Graphics.FieldTrip.Vector2 Stability experimental Maintainer conal@conal.net, andygill@ku.edu

Description

Vectors in 2D. Uses the OpenGL Vector2 type, for convenience and efficiency.

Synopsis

vector2y :: Vector2 s -> s xVector2 :: Num s => Vector2 s yVector2 :: Num s => Vector2 s vector2Polar :: Floating s => s -> s -> Vector2 s vector2PolarCoords :: (InnerSpace s s, Floating s) => Vector2 s -> (s, s) vector2D :: (HasBasis a s, HasTrie (Basis a), VectorSpace s s) => Two (a :> s) -> a :> Vector2 s unvector2D :: (HasBasis a s, HasTrie (Basis a), VectorSpace s s) => (a :> Vector2 s) -> Two (a :> s)

Documentation

vector2y :: Vector2 s -> s Source

xVector2 :: Num s => Vector2 s Source

The unit vector in the positive X direction.

yVector2 :: Num s => Vector2 s Source

The unit vector in the positive Y direction.

vector2Polar :: Floating s => s -> s -> Vector2 s Source

Vector from polar coordinates. See also vector2PolarCoords.

vector2PolarCoords :: (InnerSpace s s, Floating s) => Vector2 s -> (s, s) Source

Polar coordinates of a vector. See also vector2Polar.
