data Camera l n Source

Instances

Num n => Transformable (Camera l n)
Typeable ((* -> ) -> -> *) Camera
Num n => Renderable (Camera l n) NullBackend
type V (Camera l n) = V3
type N (Camera l n) = n

data PerspectiveLens n Source

A perspective projection

Constructors

PerspectiveLens
Fields _horizontalFieldOfView :: Angle n Horizontal field of view. _verticalFieldOfView :: Angle n Vertical field of view.

Instances

Typeable (* -> *) PerspectiveLens
type V (PerspectiveLens n) = V3
type N (PerspectiveLens n) = n

data OrthoLens n Source

An orthographic projection

Constructors

OrthoLens
Fields _orthoWidth :: n Width _orthoHeight :: n Height

Instances

Typeable (* -> *) OrthoLens
type V (OrthoLens n) = V3
type N (OrthoLens n) = n

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

camLoc :: Camera l n -> Point V3 n Source

camForward :: Fractional n => Camera l n -> Direction V3 n Source

camUp :: Fractional n => Camera l n -> Direction V3 n Source

camRight :: Fractional n => Camera l n -> Direction V3 n Source

camLens :: Camera l n -> l 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.

aspect :: (CameraLens l, Floating n) => l n -> n Source

The natural aspect ratio of the projection.

camAspect :: (Floating n, CameraLens l) => Camera l n -> n Source
