Re: [Paraview] pvpython WriteImage output corrupted

Re: [Paraview] pvpython WriteImage output corrupted
I have tried setting the view.UseOffscreenRendringForScreenshots to 0 with no luck. Still the same corrupted image output. And I am making a series of images in a loop also. I am updating the same view, however, not deleting and recreating a new one. I wonder if that would work. Also, in the last few days I've built paraview from source with OSMesa support and tried using offscreen rendering, but that results in a seg fault at Render(). I must not have it set up properly.

Re: [Paraview] Opening xyz file /DEM in Paraview
If you actually have data in DEM format ( http://en.wikipedia.org/wiki/USGS_DEM), you can open it in ParaView by simply adding a .dem extension to the file. I am not sure if this is the case though. .xyz is a pretty common extension so it is hard for us to help without knowing specifics. If you load in a set of points with csv reader, you can use one of the Delaunay filters to mesh them.

Re: [Paraview] pvpython WriteImage output corrupted
Today I reinstalled a local version of OSMesa (7.8.2) and rebuilt ParaView pointing to this new installation of OSMesa, and the rendering output using on-screen rendering (X) from WriteImage now works! There must have been a conflict with versions of GL files (?) that was causing corrupted output. On the other hand, when I try to use off-screen rendering, the script still bombs, but has the error: pvbatch: main/renderbuffer.c:1924: _mesa_add_renderbuffer: Assertion 'bufferName == BUFFER_DEPTH || bufferName == BUFFER_STENCIL || fb-Attachment[bufferName].Renderbuffer == ((void *)0)' failed. This is an improvement that I can get some WriteImage() output to save properly now, but I would in the end like to be able to get off-screen rendering to work in order to run the script in a non X environment.

[Paraview] Packaging ParaView
Hi, I'm trying to package ParaView with our build options, but it looks like the CPackParaViewConfig.cmake file is no longer available in 3.98.1, unless I missed a CMake variable. I've been looking at two ways to handle this: superbuild and rebranding. I really don't need to rebrand ParaView, as we aren't wrapping in any new functionality. So, I was thinking of going with the superbuild. Can the superbuild be made to only package ParaView provided libraries and plugins? Our analysis package which uses ParaView functionality already provides many of the same dependencies (Qt, HDF) and we build ParaView against these. Therefore, we don't need to duplicate them in the installation package.

[Paraview] How to display the cellNormals as vectors?
Hi all, I have just imported a 3D parametric surface in Paraview (from a .VTU file generated by a Python script), and I'm wondering how to display the cellNormals as actual vectors. Since a cellNormal has an X, Y and Z component, it should be possible to use these three scalar values to create a vector, pointing from the corresponding cell. I know I can create a vector field with the Glyph function, but I'm not sure how to continue from there. I cannot select any Scalars or Vectors from the two dropdown menus/lists (they are enabled but there is nothing to select). Any ideas on how to proceed would be very welcome!

Re: [Paraview] How to display the cellNormals as vectors?
Does the file actually contain normals? I am guessing not. In that case, do: Extract Surface Generate Surface Normals Glyph If you had a vtp file (polydata) instead of vtu (unstructured grid), you wouldn't need to Extract Surface. -berk On Mon, Apr 15, 2013 at 7:27 PM, Pieter Barendrecht pie...@redpanda.nlwrote: Hi all, I have just imported a 3D parametric surface in Paraview (from a .VTU file generated by a Python script), and I'm wondering how to display the cellNormals as actual vectors.

Re: [Paraview] How to display the cellNormals as vectors?
ParaView does a weird thing, in the Color By drop down menu, it show an array named cellNormals but this array doesn't actually exist on the data object, and it doesn't appear in the information tab. So, as Berk said, you should apply the Generate Surface Normals filter, and make sure you check the Compute Cell Normals check box. Then you can use the Cell Centers to generate point data at the cell centers. Then you can use the Glyph filter to draw the arrows for the cell normals.

Re: [Paraview] writing volume to stl as topology
Hi Dmitry, I have a tetrahedral mesh in vtk unstructured grid. How can I write this volume to stl (not just the surface) like a set of separated triangles? Paraview display my data as a surface. Here is some screenshots of my model and clipped model. My goal is just to handle this topology and then print it by 3D printer. The STL format only accepts triangles, not tetrahedra or other volumetric elements. Your 3D printer software will infer what regions are inside and outside the surface as long as the surface is manifold (i.e., a closed, orientable surface that is watertight). If you have a model that is not watertight, you can try using ParaView's Clean filter to fix it.
