i'm guessing it's using atan2

http://en.wikipedia.org/wiki/Atan2

look at the diagram at the very bottom, on the left, and you'll see a jump where one of the values crosses HALF_PI

(1.57 = HALF_PI)

Thanks koogy. Do you think one can grab these values and pass them to the buffer to rotate an object
Something with map(value, min, max, newmin, newmax)

Solved!
With the latest version of PeasyCam, mr Feinberg added a new method for CameraState:
apply(processing.core.PGraphics g)

So to render 'on demand' with the SAME angles you see in the display window, that's all you need to do:

case 's':
noLoop();  
recorder = createGraphics(width, height, "hipstersinc.P5Sunflow");
recorder.beginDraw();
cam.getState().apply(recorder); // apply the latest CameraState
scale(30.0); // a scale factor is needed
draw();
recorder.endDraw();
recorder.save((int) random(10000)+".png");
recorder = null;
loop();
break;
