标准化值是什么意思?

问题描述

我目前正在研究OpenGL中的照明，该照明利用了GLSL中称为标准化的功能.根据OpenGL文档，它说它计算两个向量的归​​一化乘积".但是，它仍然没有解释规范化"的含义.我曾尝试在Google上查找标准化产品，但是似乎找不到任何相关信息.谁能解释归一化的含义并提供归一化值的一些示例?

I'm currently studying lighting in OpenGL, which utilizes a function in GLSL called normalize. According to OpenGL docs, it says that it "calculates the normalized product of two vectors". However, it still doesn't explain what "normalized" mean. I have tried look for what a normalized product is on Google, however I can't seem to find anything about it. Can anyone explain what normalizing means and provide a few example of a normalized value?

推荐答案

这是一个数学术语，并且此链接用非常简单的术语来解释其含义:

It's a mathematical term and this link explains its meaning in quite simple terms:

1. 然后计算其长度
2. 将其每个(xy或xyz)组件除以其长度...

1. calculate its length, then,
2. divide each of its (xy or xyz) components by its length...
