When working with the graphics pipeline, the perspective projection is commonly used to give a realistic depiction of a scene, where objects close to the camera appear larger than objects far away. The perspective transformation has the important feature of mapping 3D lines to 3D lines. In this post we will go into why this property is important and give a proof of it.
The reader should have some familiarity with the graphics pipeline and the role the projection transformation plays in it. The Sources section provides good resources on the subject.
