Re: [Paraview] Widgets and RequestData
I have now figured out the problem, the unsigned long GetMTime() function needs to be overloaded to report a new modified time (this updated time is in the widget/vtkImplicitFunction). When the filter has a new modified time then RequestData gets called. This message written so that if anybody else ever has this problem they might have an easier time with it.

[Paraview] Segmentation fault in 3.11.1 when saving screenshot.
Hi All, I'm having some problems saving screen shots with the latest version of Paraview (3.11.1). This is compiled on an Ubuntu-64 bit system. Basically Paraview crashes with a segmentation fault every time I try to save a screen shot. The graphics card is admittedly low end, but this worked fine in 3.10. Has anyone else had this issue?

Re: [Paraview] Cosmo Reader - 64bit IDs
I will take a look at this tomorrow. I suspect it was hardcoded initially but I should be able to make that configurable pretty easily. David E DeMarle Kitware, Inc. RD Engineer 21 Corporate Drive Clifton Park, NY 12065-8662 Phone: 518-881-4909 On Wed, Aug 31, 2011 at 10:43 AM, joseph insley ins...@mcs.anl.gov wrote: Hi, I have some large data sets in the Cosmo format that I'd like to visualize with ParaView, but the format is slightly different from that expected by the built-in CosmoReader. Because the data sets I have use a very large number of particles, they use a 64bit int for the ID tag, rather than the 32bit expected by the reader. Looking at the source code for the reader (and HaloFinder) I see that there is an #ifdef ID_64, which if I understand correctly will compile the code using 64 bits for the particle IDs, just as I need. So my first question is, is this understanding correct? If so, how do I configure ParaView to build with the ID_64 defined? Is there some place that I need to add -DID_64 when running ccmake? Also, I assume this means that it will then only read datasets with the 64bit IDs. I do also have some data sets that use the standard 32bit ID format. I was hoping there would be a way (via the GUI perhaps) to specify the precision of the IDs, and use the same e xecutable, rather than maintain two builds of ParaView to accommodate the two cosmo formats. Any insight on any of this would be greatly appreciated.

[Paraview] Help getting resetting cameras between batch viz runs
I'm using the Python scripting facility in Paraview to do some batch visualization of some semiconductor models I'm simulating. The Start/Stop Trace feature is great, and I've already put together something quite usable. However, I can't figure out how to reset the camera between different simulations. The code coming out of the Trace feature looked something like: rv = pv.GetRenderView() rv.CameraFocalPoint = [0.223, -0.0160,-0.334] rv.CameraParallelScale = 1.684 rv.CenterOfRotation = [0.223, -0.0160,-0.334] rv.CameraPosition = [0.223, -0.0160, 4.105] rv.CameraClippingRange = [5.308, 8.033] i.e. they already got the center of the object from some query to the objects already in the database. What would I have to do to get this information myself? I'm having a hard time finding info. I've tried reading the doctext for the Outline and OutlineCorners features, and I've seen a couple refs to a GetBounds command while googling around, but I can't find anything that really helps. My pipeline looks something like: * Use the ExodusIIReader to create a reader object * Use the aforementioned render view object to control the camera * Create a slice object in the z-direction at a certain height * Create a data representation and a colormap * Render the object. I can't tell which of the objects I would use for an Outline() or a GetBounds() call. For example, I get the min/max values for the data in the slice via min,max = slice.PointData[0].GetRange() but using s or s.PointData with Outline() or GetBounds() doesn't get me anywhere. Can anyone nudge me in the right direction?

[Paraview] starting an animation before the first timestep
Hi, I am trying to make a nice animation with paraview. What I would like to do is add, for instance, an outline, a certain geometry and maybe other sources and then show the timevariant dataset. But adding those sources should be part of the animation. So, basically, I want to start the animation before the first timestep of the dataset. How can I do that? Thanks for any help!

[Paraview] visibility of the stream tracer
Hi, I have encountered two strange behaviors of ParaView both concerning the stream tracer. I wanted the streamlines to be seen only at certain time steps of my animation. So I used the Animation View to turn off the visibility at the beginning and then turn it on at a certain time step. Unfortunately the streamlines were visible in the entire animation. I had another problem with the stream tracer. I set the maximum length of a stream line to 6 (default was 17). When I turned off the visibility of the stream tracer by clicking on the eye and then turned it on again, ParaView ignored the maximum length of 6 and used 17 instead. Has anyone come across either of these problems?

Re: [Paraview] starting an animation before the first timestep
I can think of three ways. * Instead of save animation, use save screenshot. Then, manually create your images for the movie. * Same as above, but if you have any animations that need to be part of this, just write the animations down as individual images. * You could always use the Animation View, turning visibility of these sources and datasets on as time runs.
