|enable||Enables (true) or disables (false) perspective projection|
This turns on (or off) perspective projection. With a
perspective projection instances that have a greater depth will
appear smaller, so when the depth is 0 it is equal to the original
size and the viewpoint for the camera is placed at a distance above
the room. This default distance is equal to the width of the room
as that gives a reasonable starting projection, and only instances
in front of the camera are drawn. Don't use instances with a depth
smaller than 0 (or at least not smaller than -w where w is the
width of the room or the view).
The above code switches on perspective projection.
