Overview of this book

Mathematics is an essential skill when it comes to graphics and game development, particularly if you want to understand the generation of real-time computer graphics and the manipulation of objects and environments in a detailed way. Python, together with Pygame and PyOpenGL, provides you with the opportunity to explore these features under the hood, revealing how computers generate and manipulate 3D environments. Mathematics for Game Programming and Computer Graphics is an exhaustive guide to getting “back to the basics” of mathematics, using a series of problem-based, practical exercises to explore ideas around drawing graphic lines and shapes, applying vectors and vertices, constructing and rendering meshes, and working with vertex shaders. By leveraging Python, Pygame, and PyOpenGL, you’ll be able to create your own mathematics-based engine and API that will be used throughout to build applications. By the end of this graphics focussed book, you’ll have gained a thorough understanding of how essential mathematics is for creating, rendering, and manipulating 3D virtual environments and know the secrets behind today’s top graphics and game engines.

Summary

In this chapter, we’ve created code to force the errors incurred when trying to plot floating points in whole-number pixel locations. Mathematically speaking, the focus of the chapter was on Bresenham’s algorithms for drawing lines and circles that take the respective equations and create a raster image from them while working with integer values to ensure a pixel-perfect drawing.

In Chapter 4, Graphics and Game Engine Components, we will explore the structure of graphics engines and look at how they are put together to cater to the numerous functions they need to serve.
