void core::aabox3d::addInternalBox

(

const aabox3d &

b

)

Adds an other bounding box to the bounding box, causing it to grow bigger, if the box is outside of the box

Parameters:

b,:	Other bounding box to add into this box.

References addInternalPoint(), MaxEdge, and MinEdge.

void core::aabox3d::addInternalPoint	(	f32	x,
		f32	y,
		f32	z
	)

Adds a point to the bounding box, causing it to grow bigger, if point is outside of the box.

Parameters:

x,:	X Coordinate of the point to add to this box.
y,:	Y Coordinate of the point to add to this box.
z,:	Z Coordinate of the point to add to this box.

References MaxEdge, MinEdge, core::vector3d::X, core::vector3d::Y, and core::vector3d::Z.

void core::aabox3d::addInternalPoint

(

const vector3d &

p

)

Adds a point to the bounding box, causing it to grow bigger, if point is outside of the box

Parameters:

p,:	Point to add into the box.

References addInternalPoint(), core::vector3d::X, core::vector3d::Y, and core::vector3d::Z.

vector3d core::aabox3d::getCenter

(

)

const

returns center of the bounding box

References MaxEdge, and MinEdge.

void core::aabox3d::getEdges

(

vector3d *

edges

)

const

stores all 8 edges of the box into a array

Parameters:

edges,:

Pointer to array of 8 edges

Edges are stored in this way: /1--------/3 / | / | / | / | 5---------7 | | 0- - -| -2 | / | / |/ | / 4---------6/

vector3d core::aabox3d::getExtent

(

)

const

returns extent of the box

References MaxEdge, and MinEdge.

bool core::aabox3d::isEmpty

(

)

const

returns if the box is empty, which means that there is no space within the min and the max edge.

void core::aabox3d::repair

(

)

repairs the box, if for example MinEdge and MaxEdge are swapped.

void core::aabox3d::reset	(	f32	x,
		f32	y,
		f32	z
	)

Resets the bounding box.
