在现在的图形渲染管线中,3D的向量要么存在高带宽的寄存器(registers)中,要么存在中等带宽的计算机内存中,要么存在低带宽的磁盘中。针对于单位向量,寄存器由于对速度有着极高的要求,往往希望你能够将其以float32*3的形式进行单位向量的储存,而磁盘往往更希望更有效地利用存储空间,因此会鼓励你进行各种的编码/解码操作。
Face of a control volume with varying normal vector in 3D. A face vector S→ of an hexahedral control volume, like that rendered in Fig. 4.1b, is most conveniently computed using the same Gauss's formula as employed in 2D for the area of a quadrilateral. Thus, e.g., for the face ...

The method used in Cry Engine 3 for compressing normal vectors is irrelevant here, because it has a limitation that the z component cannot be -1. Since it's only designed for view space normal vectors, those vectors should not point away from the view. However, in our system, we need t...
