译文
根据Unity官方文档给出的定义:
切线是单位长度的矢量,它顺着网格表面沿水平 (U) 纹理方向。
意思是切线与每个几何面 UV 的 U 坐标轴方向一致。

在第二章节的6.0.1小节中,我们将详细介绍这一属性,包括如何计算模型法线贴图的副切线。
原文对照
According to Unity official documentation:
A tangent is a vector of a unit of length that follows the mesh surface along the direction of the horizontal texture.
What does this mean? The tangents follow the U coordinate of the UV on each geometry face.

Later in Chapter II, section 6.0.1, we will review this property in detail and include the binormals for the normal map implementation on an object.
