bound

func (Bound) Center ¶

func (b Bound) Center() vec64.Vector

func (Bound) Cross ¶

func (b Bound) Cross(from, ray vec64.Vector, dist float64) (lmin, lmax float64, crosses bool)

Cross checks whether a given ray crosses the bound. from specifies a point where the ray starts. ray specifies the direction the ray is in. dist is the maximum distance that this method will check. Pass in math.Inf(1) to remove the check.

func (Bound) Grow ¶

func (b Bound) Grow(d float64) Bound

Grow increases the size of the bounding box by d on all sides. The center will remain the same.

func (Bound) HalfSize ¶

func (b Bound) HalfSize() [3]float64

func (Bound) Include ¶

func (b Bound) Include(p vec64.Vector) Bound

Include modifies the bounding box so that it contains the specified point.

func (Bound) Includes ¶

func (b Bound) Includes(p vec64.Vector) bool

Includes returns whether a given point is in the bounding box.

func (Bound) IsZero ¶

func (b Bound) IsZero() bool

IsZero returns whether the bound is the zero bound. This is not the same as being empty.

func (Bound) LargestAxis ¶

func (b Bound) LargestAxis() vecutil.Axis

func (Bound) Size ¶

func (b Bound) Size() [3]float64

func (Bound) String ¶

func (b Bound) String() string

func (Bound) Volume ¶

func (b Bound) Volume() float64

Volume calculates the volume of the bounding box
