Functions ¶

func Contains ¶ added in v0.13.0

func Contains(r R, s R) bool

Contains checks if the input rectangle r fully encloses s. r is a closed interval.

func Disjoint ¶ added in v0.13.0

func Disjoint(r R, s R) bool

func SA ¶ added in v0.11.0

func SA(r R) float64

SA returns the "surface area" of an N-dimensional interval. For N = 2, this is the perimeter, and for N = 3, this is the total surface area of the rectangular prism.

See https://math.stackexchange.com/a/1898563 for the full method.

func V ¶ added in v0.11.0

func V(r R) float64

func Within ¶ added in v0.12.0

func Within(g R, h R) bool

func WithinEpsilon ¶ added in v0.12.0

func WithinEpsilon(g R, h R, e epsilon.E) bool

Types ¶

type M ¶ added in v0.13.0

type M R

func (M) Copy ¶ added in v0.13.0

func (r M) Copy(s R)

func (M) Intersect ¶ added in v0.13.0

func (r M) Intersect(s R) bool

func (M) Max ¶ added in v0.13.0

func (r M) Max() vector.M

func (M) Min ¶ added in v0.13.0

func (r M) Min() vector.M

func (M) R ¶ added in v0.13.0

func (r M) R() R

func (M) Scale ¶ added in v0.14.0

func (r M) Scale(c float64)

Scale will expand or shrink each dimension of the AABB by the given scalar.

If we want to expand or shrink by the total volume instead, we can use

b.Scale(math.Pow(c, 1.0 / b.Min().Dimension()))

func (M) Union ¶ added in v0.13.0

func (r M) Union(s R)

func (M) Zero ¶ added in v0.13.0

func (r M) Zero()

type R ¶

type R struct {
	// contains filtered or unexported fields
}

func Intersect ¶ added in v0.13.0

func Intersect(r R, s R) (R, bool)

func New ¶

func New(min vector.V, max vector.V) *R

func Scale ¶ added in v0.14.0

func Scale(r R, c float64) R

func Union ¶ added in v0.13.0

func Union(r R, s R) R

func (R) D ¶

func (r R) D() vector.V

func (R) In ¶

func (r R) In(v vector.V) bool

func (R) M ¶ added in v0.13.0

func (r R) M() M

func (R) Max ¶

func (r R) Max() vector.V

func (R) Min ¶

func (r R) Min() vector.V
