Thank you for your answer,
given that it may be impossible to change the occluder of a WPF control, how can I design my own object defining the occluder? Can you give me an example? It will be fine enough for me 🙂
I would like to share the code with you, but since this is an university degree thesis, I’m still a bit hesitant about sharing the whole code publicly to the world. Maybe I can publish there on the forum only the part of the code (with comments) which is responsible for drawing the grid, or I can share the code of the whole project if you can give me an email where to send it.
Thank you again
