[Paraview] Adding custom chart view
Hello, I'm trying yo create a filter to plot a histogram or a curve. The output of this filter will look like the one used for histogram filter. I read the documentation on the wiki about how to create a custom view, and I think this is my start point. Is that true ? if yes, from witch class should myView inherits from ? pqGenericViewModule ? pqChartLayer ? pqView ? pqxxx ? How my pqMyView class will be linked to my vtkMyFilter Class ? how to pass my vtkDataArrays from my vtkMyFilter class to my pqMyView class ? Thank you, Nehme ___ ParaView mailing list ParaView@paraview.org http://www.paraview.org/mailman/listinfo/paraview
Re: [Paraview] Adding custom chart view
Are you creating new new view for your filter, or do you want to simply show the output of the new filter in the current BarChart view used by the Histogram filter? If you are creating a totally new view, simply start by subclassing pqView. In the filter's XML you can use a hint as follows to indicate to ParaView which view to create by default for the filter. Hints !-- View can be used to specify the preferred view for the proxy -- View type=MyViewsXMLName / /Hints On Tue, Jan 13, 2009 at 10:16 AM, Nehme Bilal nbi...@mirarco.org wrote: Hello, I'm trying yo create a filter to plot a histogram or a curve.

Re: [Paraview] Adding custom chart view
Nehme,
It sounds like you do not need to create a custom view. You should be able to
create a filter that generates the data and then use the existing bar chart and
x-y plot views. You can specify a Hint in the server manager xml for a
filter to tell it which view to go to. See the implementation of
vtkPExtractHistogram and the corresponding ExtractHistogram entry in
filters.xml for more details.

Re: [Paraview] Difference between Compute Derivatives and Gradient (Unstructured)...
So its possible to change the gradient-filter to get a speedup? - nice.
Please let me know when this change is checked in into the cvs-version
of paraview - i will check it here again.
When I sent out my original email, I had already checked into CVS the
gradient filter optimization. This morning I checked in another change that
allows you to run a faster but less accurate algorithm to get the point
gradients.

[Paraview] Paraview multiple display
Hi everyone. I am trying to use paraview for side by side stereo display. I understand that I can link cameras between two display areas. The problem is that I don't know how to set a constant offset (like the distance between two eyes) of camera position for two linked cameras. Dose anybody have any idea? Thanks very much!

[Paraview] removing domain constraints
Hi, I am developing a helper class that do some prefiltering to remove constraints on the filters (need of point data instead of cell data for instance). It provides warnings when an interpolation is performed, but should allow to have all the filters available at any time. The pb I am now facing is that it seems that the constraints specified in the server xml are never removed in the inherited proxies. A typical usage is : vtkInterpolatedContour is a class that can take point or cell centered data and pre-interpolate it internally to point-centered data if needed. ServerManagerConfiguration ProxyGroup name=filters SourceProxy name=InterpolatedContour base_proxygroup=filters base_proxyname=Contour class=vtkInterpolatedContour label=InterpolatedContour InputProperty name=Input command=SetInputConnection ProxyGroupDomain name=groups Group name=sources/ Group name=filters/ /ProxyGroupDomain DataTypeDomain name=input_type DataType value=vtkDataSet/ /DataTypeDomain !-- I DISABLE THE ATTRIBUTE_TYPE HERE, BUT PARAVIEW STILL REQUIRES POINT CENTERED DATA -- !--InputArrayDomain name=input_array attribute_type=point number_of_components=1/-- /InputProperty /SourceProxy /ProxyGroup /ServerManagerConfiguration I can copy paste and modify the whole xml from the contour filter, but it seems to me that would be nicer to be able to use the base_proxy mechanism, any idea?

Re: [Paraview] removing domain constraints
Stephane, Unfortunately such more involved control for inheritance is not provided by ParaView, hence you'll have to go with copying the xml and changing it. The base_proxy mechanism is very simple (to say the least), it does not support overriding anything (including properties/domains) defined by the base _proxy.

[Paraview] paraview: uploading data files
Hi everybody! I am also new to this forum and new to paraview and python coding. I am currently looking to create an animation of shallow water waves using paraview, but I am having some trouble uploading my data files. At this stage, my data files are in excel files (.xls) and I am just wondering how I should go about converting them to paraview data files (.pvd) or the like, so that I may create an animation.

Re: [Paraview] Paraview multiple display
Hi Paraviewers. I guess that I didn't make my question clear in my last email. Here comes two specific questions: 1. I have tried camera link and property link separately to do my job. If I use camera link to link the camears in two views, after I rotate the camera in one view, the other camera will update itself automatically (The two views are exactly the same at all time). However, if I use property link, the other camera won't update itself unless I click on its view area (It needs focus to update). For property link, I only link two properties: CameraPosition and CameraViewUp. Is there a way that I can make the other camera update itself automatically? 2. I can't find any CameraRotation property, is there a way to link the rotation matrix of camera in different views? That means, the two different cameras in the two different views will multiply the same rotation matrix after a rotation. Thanks very much for your time!

Re: [Paraview] paraview: uploading data files
You will probably have to write some sort of custom reader for your data. This can be just a simple stand-alone program that converts your data into the .pvd file or you can make the reader a ParaView plugin so that ParaView can open your data file(s). The first thing you will probably want to do is export the data from excel into a CSV file for easier reading. Next you can write the code for your reader. If you can give some more information about what exactly the data in the xls files represents the community may be able to guide you further. For example is the data xyz coordinates for a triangular mesh? Is it voxel data? Is it image data? There are lots of examples for all of those around the net and from various folks on the list (including myself).
