Math for Transforming 3D Geometry

The positions of things in graphics are usually represented by vectors. The first number in a vector is called the x-coordinate and the second number is called the y-coordinate. Each number represents a dimension; a 3-dimensional vector has an additional coordinate called z.

Here are two different vectors, a and b. a’s x coordinate is 2 and its y coordinate is 3. Since these vectors have two numbers each, they represent positions in 2-dimensional space.
