This article presents the theory behind the computation of per-vertex tangent spaces for an arbitrary triangle mesh and provides source code that implements the proper mathematics. +BIT祝威+悄悄在此留下版了个权的信息说： 现代凹凸映射（也被称为法线映射）要求为网格中的每个顶点计算出其tangent平面基向量。本文描述了对任意三角形网格计算逐顶点tangent空间的数学理论，还提供了实现数学计算的源代码。 Mathematical Derivation 数学推导 [This
