Graphics.GLUtil.Camera2D
Description
A camera designed for 2D viewing. The camera may be translated perpendicular to its view direction, or rolled about its view direction.
- data Camera a = Camera {
- forward :: V3 a
- upward :: V3 a
- rightward :: V3 a
- orientation :: Quaternion a
- location :: V3 a
- track :: (Conjugate a, Epsilon a, RealFloat a) => V2 a -> Camera a -> Camera a
- roll :: (Epsilon a, RealFloat a) => a -> Camera a -> Camera a
- rollRad :: (Epsilon a, RealFloat a) => a -> Camera a -> Camera a
- camera2D :: (Epsilon a, RealFloat a) => Camera a
- camMatrix :: (Conjugate a, Epsilon a, RealFloat a) => Camera a -> M33 a
- deg2rad :: RealFloat a => a -> a
Camera movement
A Camera may be translated and rotated to provide a coordinate
frame into which 3D points may be transformed.
track :: (Conjugate a, Epsilon a, RealFloat a) => V2 a -> Camera a -> Camera a Source
Move the camera side-to-side or up-and-down as in a tracking shot.
roll :: (Epsilon a, RealFloat a) => a -> Camera a -> Camera a Source
Roll a camera view about its view direction by an angle given in degrees.
rollRad :: (Epsilon a, RealFloat a) => a -> Camera a -> Camera a Source
Roll a camera view about its view direction by an angle given in radians.
