In this chapter, we cover basic equations for rotating two-dimensional points and mapping them on the computer’s screen.

2.1 Rotation Equations

In this section, you learn the basic transformation equations to rotate points on a two-dimensional plane. You’ll begin by finding the equations that relate the coordinates of a point in a two-dimensional static coordinate system to a rotated one. The static coordinate ...
