most of you maybe already know my problem, and it's still the same..

I want to program a program with 3 "frames". one on the top of the program where buttons are placed (controlP5?). one on the left, where a textfield is placed.. Automatically there is placed some text and when you click on a word a popup is opened.. and a third frame in the middle.. this frame has to be in 3d with a coordinate system that I can translate and rotate and so on..

everything of this I've already programmed. but it's difficult to combine this things. I don't know how. And I think I should change the way I've programed the coordinate system--> I should travel with matrixes, or not? In this 3d area I want to draw things that I can rotate.. I should be able to read the x,y-position of the mouse and also the z (that's also possible when I project the window, or not?) but for this, it's much easier to work with a matrix!? So how does this work in processing?

has anybody programmed something like that? does anybody know how to do it? I'm very happy about every answer.. because I'm stuck..

thank you..

thank you very much.. I'll have a look on it. (at the moment time is missing   )

other ideas? the more I have the better it is..

will study them as soon the time's here
