Documentation

structVec2 :: [Float] -> [Vec2] Source

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

destructVec2 :: [Vec2] -> [Float] Source

The opposite of structVec2.

det2 :: Vec2 -> Vec2 -> Float Source

vec2X :: Vec2 Source

vec2Y :: Vec2 Source

translate2X :: Float -> Vec2 -> Vec2 Source

translate2Y :: Float -> Vec2 -> Vec2 Source

sinCos :: Float -> Vec2 Source

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' :: Float -> Normal2 Source

sinCosRadius Source

:: Float angle (in radians) -> Float radius -> Vec2

angle2 :: Vec2 -> Float Source

The angle relative to the positive X axis

angle2' :: Normal2 -> Float Source

rotMatrix2 :: Float -> Mat2 Source

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

rotMatrixOrtho2 :: Float -> Ortho2 Source

rotate2 :: Float -> Vec2 -> Vec2 Source

rotateCCW :: Vec2 -> Vec2 Source

Rotates counterclockwise by 90 degrees.

rotateCW :: Vec2 -> Vec2 Source

Rotates clockwise by 90 degrees.
