这一向量就称为法线向量或简称为法线。
计算手掌相对于控制器的法线向量。
Calculates the normal vector projecting from the hand relative to the controller.
这些报告包含空间位置加上他们的法线向量，几何(如立面)相对位置。
These reports include the location in space plus their normal vector, relative to the geometry (e. g. the facade).
首先我们从名字上开始分析，所谓“法线”指的是垂直于平面的向量，我们使用这个来计算光照。
Let's break the name down. The "normal" is a vector perpendicular to a surface, which we can use to calculate lighting.
由于立方体有8个顶点，支持法线的方法之一就是指定从立方体中心指向各角的向量，如图7a所示。
Because the cube has eight vertices, one way to supply normals would be to specify vectors that point from the cube's center toward its corners, as Figure 7a shows.
沿着法线反射向量。
我做了一些研究，我遇到向量、法线等，但我不了解他们属于我的特别的问题。
I've done some research, and I've come across vectors and normals and such, but I don't understand how they pertain to my particular problem.
