That is why buffer++ works -- it is incrementing by a single vectorlength, which is 16 bytes.
这就是 buffer++ 能够工作的原因 —— 它是按照单个向量长度增长的,也就是 16 个字节。

This is a normal vector of the same length as n, well, up to sign.
这是与N长度相同的法向量,只是符号不定。

A sequence is a variable lengthvector that has two characteristics: a maximum size, which is determined at compile time and which could be unlimited; and a length, which is determined at run time.
