In this chapter, we discussed how a Shader works using a GPU and how to create our first simple Shader to achieve a nice water effect. Using Shaders is a complex and interesting job, and in a team, there are usually one or more people in charge of creating all of these effects, in a position called technical artist; so, as you can see, this topic can expand up to become a whole career. Remember, the intention of this book is to give you a small taste of all the possible roles you can take in the industry, so if you really liked this role, I suggest you start reading Shader-exclusive books. You have a long but super-interesting road in front of you.
But enough Shaders, for now—let's move to the next topic about improving graphics and creating visual effects with particle systems!
