Detailed Description

A class for Axis-Aligned Bounding Box of a p3d_polyhedre (a set of triangles). It is used in an associated Kd tree class.

Constructor & Destructor Documentation

constructor for root AABB

Constructor for root gpAABBTris.

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 gpAABBTris.

Parameters:

previous	pointer to the previous AABB in the tree
xmin	minimal coordinate of the AABB along x axis
xmax	maximal coordinate of the AABB along x axis
ymin	minimal coordinate of the AABB along y axis
ymax	maximal coordinate of the AABB along y axis
zmin	minimal coordinate of the AABB along z axis
zmax	maximal coordinate of the AABB along z axis
inner_points	list of the points the AABB must bound

int gpAABBTris::divide ( )

Divides an AABB along its larger dimension.

int gpAABBTris::draw ( unsigned int level )

Draws a gpAABBTris if its level is equal to the input value or if it is a leaf and if it is not ouside the polyhedron interior.

Parameters:

level the value to compare to the gpAABB level

bool gpAABBTris::isInsidePolyhedre ( )

Tests if the AABB is entirely inside the p3d_polyhedre.

Returns:: true if the AABB is completely inside the triangle mesh, false otherwise

bool gpAABBTris::isTriangleOutside	(	p3d_vector3	p1,
		p3d_vector3	p2,
		p3d_vector3	p3
	)

Tests if a triangle is completely outside the AABB.

Parameters:

p1	first vertex of the triangle
p2	second vertex of the triangle
p3	third vertex of the triangle

Returns:: true if the triangle is completely outside the AABB, false otherwise
