Constructor & Destructor Documentation

BBox ( )

inline

The default constructor creates an invalid bounding box.

BBox	(	const Vec3T &	xyzMin,
		const Vec3T &	xyzMax
	)

inline

Construct a bounding box that exactly encloses the given minimum and maximum points.

BBox	(	const Vec3T &	xyzMin,
		const Vec3T &	xyzMax,
		bool	sorted
	)

inline

Construct a bounding box that exactly encloses the given minimum and maximum points.

If sorted is false, sort the points by their x, y and z components.

BBox	(	const Vec3T &	xyzMin,
		const ElementType &	length
	)

inline

Contruct a cubical bounding box from a minimum coordinate and an edge length.

Note: Inclusive for integral ElementTypes

BBox	(	const ElementType *	xyz,
		bool	sorted = `true`
	)

inlineexplicit

Construct a bounding box that exactly encloses two points, whose coordinates are given by an array of six values, x₁, y₁, z₁, x₂, y₂ and z₂.

If sorted is false, sort the points by their x, y and z components.
