In gaming applications, textures are the key factors that affect the performance as well as the look of the game. The size of the texture and intelligent use of concepts, such as mipmapping, will decide how your game would perform. Also, we learned how to map texture coordinates to vertex coordinates, which is a very important concept to control the overall memory footprint of your objects in the GPU. If you plan to use open source WebGL libraries to create your games, these concepts will come in handy as you might have to tweak them to get the last bit of performance from your game.
In the next chapter, we will learn about the different types of camera used in 3D games. We will also write a new Camera class to view our world in 5000 AD with different perspectives.
