camForward :: Direction d => Camera l -> dSource
facing_ZCamera :: (CameraLens l, Backend b R3, Renderable (Camera l) b) => l -> Diagram b R3Source
'facing_ZCamera l' is a camera at the origin facing along the negative Z axis, with its up-axis coincident with the positive Y axis, with the projection defined by l.
mm50Camera :: (Backend b R3, Renderable (Camera PerspectiveLens) b) => Diagram b R3Source
A camera at the origin facing along the negative Z axis, with its up-axis coincident with the positive Y axis. The field of view is chosen to match a 50mm camera on 35mm film. Note that Cameras take up no space in the Diagram.
mm50 has the field of view of a 50mm lens on standard 35mm film, hence an aspect ratio of 3:2.
mm50Wide :: PerspectiveLensSource
mm50blWide has the same vertical field of view as mm50, but an aspect ratio of 1.6, suitable for wide screen computer monitors.
mm50Narrow :: PerspectiveLensSource
mm50Narrow has the same vertical field of view as mm50, but an aspect ratio of 4:3, for VGA and similar computer resulotions.
