Well it must be the rigth way but do not understand how to use it.
I do not find "clear" example. It is a picture to show what I want to do but
not example of code.
I have spend to much hours to try.
Thanks for all help.
Perhaps I will try later if I fnd more info.
I can not understand how to use photons and where?
