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

• We've reviewed concepts, architecture, and code that has been developed throughout this book.
• We built a 3D virtual car showroom application showcasing how all of these elements fit together.
• We've learned that designing complex models requires specialized tools, such as Blender.
• We covered how most of the current 3D graphics formats require the definition of vertices, indices, normals, and texture coordinates.
• We studied how to obtain required elements from a Blender model to parse them into JSON files that we can load into a WebGL scene.
• We learned how to add a controls widget to provide customization functionality.

In the next chapter, we will get a sneak peek at some of the advanced techniques commonly used in 3D computer graphic systems, including games, simulations, and other 3D applications. After addressing these topics, we will also learn how to implement them in WebGL.
