Documentation
rotateV :: Float -> Vector -> Vector Source #
Rotate a vector by an angle (in radians). +ve angle is counter-clockwise.
angleVV :: Vector -> Vector -> Float Source #
Compute the inner angle (in radians) between two vectors.
normalizeV :: Vector -> Vector Source #
Normalise a vector, so it has a magnitude of 1.
unitVectorAtAngle :: Float -> Vector Source #
Produce a unit vector at a given angle relative to the +ve x-axis. The provided angle is in radians.
