We've decided to step into a virtually real world. To understand how to draw that world, we'll need to understand exactly how to describe it.
This chapter describes how we do that in a mathematical sense. Don't worry, this is not a return to high–school math! (Well, maybe geometry. OK, so maybe a little bit. OK, maybe a lot. I'll try to make it painless.)
There are many different ways to describe the world; it is still the same world no matter how we do so. As Shakespeare said in Romeo and Juliet:
"What's in a name? That which we call a rose by any other name would smell as sweet."
