Hi Paraview community,
In the file, I want to change the **AxisOfSymmetry** from 1 to 2, can anyone suggest an easy way to change it in Paraview? Thanks!
!!
vtkSuperquadricSource::vtkSuperquadricSource(int res)
{
res = res \< 4 ? 4 : res;
this-\>AxisOfSymmetry = 1; // y-axis symmetry
!!

You can do that by creating a very simple XML only plugin.

Thanks Mathieu! I have looked at the method you suggested. While it seems a little difficult for me to understand the code. Do you have any other example/document for me to learn how to write the plugin? I am using paraview 5.6, I hope to do it in the GUI.

Here you go :
- Save [SuperquadricAxisOfSymmetry.xml](https://discourse.paraview.org/uploads/short-url/fjmaVsXDRrj3J3N7Mgu3MntmQsc.xml) somewhere on your computer
- Open ParaView
- Tools -\> Manage Plugin -\> Load New -\> SuperquadricAxisOfSymmetry.xml
- Sources -\> Alphabetical -\> mySuperquadricSource

Thanks Mathieu for your help. I can successfully load the file your provided, while I could not see it. (I tested other examples, they can be seen.)
One more question, since I need to use TensorGlyph ( in TensorGlyph—\>select superquadric), how to make this change (AxisOfSymmetry=2) also works for TensorGlyph?

What do you mean ?

Once again, you need to do that in the xml plugin and point to your new superquadric source

I mean from **Alphabetical** , I can not find **mySuperquadricSource**. (I have tryed other examples, I can find them.).
Thanks again!
