Point or cell highlighting after picking it

[karelvrabeckv]

Hello,
I have implemented a point/cell picker (using vtkCellPicker). When a user picks a specific point/cell, some text information about it appears (e.g., id, position, etc.). It is a little bit user-unfriendly now because, after a while, I cannot remember which point/cell I have picked. Therefore, I have an idea to highlight the point/cell after the user clicks on it, and I am a bit struggling with it.

Now:

Intended:

Is it possible to implement this highlighting using Trame/VTK?
Are there any ideas or approaches on how to implement this?

Since I have access to a picked point/cell, I can change its properties, but I don't want to modify that data. Can it be implemented by (for example) creating copies of picked points/cells and coloring + rendering their edges only?

Thank you very much! :)

Yes, you should just create a new polydata>mapper>actor using the cell information. Then you set the line width bigger like on your render.
