[Paraview] Volume rendering for unstructured grids

Hello, i have a c++ servermanager application and i want to display a volume for given vtk file. I am using the vtkSMProxy classes. For the file reading i have the internal_sources,legacyreader proxy and for the volume representation i have the UnstructuredGridVolumeRepresentation. At this

[Paraview] writing a bunch of polyhedrons

Hi everyone, I have a list of polyhedrons which have arbitrary shape, and I would like to write them all down into a single .vtk file. I am using the POLYDATA data set. Right now, my option is: init global points init global faces for all polyhedra:    get local points    get local faces

Re: [Paraview] FW: FW: Coloured isosurfaces when running MPI

Hi Philipp, It seems you have hit a bug in the Contour filter occurring with 1 pvserver process and rectilinear grid input. I can reproduce the issue you reported as such: Load ParaView, connect to 1 pvserver processes Open Data/RectGrid2.vtk (e.g. from git://vtk.org/VTKData.git) Calculator

[Paraview] anti aliasing

Hello, I would like to use anti-aliasing on my scenes that I create in ParaView and output as image files. I have included 3D-models (.stl triangulated surfaces) in the scenes but they look rather poor in certain camera positions without anti-aliasing. I haven't found out how to activate this in

Re: [Paraview] anti aliasing

Hi, I don't know how to activate anti-aliasing directly in image file output process, but a way to achieve it is to render with an increase resolution (let's say double ligns and columns, i.e. x4 on pixel numbers) and after to externally resize the image files.

Re: [Paraview] python shell move data from client to server

Nope, moving data from client to server in the way you describe is not supported in ParaView. For what you are trying to do, you should really implement a filter (with multiple inputs, if needed) to do the data-manipulation on the server-side itself. Utkarsh On Wed, Jun 29, 2011 at 5:23 AM,

[Paraview] Merging Coincident Faces

I'm working with an Xdmf dataset in ParaView 3.10.1 that has multiple unstructured-grid blocks with overlap regions, however doens't seem to actually have ghost cells. This means when I extract an isosurface, I wind up with perfectly overlapping faces. I can use the Clean filter to eliminate

[Paraview] VTK File (PolyLines+Arrays) Crashes ParaView 3.10.1 when Rotated

Hello, I have generated a Legacy VTK file using VTK's Python wrapper. This file crashes ParaView 3.10.1 (Windows 7) when attempting to rotate it in ParaView's viewport, however, it seems that I can appropriately apply filters and such. However, this data did work properly on ParaView 3.8.1. If

Re: [Paraview] FW: FW: Coloured isosurfaces when running MPI

Thanks a lot for the help! Concerning the suggested workaround, I have a follow-up question: How would one get the Gouraud shading of the isocontours working? In my case I will get properly coloured isocontours, but they seem to have uniform shade for each triangle as opposed to an

[Paraview] How to Programatically add Items to drop down list?

Hi, I am writing a new vtk source and I need to programmatically populate a drop down list in the object-inspector/Properties from RequestInformation(). Are there any examples/code snippets that I could look at to help me do this? I defined the static drop down list this way so far, code

Re: [Paraview] python shell move data from client to server

If you use the python programmable filter, you can create it set the filter routine (python code) via a python macro on the GUI. If the data you are trying to manipulate on the GUI is small, you could encode it in a string and set it in the body of the python programmable filter. Pat On Wed,

Hi Pratik, I have had some similar issues when my desktop screen resolution was higher than the server display resolution. Do you know what the display resolution is set to on the server side? I was able to check the server side resolution using xrandr command. The issue was fixed by

Re: [Paraview] anti aliasing

For what it's worth, real-time anti-aliasing rendering has been turned off in ParaView because it wrecks havoc with many of the features involving rendering including picking, parallel rendering, transparency rendering, and tiled large image screen shots. Like Vincent suggested, if you need a

Hi all, I still have the same issue with 3.10.1 which I already had in 3.10.0: http://www.mail-archive.com/paraview@paraview.org/msg11218.html Am I the only one with such problems? I want to get this solved - what can I do? Shall I submit a bug? Regards Bastian

I think I have seen something like this. Make sure that a different version of qt isn't found earlier in your path or LD_LIBRARY_PATH. This includes installs of other applications... Hope that helps, Alan -Original Message- From: paraview-boun...@paraview.org

Re: [Paraview] Image Padding : extent problem again

Which filter is exhibiting this issue? One potential source for such behavior could be that the filter in question is not updating the WHOLE_EXTENT key in its RequestInformation implementation, and/or not updating UPDATE_EXTENT correctly in its REQUEST_DATA implementation. As a result ParView

Re: [Paraview] Merging Coincident Faces

The short answer is no. No such filter exists in ParaView or VTK. However, this can be done efficiently (no for loops within Python) if you have ParaView compiled with a Python that has NumPy. All official 3.10 binaries should have this. Here is the recipe: - Load data - Apply programmable

Re: [Paraview] Image Padding : extent problem again

I was informed that a feature will be added in the next release to at option correctly interpret extents at the price of potential additional IO. http://paraview.org/Bug/view.php?id=12298 Dominik On Wed, Jun 29, 2011 at 8:53 PM, Jérôme jerome.ve...@gmail.com wrote: Hi, A related thread can
