Chapter 8. The Isometric Worldview > Introduction to Isometrics

Introduction to Isometrics

Sometimes explaining and understanding a concept is easier with comparisons. With this in mind we will briefly discuss 3D in games in general and then specifically talk about isometrics.

It is rare today to find professionally created games for sale that are not 3D. Even games that are typically only two-dimensional, such as card games, often have some sort of 3D element. As mentioned in Chapter 1, “First Steps,” 3D can be applied to a game in many ways. Games like Unreal Tournament use a real 3D engine. A 3D engine can rotate objects and display them correctly onscreen, changing the camera's viewpoint at any time, and uses very detailed z-sorting. Z-sorting is the concept and act of placing one object on top of another to give the appearance of it being in front. (In Flash, the objects we'll work with will be movie clips.) The sequence in which we arrange the objects is called the stacking order. Each object in the stack is at a specific depth—assigned by a relative numeric value—also known as a z-index. Z-sorting can be applied to several different types of situations including a 3D world (as in this chapter) or the open windows of your operating system.
