And to find the height of this thing, I need to know what actually the normal component of this vector is.

为了求出高度，需要知道这向量的垂直分量是多少。

This means that they can be vector based and, therefore, you can provide a common component that can be used at a variety of resolutions.

这意味着它们可以是基于矢量的，因此，您可以提供一个公共的组件，在各种不同的地方使用它。

Only the direction of the vector, the ratios between the component amplitudes, is important.

只有向量方向，即分振幅之间的比值，是重要的。
