Summary

Let's summarize what we've learned in this chapter:

We covered the history of WebGL and how it came to fruition.
We learned about common elements—canvas, objects, lights, and camera—that are, generally, present in WebGL applications.
We learned how to add a HTML5 canvas element to our web page and how to set its id, width, and height.
We implemented the code to obtain a WebGL context.
We covered how WebGL works as a state machine and, as such, we can query any of its variables using the getParameter function.
We got a glimpse of the interactive 3D application that we'll build by the end of this book.

In the next chapter, we will learn how to define, load, and render objects into a WebGL scene.
