Functions

func Box

func Box(
	targetMin, targetMax [2]float64, wrapX bool,
	itemDist func(min, max [2]float64, data interface{}) float64,
) (
	algo func(min, max [2]float64, data interface{}, item bool) (dist float64),
)

Box performs simple box-distance algorithm on rectangles. When wrapX is provided, the operation does a cylinder wrapping of the X value to allow for antimeridian calculations. When itemDist is provided (not nil), it becomes the caller's responsibility to return the box-distance.

func BoxDistCalc

func BoxDistCalc(aMin, aMax, bMin, bMax [2]float64, wrapX bool) float64

BoxDistCalc returns the distance from rectangle A to rectangle B. When wrapX is provided, the operation does a cylinder wrapping of the X value to allow for antimeridian calculations.
