That is what the forum is here forI am sorry for opening a topic for this but i am unable to get correct keywords to search for this.
The dot product could be any value. It's the projection of one vector onto another vector.If i do "dot" operation on two vectors i get value in between -1 & 1 right?
Hot to scale it proportionally to get it to 0 - 1 range?

Thanks.
I am sorry but that link you gave is useless to me as i dont understand that matematical symbols, have any basic one to understand those?

A · B = A_{1}B_{1} + ... + A_{n}B_{n}
The dot product is thus the sum of the products of each component of the two vectors. For example if A and B were 3D vectors:
A · B = A.x * B.x + A.y * B.y + A.z * B.z

I think his point is that you have to know the math to understand all the articles, but if you know the math then you don't need the articles. That's what I got from his meaning of "pointless".The books and links are referencing algebra and calculus formulas. Which are quite central to games in general. I do not enjoy just the theorems particularly either, but calling them 'pointless' is a little harsh.
