<p>The first 4 parameters define which area of the stage you want to view (the camera
will 'zoom' to exactly this region). The final 3 parameters determine the perspective
in which you're looking at the stage.</p>
<p>The stage is always on the rectangle that is spawned up between x- and y-axis (with
the given size). All objects that are exactly on that rectangle (z equals zero) will be
rendered in their true size, without any distortion.</p>

of the stage, with a field of view of 1.0 rad.</p>
