C# Class Axiom.Math.AxisAlignedBox

A 3D box aligned with the x/y/z axes.

This class represents a simple box which is aligned with the axes. It stores 2 points as the extremeties of the box, one which is the minima of all 3 axes, and the other which is the maxima of all 3 axes. This class is typically used for an axis-aligned bounding box (AABB) for collision and visibility determination.

Method	Description
AxisAlignedBox ( ) : System
AxisAlignedBox ( AxisAlignedBox box ) : System
AxisAlignedBox ( Vector3 min, Vector3 max ) : System
Clone ( ) : object
Contains ( Vector3 v ) : bool	Tests whether the given point contained by this box.
Equals ( object obj ) : bool
FromDimensions ( Vector3 center, Vector3 size ) : AxisAlignedBox	Return new bounding box from the supplied dimensions.
GetHashCode ( ) : int
Intersection ( AxisAlignedBox b2 ) : AxisAlignedBox	Calculate the area of intersection of this box and another

Intersects ( Plane plane ) : bool
Intersects ( Sphere sphere ) : bool	Tests whether this box intersects a sphere.
Intersects ( Vector3 vector ) : bool	Tests whether the vector point is within this box.
Merge ( AxisAlignedBox box ) : void	Allows for merging two boxes together (combining).
