Documentation

data Transform3 s Source

3D affine transform Constructors Identity3 Translate3 (Vector3 s) Rotate3 s (Vector3 s) angle (radians) and axis Scale3 s s s Compose3 (Transform3 s) (Transform3 s) Instances Eq s => Eq (Transform3 s) Show s => Show (Transform3 s) Monoid (Transform3 s) (Fractional s, AdditiveGroup s) => Invertible (Transform3 s) (Floating s, Real s, MatrixComponent s) => Transform (Transform3 s) Geometry3

translate3 :: Vector3 s -> Transform3 s Source

Translation (motion) in 3D

rotate3 :: s -> Vector3 s -> Transform3 s Source

Rotation in 3D, with angle in radians.

scale3 :: s -> s -> s -> Transform3 s Source

Scaling in 3D

uscale3 :: s -> Transform3 s Source

Uniform scale in 3D.

tweakMatrix3 :: (Floating s, MatrixComponent s) => Transform3 s -> IO () Source

Change the matrix state, according to the given transform.

tweakError3 :: (Real s, Fractional s) => Transform3 s -> ErrorBound -> ErrorBound Source

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