OpenGL and ControlP5
Feb 6th, 2009, 2:11pm  
Hi all,
i'm using ControlP5 AND OpenGL (pretty common i think).

I suspect this is a quite newbie question, so please be patient.

I'm implementing a zooming functionality by varying the fov parameter in the perspective() call.

The problem is that also the ControlP5 drawn GUI is zoomed in and out. I've also tried to disable the autodraw in ControlP5 but with no effect:

public void draw() {
background(255, 255, 255);

perspective();
controlP5.draw();

perspective(fov, aspect, cameraZ / 10.0f,
            cameraZ * 10.0f);
drawEllipses();
}

I just want a safe method to handle both ControlP5 GUI and OpenGL transformations.

Thank you in advance !

Rosario
