horizontalFieldOfView :: forall n. Lens' (PerspectiveLens n) (Angle n) Source #
verticalFieldOfView :: forall n. Lens' (PerspectiveLens n) (Angle n) Source #
orthoWidth :: forall n. Lens' (OrthoLens n) n Source #
orthoHeight :: forall n. Lens' (OrthoLens n) n Source #
facing_ZCamera :: (Floating n, Ord n, Typeable n, CameraLens l, Renderable (Camera l n) b) => l n -> QDiagram b V3 n Any Source #
'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 :: (Typeable n, Floating n, Ord n, Renderable (Camera PerspectiveLens n) b) => QDiagram b V3 n Any Source #
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 :: Floating n => PerspectiveLens n Source #
mm50 has the field of view of a 50mm lens on standard 35mm film, hence an aspect ratio of 3:2.
mm50Wide :: Floating n => PerspectiveLens n Source #
mm50blWide has the same vertical field of view as mm50, but an aspect ratio of 1.6, suitable for wide screen computer monitors.
mm50Narrow :: Floating n => PerspectiveLens n Source #
mm50Narrow has the same vertical field of view as mm50, but an aspect ratio of 4:3, for VGA and similar computer resolutions.
