Constructor & Destructor Documentation

SMinMax() [1/2]

SMinMax

(

)

Default constructor.

SMinMax() [2/2]

SMinMax ( const Vector32 &  v )

explicit

Constructs with vector v set for both the minimum and maximum.

Parameters

[in]

v

The vector for minimum and maximum.

Member Function Documentation

Init() [1/2]

void Init

(

)

Resets the minimum and maximum to the largest values possible.

Init() [2/2]

void Init

(

const Vector32 &

v

)

Initializes the minimum and maximum with vector v.

Parameters

[in]

v

The value to initialize minimum and maximum.

AddPoint()

void AddPoint

(

const Vector32 &

p

)

Adds point p and recalculates the minimum and maximum.

Parameters

[in]

p

The point to add into the bounds.

AddPoints()

void AddPoints	(	const Vector32 &	a,
		const Vector32 &	b
	)

Adds points a and b and recalculates the minimum and maximum.

Parameters

[in]	a	The minimum point to add into the bounds.
[in]	b	The maximum point to add into the bounds.

Set()

void Set	(	const Vector32 &	a,
		const Vector32 &	b
	)

Sets the minimum and maximum of the bounding box.

Parameters

[in]	a	The minimum.
[in]	b	The maximum.

IsPopulated()

Bool IsPopulated

(

)

const

Checks if any points were added.

Returns

true if if any points were added to the bounds, otherwise false.

GetMin()

const Vector32& GetMin

(

)

const

Gets the minimum of the bounding box.

Returns

The minimum position of the bounds.

GetMax()

const Vector32& GetMax

(

)

const

Gets the maximum of the bounding box.

Returns

The maximum position of the bounds.

GetMp()

Vector32 GetMp

(

)

const

Gets the middle between the minimum and maximum (the center).

Returns

The center of the bounds.

GetRad()

Vector32 GetRad

(

)

const

Gets half the distance between the minimum and the maximum (the size).

Returns

The size of the bounds.

GetMpRad()

void GetMpRad	(	Vector32 *	mp,
		Vector32 *	rad
	)		const

Gets both the center and size of the bounding box.

Parameters

[out]	mp	Assigned the center of the bounds.
[out]	rad	Assigned the size of the bounds.
