Fields _orthoWidth :: Double Width _orthoHeight :: Double Height

Instances

Typeable * OrthoLens

horizontalFieldOfView :: Lens' PerspectiveLens Angle Source

verticalFieldOfView :: Lens' PerspectiveLens Angle Source

orthoWidth :: Lens' OrthoLens Double Source

orthoHeight :: Lens' OrthoLens Double Source

camLoc :: Camera l -> P3 Source

camForward :: Camera l -> Direction Source

camUp :: Camera l -> Direction Source

camRight :: Camera l -> Direction Source

camLens :: Camera l -> l Source

facing_ZCamera :: (CameraLens l, Backend b R3, Renderable (Camera l) b) => l -> Diagram b R3 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 :: (Backend b R3, Renderable (Camera PerspectiveLens) b) => Diagram b R3 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 :: PerspectiveLens Source

mm50 has the field of view of a 50mm lens on standard 35mm film, hence an aspect ratio of 3:2.

mm50Wide :: PerspectiveLens 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 :: PerspectiveLens Source

mm50Narrow has the same vertical field of view as mm50, but an aspect ratio of 4:3, for VGA and similar computer resulotions.

aspect :: CameraLens l => l -> Double Source

The natural aspect ratio of the projection.

camAspect :: CameraLens l => Camera l -> Double Source
