Functions

func ConvertDirectionVectorToRadians

func ConvertDirectionVectorToRadians(vector Vector) float64

func GetDirectionDifference

func GetDirectionDifference(d1 float64, d2 float64) float64

GetDirectionDifference gets the difference between angels (in radians)

Important context: Radians range from 0 to 2PI

There should be a small difference between a value close to 2PI and a value close to 0 because if drawn on a circle they would be close.

Examples: 1PI - 1.5PI = 0.5PI, 1.75PI - 0.25PI = 0.5PI, 1.99PI - 0.01 = 0.02PI
