structVec2 :: [Double] -> [Vec2]

Example: structVec2 [1,2,3,4] = [ Vec2 1 2 , Vec2 3 4 ].

destructVec2 :: [Vec2] -> [Double]

The opposite of structVec2.

det2 :: Vec2 -> Vec2 -> Double

vec2X :: Vec2

vec2Y :: Vec2

translate2X :: Double -> Vec2 -> Vec2

translate2Y :: Double -> Vec2 -> Vec2

sinCos :: Double -> Vec2

unit vector with given angle relative to the positive X axis (in the positive direction, that is, CCW). A more precise name would be cosSin, but that sounds bad :)

sinCos' :: Double -> Normal2

sinCosRadius

Arguments

:: Double

angle (in radians)

-> Double

radius

-> Vec2

angle2 :: Vec2 -> Double

The angle relative to the positive X axis

angle2' :: Normal2 -> Double

rotMatrix2 :: Double -> Mat2

Rotation matrix by a given angle (in radians), counterclockwise.

rotMatrixOrtho2 :: Double -> Ortho2

rotate2 :: Double -> Vec2 -> Vec2

rotateCCW :: Vec2 -> Vec2

Rotates counterclockwise by 90 degrees.

rotateCW :: Vec2 -> Vec2

Rotates clockwise by 90 degrees.
