Collision of 3D objects in space

Cube Intersection

Design and start and application (or test project) which accepts as input dimensions and coordinates of two cubic objects (considering a 3D space). The application must determine whether the two objects collide and calculate the intersected volume. It's not a math exercise, so it is acceptable to consider the two cubes are parallel, so there is no rotation among themselves. The input coordinates define the center of the cube. The purpose of this exercise is to define the application design and architecture, focusing on the parts which ensure the correctness, performance and code clarity. Any design pattern is accepted and should be justified.

Object3D Abstract Class

It is an abstract class that defines the base structure of objects in space required for resolved this problem.

Properties	Type
Center	Vector3D
Type	Object3DTypes

Method	Parameters	Scope	Descriction
CollidesWith	thatObject	public	Returns if object collides or not with another object
IntersectedVolume	thatObject	public	Returns the intersection volume between objects. If objects not collide, then return value zero.
Volume		internal	Return the volume of object.

Cube Class

It is a derived class from Object3D and content the implementation for a cube object. In addition to the properties and methods inherited from Object3D, it also has the following defined:

Properties	Type
Dimensions	double
XAxis	Vector2D

Method	Parameters	Scope	Descriction
CollidesWithCube	thatObject	pprivate	Returns if cube object collides with other cube.
ResolveVolumeIntersectionWithCube	thatObject	private	Resolve an returns the intersection volume when cube object collised with other cube.

Coboid Class

It is a derived class from Object3D and content the implementation for a Coboid object. In addition to the properties and methods inherited from Object3D, it also has the following defined:

Properties	Type
Depth	double
Height	double
Width	double
