We live in a 3D world. Therefore, for us to convincingly fool our users into believing that their reality is being augmented or altered, we need to work with their world in three dimensions. Now, each of the platforms we are working with (web, Android, and Unity), all have 3D engines we will be using. In the case of Unity, it is the 3D engine and without a doubt the easiest to use with little or no programming or math knowledge required. Android and OpenGL ES is a distant second, as it will require some knowledge of 3D math. The third and last option is our 3D engine for web, which will be three.js library. The three.js will be the most difficult platform to work with when using 3D, which makes it our perfect candidate to start with.
The Unreal platform, as we mentioned in Chapter 1, Getting Started, is another ARCore platform option. Unreal is similar...
