[Paraview] Adding time information to a .vts file
Hi, Is it possible to record time information of a simulation into a .vts file? I would like the time of the simulation to be displayed on the screen as I loop through my simulation. I have done this by writing a .pvd file, but just wondered if this can be recorded into a .vts file instead? I will be grateful if some one could give me a small example or point me towards some documentation.

[Paraview] Scaling Vector Arrow
Hi all, I want to visualize velocity fields with Glyph filter. We can apply scaling factor to Glyph filter. I'd like to fix shaft radius and tip size, and scale only shaft length with velocity magnitude. But if I apply scaling factor, both length and radius are scaled. Is there a way to do it?

Re: [Paraview] VTK XML Schema
I don't know of any documentation though it might exist for the XML schema. You may want to look at PyEVTK (https://bitbucket.org/pauloh/pyevtk) though as I've used that for structured grids (vtkImageData if I remember correctly) and it worked. It is supposed to support unstructured grids as well but I haven't tried that.

[Paraview] Plugin StringVectorProperty Array - string length display issue
Hi all, In a paraview plugin I am developing, I have a StringVectorProperty ArraySelection item in the GUI. The xml for this item is below. When the Get ArrayName function (GetFeatureFXArrayName) returns a char array of 26 characters or fewer, the display is fine. However, when the name is 27 chars or longer, it shows up blank in the selection window. Is there a way to increase the maximum name length (hopefully just an xml property). Thank you, Alex StringVectorProperty name=FeatureFXArrayInfo information_only=1 label=Feature Effects ArraySelectionInformationHelper attribute_name=FeatureFX/ /StringVectorProperty StringVectorProperty name=FeatureFXStatus command=SetFeatureFXStatus number_of_elements=1 repeat_command=1 immediate_update=1 number_of_elements_per_command=2 element_types=2 0 information_property=FeatureFXArrayInfo animateable=1 ArraySelectionDomain name=array_list RequiredProperties Property name=FeatureFXArrayInfo function=ArrayList/ /RequiredProperties /ArraySelectionDomain /StringVectorProperty ___ 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] trouble with Append Attributes
Hi all, I'm trying to display statistical values in color on a surface. The stat values are in voxels, originally, but are translated from a NIFTI format file to a .vtk format. I've got a binary version of the object (1's where the object is, 0's everywhere else). Through comments on this list, I've figured out that if I use the calculator to create a copy of the binary scalar values (and rename them as something else, e.g., surface), and then use Append Attributes to combine the stat data scalars with the surface scalars (from the binary image), I can then use Contour to make the surface (using the surface scalars) and then color this surface with the stat data scalars. So far so good. Here is my problem: When I do Append Attributes, the stat data scalars all get changed to a range of 0 to 1, even though the stat data file that was used in Append Attributes claims to have values of: [0, 128.619]. So, what is going on? Why is Append Attributes not appending attributes without changing their values?? Any ideas? -Tom _ P.

Re: [Paraview] trouble with Append Attributes
Sorry - scratch that. The Append Attributes item DOES claim to have the right values. According to the Information tab, there are 2 data arrays: One with scalars representing the stat data, and the other called surface which ranges from 0 to 1 and was created by the calculator step (see my last note). However, when I make a Contour out of this item, telling it to use surface to do this, it does indeed make a surface, but it inexplicably changes the stat data scalars to a completely new range of [127.863, 128.063]. Note that the Append Attributes item claims to have this same array with [0, 128.619]. Any ideas? As far as I can tell, Contour inexplicably changes the stat data scalar values to a new range. ??? Is this a bug, or am I doing something wrong? -Tom On Jun 27, 2012, at 10:36 PM, Tom Schoenemann wrote: Hi all, I'm trying to display statistical values in color on a surface.

Re: [Paraview] trouble with Append Attributes
I've narrowed it down a bit further. It appears that Contour inexplicably rescales ALL the data arrays, even though only one is used to create the surface. When I change the Isosurfaces data range (before applying the Contour) to different values (adding different values, adding ranges, etc.), this changes the range of the other data array after I apply. I don't want this other array touched. I'm not sure why this would be the default so I'm suspecting a bug?? Perhaps I'm missing something? In any case, is there actually a way to have Contour create a surface from one data array, but not fuss with the other data array (so that when I have the surface colored with this other array, the data don't get completely changed from real data to something else)? -Tom On Jun 27, 2012, at 10:50 PM, Tom Schoenemann wrote: Sorry - scratch that.
