structVec2 :: [a] -> [Vec2 a]Source
Example: structVec2 [1,2,3,4] = [ Vec2 1 2 , Vec2 3 4 ].
destructVec2 :: [Vec2 a] -> [a]Source
The opposite of structVec2.
translate2X :: Num a => a -> Vec2 a -> Vec2 aSource
translate2Y :: Num a => a -> Vec2 a -> Vec2 aSource
sinCos :: Floating a => a -> Vec2 aSource
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 :)
rotMatrix2 :: Floating a => a -> Mat2 aSource
Rotation matrix by a given angle (in radians), counterclockwise.
rotMatrixOrtho2 :: Floating a => a -> Ortho2 aSource
