Keep square proportion of a quad in fullscreen mode

Hi how are you? It’s me again ;) trying to understand VVVV a little more everyday.

I have a perfectly square quad on my renderer. But in fullscreen my quad is no more a square, because it “copy” the screen proportions. I would like being in fullscreen mode, but having a square in it, (independently of the screen resolution).

Of course this is a simplified representation of my problem, in my real case I have a lot of things on the screen, but for understanding purposes works the same ;)

Thank you very much.

please read dx9 rendering for understanding the issue. then check the helppatch of Renderer (EX9) and see how it uses AspectRatio (Transform).

Thank you very much for the links joreg!

I’ll read the docs…
