 当用到矢量和三角学函数时，```vec2```, ```vec3``` 和 ```vec4```被当做向量对待，即使有时候他们代表颜色。我们开始把颜色和向量同等的对待，事实上你会慢慢发现这种理念的灵活性有着相当强大的用途。

 一旦我们得到角度和长度，我们需要单位化这些值：0.0到1.0。在27行，[```atan(y,x)```](../glossary/?search=atan) 会返回一个介于-PI到PI的弧度值（-3.14 to 3.14），所以我们要将这个返回值除以 ```TWO_PI```（在code顶部定义了）来得到一个-0.5到0.5的值。这样一来，用简单的加法就可以把这个返回值最终映射到0.0到1.0。半径会返回一个最大值0.5（因为我们计算的是到视口中心的距离，而视口中心的范围已经被映射到0.0到1.0），所以我们需要把这个值乘以二来得到一个0到1.0的映射。
