Why an Atheist Thinks the Shroud of Turin is the Real Deal

Plotting in Space

Putting dot on a piece of paper is easy. Putting dots in space is more difficult. But leave it to artists, draftsmen and computer graphics people to figure out a way to do it. They do it by doing what a painter does and what a camera does. They create a three-dimensional representation of an object or a scene on a two dimensional surface.

That was a mouthful: a three-dimensional representation of an object or a scene on a two dimensional surface. And it needs to be said because there is a great deal of unnecessary confusion in the world about 2D and 3D foisted on us by elementary school teachers, philosophers, neuroscientists and computer graphics experts.

A square is a 2D object. A cube is a 3D object. A drawing of a square is a 2D picture. A drawing of a 3D object should be a 3D picture. But a 3D picture can also be a special picture that doesn’t look that good until you put on special glasses that give the illusion of depth in the same way that a 3D movie does. Of course a movie that you watch with special glasses is a 3D movie so all other movies are 2D movies even if they are motion pictures of 3D objects.
