Description描述

Returns this vector with
a magnitude of 1 (Read Only).

返回向量的长度为1（只读）。

When normalized, a vector keeps the same direction but its length is 1.0.

当规格化后，向量保持同样的方向，但是长度变为1.0。

Note that the current vector is unchanged and a new normalized vector is returned. If you want to normalize the current vector, use Normalize function.

注意，当前向量是不改变的，并且返回一个新的规范化的向量。如果你想规范当前的向量，使用Normalize函数。

If the vector is too small to be normalized a zero vector will be returned.

如果这个向量太小而不能被规范化，一个零向量将会被返回。
