[Paraview] Spline Source and python script

[Ian Leslie]

Hi Jerome,
             Thanks for explaining in more detail. I tried the script but only two spline points were produced at 0,0,0 and 1,0,0.  No errors are given, so I can't point to a line in the code.  I am running ParaView 3.12.0, perhaps something changed between 3.10 and 3.12 to affect the script?  It is also possible I am overlooking something very obvious as I have only just started to use the python scripting in paraview.   This is the script I ran in the python shell  s = SplineSource() s.ParametricFunction.SetPropertyWithName( "Closed", 1 )  pointA = [1,2,3] pointB = [6,5,4] pointC = [7,8,9] s.ParametricFunction.SetPropertyWithName( "Points", pointA+pointB+pointC)  My goal is to have a python script that will take multiple point locations given in the script or from a file and produce a spline without having to manually enter them into the spline source one at a time.  Open to any suggestions and all ideas.   Thanks, 

Ian

    Hi,

    it is more a ParaView-related question, so I changed the list name
    ;)

    

    I tried again the solution Pat proposed in the post, and I am sorry
    to tell you that it works without changing anything...

    I just can be more precise. Please follow these steps in the
    paraview python shell :

    s = SplineSource()

    s.ParametricFunction.SetPropertyWithName( "Closed", 1 ) # Now, the
    "Closed Spline" property toggles to "checked"

    pointA = [1,2,3]

    pointB = [6,5,4]

    pointC = [7,8,9]

    s.ParametricFunction.SetPropertyWithName( "Points",
    pointA+pointB+pointC) # Now, the three points appear in the spline
    points list

    
    
    

    Then press apply : the spline appears in the render window.

    If you experience problems, please tell me which steps are guilty.

    

    HTH,

    Jerome

       Hi,

           I saw your post on getting the spline function to work in the
        pyhthon shell within ParaView on the vtk.org users mailing list
        and was wondering if you would be willing to share your solution
        with me.  I wasn't able to implement the suggested solution
        based on the post alone http://markmail.org/search/list:paraview?q=SplineSource+and+python+script#query:list%3Aparaview%20SplineSource%20and%20python%20script+page:1+mid:hhzkv5vj33zv6hky+state:results

         

        Thanks, 

        

        Ian
