In this chapter, we completed the last of our major setup tasks for the ARCore environments we will explore in later chapters. We first jumped in and installed the prerequisite AR-enabled experimental Chrome browser. Then, we downloaded and installed Node.js as a requirement for running a simple HTTP server. This gave us the ability to pull the examples from the three.ar.js source onto our local machine. We then used the HTTP server to serve up the sample AR web-enabled applications to our device. Next, we tackled the problem of debugging JavaScript code remotely to an Android device. After that, we took a brief tour of 3D and explored ways in which we could scale and transform 3D objects in our AR scenes. Then, we finally learned that good knowledge of 3D concepts and/or math is essential for our success as AR developers.

Now that we are done with the essential setup tasks, it is time to move on to building AR applications of our own. In the next chapter, we will explore the AR concept of motion tracking using our web platform.
