The language allows me to define focal blur on an orthographic projection but
the results i'm getting are meaningless images of the scene blurred out of
existence (I used lots of aperture values and they where all this way). I know
focal blur doesn't make physical sense for orthographic projection. I would
define focal blur here as each ray is parallel except for a bit of a random
angle. I'm trying to simulate rays from the sun. (Like a blurred out image from
the perspective of the sun.) Has anyone gotten focal blur to produce something
good in orthographic, otherwise could I define my own camera to do this?
