Functions

func Max

func Max(a int, b int) int

Max returns the maximum value out of a and b.

func Min

func Min(a int, b int) int

Min returns the minimum value out of a and b.

func MinF

func MinF(a float32, b float32) float32

MaxF returns the maximum float value out of a and b.

Types

type AABB

type AABB struct {
	Min Vec // Min is the minimum extents of the bounding box.
	Max Vec // Max is the maximum extents of the bounding box.
}
