The Dot Product - A Visual Explanation

Even though she's saying nonsense but i trust her she looks like a 🤓
In a good way though 🤓😊👍😂😉😜😔😞

i try to watch this video but not playing just circle is moving

Now I need English version.

Beautiful explanation, concise and simple. Thank you

Thank you for a good a concise answer to my question! 🤝

Simple and get to the point, thank you!

Thank you SO much! I only found a lot of mathematical explanations. This little drawing explaining that it's just one vector projected onto another, was all I was looking for.

you’re amongst my favorite persons now. Great explanation <3

TYSM for the video! literally could not find another answer to my question of what the dot product is "saying" and you had it in literally the first 5 seconds.

This is so beautiful I finally get it!!! 😭

Very thanks!!!

Thank you

ty !!!! this helped a lot !

This is a really interesting way to conceptually understand the dot product, thanks!

Looks awfully similiar to cosine

wow wtf i did not expect to understand this in literally 50 seconds LMAO thank you

And then cross product to see if A is to the left or right of B. Fancy way of knowing whether your rogue can apply that nasty backstab multiplier or tell your AI driver to steer left or right to avoid stuff in your level! ;)

Thank you so much!

Keep up the good work!

Amazing!

just solved my problems in about 45 seconds thank you!

Great video! I appreciate how concise this was!

NICE!
Im going to use this to confirm if my bots are facing their target's before they can attack within a FoV!

Damn, i have seen hours long videos on dot product! When you know, you know! Thanks Freya..

Thank you for your video!!

damn, that a pro explanation 1m and I understood perfectly lol

i think you meant to say parallel hehehehheheeeeeee

wow this explained it really fast

This actually makes perfect sense! Now i perfectly understand how dot products work in my code

man, whenever im trying to understand some game dev math stuff i really should come to this channel first

you are a live saver!

@Freya what does "normalized" vector mean that she talks about in her description!?

brilliant explanation, thank you so much for the simple illustration

Nice

Thanks a lot🎉

I wish I could tick a "love" emoji instead of just like. Most concise explanation I've found so far.

Wow this explanation is crazy intuitive, thank you so much

What about Z axis?

made my day. happy to find your channel

Such a good explanation

Only if the module of both vectors are 1... Cuz dot product is a product of 'the parallel part of b in respect to a' and a

Very helpful video!

now I understand how the hessian normal form works (you only normalize the normal vector in that one), thank you miss Freya!

Very helpful, thanks a lot

Am a senior engineering student and never quite thought about it this way. Props!

my fix was to normalize them...

I'm sorry if this come off as a dumb question, i'm not really good with math,
For this to work rightly the 2 vectors must stem from the same origin right ?

This is not quite accurate. In reality, u⋅v = magnitude of the projection of u unto v times the magnitude of v. she said that it is simply the magnitude of the projection of u unto v.
