Summary

By now, I am sure you are gaining an appreciation of the importance of vectors, and just how important it is for graphics and game developers to have a firm grasp of them both conceptually and practically. Trust me, this chapter won’t be the last time you see them. The mathematical concepts we explored in this chapter might appear to cover the same ground over and over concerning calculating points and vectors, but this should only convince you further how important these methods are.

Lines are far more complex than they first seem. Although most straight geometrical elements are called lines in a general, collective sense, the differences between vectors, lines, line segments, and rays are clear. Each has its place in graphics development in data structures and drawing, though we can apply many of the same mathematical calculations to any of them. Is it any wonder that many of these are stored in the same data structure of pygame.Vector3?
