[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?

Re: [Paraview] Help getting resetting cameras between batch viz runs
Marco, Thanks very much for your reply. Actually, it isn't the camera I need information on, it's the rest of the object. I need to know how big the thing I'm looking at is, so I can know where exactly I should move the camera. And I can't figure out how to get bounding box on any of the objects that are available to me. Do you have any idea?

Re: [Paraview] Help getting resetting cameras between batch viz runs
Thanks for the help people gave me for the question below. I now have a workable solution for much of the batch imaging I need to do. I'd now like to add some surface rendering, that is, setting >>> DataRepresentation.Representation = 'Surface' >>> DataRepresentation.ColorArrayName = 'solution' Previously, I had used the slice object to get the range of values and the bounds: >>> s = Slice(SliceType="Plane") >>> m,M = s.CellData[0].GetRange() >>> xmin,xmax,ymin,ymax,zmin,zmax = s.GetDataInformation().DataInformation.GetBounds() However, I no longer have the slice object. I have the DataRepresentation object, and the RenderView, and the output of the ExodusIIReader() call. I've also defined a number of elementblocks that I can set via: >>> reader.ElementBlocks = ['a','b'] Can I use any of the available objects to get the data and the boundary ranges? Thanks in advance...

[Paraview] WriteImage in the background
I'm currently doing some rendering on a large collection of exodus files using pvpython. I would like for this rendering to be done in the background. However, when I call WriteImage(filename), paraview pops up an X-window, and renders to the screen while saving the image. Is there any way to keep the window from showing up?
