Chapter 5. Image Rendering

5. Image Rendering

One of the key elements of Sir Lamorak’s Quest—and, in fact, all games, unless you’re thinking about the old text-based adventures—is the ability to render images (sprites) to the screen. Without graphics, the game would be pretty dull.

In this chapter, we run through the key concepts needed to render images to the screen using OpenGL ES. We cover the basics of rendering triangles, texture mapping, loading textures from image files, and improving performance.
