等距投影是一种至少从80年代早期就被用于电脑游戏的技术。这是一种快速有效的模拟三维空间的方法，给你深度的错觉，而不需要在“真实的3D”中进行大量昂贵的透视计算。在早期，大多数视频游戏都是自上而下或横向滚动的。Zaxxon（见图3-1）和Qbert（见图3-2）是第一个商业等距游戏。
Isometric projection is a technique that has been used in computer games since at least the early ’80s. It’s a quick and efficient way of simulating a three-dimensional space, giving you the illusion of depth without a lot of the costly perspective calculations you have to do in “real 3D.” In the early days, most video games were top-down or side-scrolling. Zaxxon (see Figure 3-1) and Qbert (see Figure 3-2) were the first commercial isometric games.
