| http://www.w3.org/ns/prov#value | - The mapping from the 3D game world to your 2D television screen is called a projection; I won???t go too deeply into the maths just yet (and in fact in XNA, DirectX, OpenGL and other 3D SDKs, functions exist to perform much of the maths for you) but basically a projection transforms a 3D vector in world space to a 2D vector in screen space.
