In this chapter, we are going to look at four different methods to create large worlds for simulations, games, or animations. We are only going to present the code necessary to accomplish this and not elaborate further. You should combine the methods learned here with the topics presented in the previous chapters to develop complete applications. In addition, we will use very simple graphics in our scenarios and assume that you would spend more time on art and story (as described in Chapter 5, Interactive Application Design and Theory) for your own work.
