Education is an important application of augmented reality. Children of all ages love astronomy and studying the planets of our solar system. So, for this project, we're going to build an educational AR app that will let you explore the solar system and view the planets in the comfort of your living room.

In this chapter, we are going to build a model of the solar system, including the earth, moon, sun, and the other eight planets (yes, Pluto still counts!). We will use actual NASA data to set up the size and texture of each heavenly body. We will animate the planet's spin and orbit using C# programming.

We'll use the primary AR technique of using coded markers to implement the project. We'll print cards with AR markers you can use to interactively explore celestial bodies. We will also show you how to make a markerless version of the project...
