seconds Execute vtkPolyDataMapper id: 148, 7.6e-05 seconds Server, Process 0 Execute vtkFileSeriesReader id: 239, 0.659133 seconds Execute vtkPVGeometryFilter id: 306, 0.026125 seconds Execute vtkPVCacheKeeper id: 517, 7.8e-05 seconds Execute vtkMPIMoveData id: 520, 2.53214 seconds Dataserver gathering to 0, 1.98166 seconds Dataserver sending to client, 0.549715 seconds Execute vtkOrderedCompositeDistributor , 0.000175 seconds Server, Process 1 Execute vtkFileSeriesReader id: 239, 0.000446 seconds Execute vtkPVGeometryFilter id: 306, 0.026313 seconds Execute vtkPVCacheKeeper id: 517, 7.3e-05 seconds Execute vtkMPIMoveData id: 520, 0.232435 seconds Dataserver gathering to 0, 0.232117 seconds Execute vtkOrderedCompositeDistributor , 0.00012 seconds Server, Process 2 Execute vtkFileSeriesReader id: 239, 0.000519 seconds Execute vtkPVGeometryFilter id: 306, 0.026063 seconds Execute vtkPVCacheKeeper id: 517, 7e-05 seconds Execute vtkMPIMoveData id: 520, 1.31373 seconds Dataserver gathering to 0, 1.31341 seconds Execute vtkOrderedCompositeDistributor , 0.000119 seconds Se
