Coding Math: Episode 54 - Dot Product

Let's take a look at what "dot product" is - a couple of ways to calculate it, and some uses for it.

This channel is awesome. It will help me with me a lot. Thanks for creating all these videos.

[RagePower]

This is the best channel for programming math. Thank you so much.

Love your videos. Having gone through most of them I have a better understanding of the math I need to use in some unity experimentation. Finally a good explanation of the dot product, which should make certain things in shaders easier to understand whats going on. Hope you'll cover the cross product at some point soon.

Could you not also get the angle of the two vectors by atan2(p2.y, p2.x) - atan2(p1.y, p1.x) ?

proper visualisations, i am liking this

[ricardo.mazeto]

Great tutorial as always. Do you have any plans to start a rendering tutorial? That would be soo cool!

[rameynoodles]

Could you make that video about Line Collision Detection with Dot and Cross products that you said you might do, now that you've got a video on it?

[abidmahmud]

sir make some tutorial about tree and graph programming. Your math and physics programming tutorial is the best..I hope u will accept my request....

This is awesome, now I'm nearing the end of your teaching, what am I to do ? I've been doing this everyday in Lockdown, (I know, I'm not as fast as the rest of you)my computer is files of code, my scrapbooks are pages and pages full of code. As this is the best channel here it looks like I'm going through it again. Practice eh?
Keith, thank you.

@Keith I have a tutorial request: the math behind distributing objects evenly on the surface of a sphere, or animating to another point on a sphere with the path fixed to the sphere surface. THANK YOU!

Thank you, could you show how two ball elastic collision like billiards game in future episode ? My English isn't very good, please don't mind.

Can You Please Please Please Make A Video Series On Javascript Implementation Of SAT(Seperating Axis Theorem) Collision Detection. I Was Reading Some Articles On That Subject But I Cant Implement It In Javascript, So Please Make A Video Series On SAT I Will Be Very Glad To Learn SAT.
