Detailed Description

A class for Axis-Aligned Bounding Box of a point set. It is used in an associated Kd tree class.

Constructor & Destructor Documentation

constructor for root AABB

Constructor for root gpAABB.

Parameters:

tree	pointer to the Kd tree, the AABB will belong to
inner_points	list of the points the AABB must bound

constructor for non root AABB

Constructor for non root gpAABB.

Parameters:

previous	pointer to the previous AABB in the tree
inner_points	list of the points the AABB must bound

int gpAABB::divide ( )

Divides an AABB along its larger dimension.

int gpAABB::draw ( unsigned int level )

Draws a gpAABB, as a wire box, if its level is equal to the input value or if it is a leaf.

Parameters:

level the value to compare to the gpAABB level

int gpAABB::sphereIntersection	(	p3d_vector3	center,
		double	radius,
		std::list< class gpContact > &	points
	)

Finds all the points belonging to the AABB that are inside a sphere.

Parameters:

center	sphere center
radius	sphere radius
points	points that are inside the sphere
