Documentation

data Transform2 s Source

3D affine transform Instances Monoid (Transform2 s) (Fractional s, AdditiveGroup s) => Invertible (Transform2 s) (Floating s, Real s, MatrixComponent s) => Transform (Transform2 s) Geometry2

translate2 :: Num s => Vector2 s -> Transform2 s Source

Translation (motion) in 3D

rotate2 :: Num s => s -> Transform2 s Source

Rotation in 3D, with angle theta in radians.

scale2 :: Num s => s -> s -> Transform2 s Source

Scaling in 3D

uscale2 :: Num s => s -> Transform2 s Source

Uniform scale in 2D.

tweakMatrix2 :: (Floating s, MatrixComponent s) => Transform2 s -> IO () Source

Change the matrix state, according to the given transform.

tweakError2 :: (Real s, Fractional s) => Transform2 s -> ErrorBound -> ErrorBound Source

Change the required upper error bound, to one that applies before transforming. Hack for now.

toT3 :: Transform2 s -> Transform3 s Source
