Functions

func Lerp

func Lerp[T constraints.Integer | constraints.Float](a, b T, ratio float64) T

Linearly interpolate between any two numbers of the same type using a ratio. The ratio is capped between 0 and 1

func LerpColor

func LerpColor(a, b color.RGBA, ratio float64) color.RGBA

Creates a color between the given a and b. 0 means a is given, 1 means b is given, .5 is a color half way between. The ratio is capped between 0 and 1 Currently the function floors the number instead of rounding to nearest.
