Hi Freya, I'm somebody who dropped out of high school and has struggled to grasp math concepts for a very long time. I'm 29 and it has always seemed completely inaccessible to me. Sometimes your lessons make me cry a bit because I feel like for the first time in my life I'm actually able to comprehend the use cases for this stuff in a way that is both enjoyable to learn and actually useful. Thank you so, so much for everything you do ❤️💕
I cannot thank you enough for this. I follow you on twitter and you really have made some amazing stuff, it's so great that we get a literal full workshop's worth of knowledge, straight from your mouth. Understanding math at this level could easily kickstart a whole life's worth of game development, and so SO few people really understand how to use it, this series will definitely change some lives. AND I AM READY. Thanks thanks thanks thanks thanks
I`m grateful like that too, I`m just watched few times the Linear Alg series from 3B1B channel and then the algorithm just recommended this video, so it`s all perfectly matching, the theoricals and practicals, thank you so much.
And this is the reason I love the internet. There are some things that I hate about the internet, but the free information that's available for *everyone* is so valuable, especially for less privileged people. Hope you're doing great with this, and good luck :D
These are honestly some of the best game/graphics dev videos on RU-vid. I rewatch the math and shader videos all the time because there's so much great information there and it just reinforces it and helps me visualize. It's been a huge help at my day job and in my hobby projects, so I appreciate the hell out of Freya!
Sooo cool of you to put this up to youtube! I got so much out of this course the first time around, having the ability to refer to a condensed version of it whenever I want is so extremely very nice. Thank youuuu
I use Godot, but your tutorials are absolutely amazing. Thank you for sharing your time and knowledge to help people like myself learn this stuff. You rock girl!
I learned more in a few hours than an entire semester of my vector physics subject during senior high. I agree with your intro statement where teachers really don't know how to make things interesting to students and just assume that everyone is willing to learn subjects voluntarily without giving how it is useful in real world cases or at least making the discussions interesting.
Vectors would be much more interesting to learn about if they were used as tools to solve interesting problems. Which is the genuine reason why they exist anyway.
I'm so glad I decided to rewatch this. The first few times I watched, I really didn't understand much beyond the definitions of vectors and scalars, but now that I've gotten some experience with vectors and scalars in games, everything else is starting to make so much sense.
Freya you are amazing! I've recently gotten into graphics programming and been delving into more advanced math to fill the gaps in my knowledge, and this is EXACTLY what I needed. 3blue1brown is great, but it can get a little abstract and I always end up thinking "cool, but what can I do with this?". The way you tie it to game dev and give real-world examples makes it much easier to grasp imo. Thank you so much, you're a great teacher!
These series are something I've been searching for for a long time. I set a goal to watch every math tutorial and work hard. Thank you for making these videos for strangers like me who need them
I almost began to cry at how helpful this is. the fact that you started with the basics makes this so so so very friendly and intuitive, i can’t even put my gratefulness into coherent words. thank you infinitely.
if i had someone like you as my math teacher when i was younger i‘m pretty sure my dyscalculia wouldn’t have traumatized me to the point where even the thought of math can be triggering. this is so well explained and soothing and genuinely makes me want to learn. thank you
I've been working on a game for almost 2 years with no prior knowledge, and I've been hesitant to learn math-related stuff coz I hated math when I was in school. Eventually, math problems really did appear and I wish I knew these stuff before I did some of those. Now I want to learn more! Thank you for these videos. Amazing job!!
Took a Vector Calculus course in my college Computer Science program almost 30 years ago. Got an A -- then somehow forgot almost everything. This video brings back good memories. Thanks for the memories.
you got the best game dev explanations out there. have a great skill for explaining quite complicated things in simple terms, which is a skill in itself.
I consider myself a bit of an intuitive and clever scripter, but I never did get any formal education in higher or specialized maths. Thanks for helping me brush up a bit!
These lessons are so awesome and Im actually looking forward to learning math! I think the problem with schooling is that they never get you excited about it's possible applications, at least my teachers never did. If they told me how it could be used creatively I might of actually paid attention lol.
If you're only learning to try and get something material, every second of it will be like pulling teeth. It's a bad attitude, and you can let go of it anytime.
Just want to echo what others have said, after years doing 3D artwork and recently trying to learn VEX for Houdini, but not fully understanding vector maths, it's now really clicked after watching this. Just brilliant! Your style of explaining is fantastic. Thank you. Really looking forward to watching all your content.
Thank you! I had a problem with understanding the whole concept of vectors, but you explained it perfectly and now I think I'm ready to use them efficiently.
This is brilliant. Thank you Freya! Love that you're showing all these concepts in context - it's really helpful. Your students are lucky to have you :)
Math applied on practical uses for games is so much enjoyable and much much more understandable than how you learn it on school. The dot product for the volume issue was so cool. I liked math on school but this is just much more cooler, is like analyzing ordinary physics of our real world into a game, I love this.
It's always a good sign when the teacher is using professional audio gear for a maths demonstration. AKG are underappreciated for sure, being a producing metal musician, I try to help out with production mix on all videos when I can and you know what's up. So, translating these values, classes, and functions into arrays is difficult for someone that struggles to apply the concepts into code. I'm trying to learn python after a short run of learning c++ basics some years ago, because python is maths and ease of use is more efficient for learning and applying in linux programs. Thank you for all of these.
When I was noobier, I almost always forgot to normalize vectors before dot operation. When for some reason normalization not needed, put both vectors at world center first. Polygon normal still need to be normalized too, because there are possible situations where it's not length of 1… I had that in Houdini, though it's rare. Also I've found trick in Unreal Engine, casting Rotator to Vector returns normalized vector.
transwoman from that bunch of gravel and clay across the sund here, I had to quit trade school (electrician) due to the predominantly male students being awful and threatening to me game development is my life long dream and an absolute brick wall, your video on bezier curves was amazing. You inspire me and you are a huge help in brushing off and polishing my highschool maths. I am planning to qualify for studying physics at university by august but until then I decided to program as much as I can with gamedev as a focus.
Thanks for youtubeing this. Really. Maths look really scary and your way of explaining them makes them easier and approachable. Not many teachers achieve this, ever.
This is soo good. I cant even exaplain to you how useful I found this. I came with 0 knowledge of 2D/3D vector maths, it was always monkey see monkey do. But now I actually understand them. Thank you so much!!
This is fantastic. I only just stumbled onto your channel, through your Bezier curve video. And though I love maths channels like 3b1b, the only time I really get to play with what I consider fun or interesting maths is in video game development (last time I touched a Bezier curve was when I was writing a game entirely in C++ using only Assimp), so this is a perfect marriage of theoretical knowledge and the kind of practical application that's relevant to me. I haven't done any game dev stuff for a few years, so maybe this will get me back into it.
This was great! I just implemented some code in this submarine simulation prototype I'm working on that gives me the subs speed... I basically found someone else's code and was able to duck-tape their code into my game, but I had no idea how it worked after I got it working... now everything makes sense to me and I'm thinking about things I can do with Math I never thought about before!
Thank you for this. My dad has a PHD in mathematics and as a kid would try to teach me. I found that my biggest hurdle with math is most if not all teachers would explain math and how to do it. But they never really explained WHY one would even want to do it. Im still terrible at math but because I work in the industry I realize that it can greatly help me, even if Im not directly making awesome plugins and just rigging and doing basic tools for animators. Cheers!
MATH is so essential for everyone 's day life not just for an IT guy. I am happy to find some time to be back here to brush off my math knowledge also enjoying watching your teachings on MATH. I wish you could be my teacher when I was at the university, I would love MATH more!!!
You have a great mind!🙌 You are the kind of person conservatives love to hate. You are intelligent, compassionate and speak truth. That's their weakness. We need A LOT more people like you. A lot more.
I'm here trying to learn vector math, click this video, and only find out you're the developer of one of my favorite VR games i've seen. I haven't watched all of the video yet, but I'm excited.
I've decided I'm not going to go to University anymore since the professors don't teach you anything except tell you what you need to learn. I think everyone is capable enough to do a simple google search and learn new things. You're awesome and thank you for being my math professor.
dude.. this is absolutely f*#$%ng amazing. showing the math, then showing the code, then showing it working in unity.. Tho i wish this was in unreal this is still extremely unique to see someone teaching these things in this much applied depth... thank you so much for this. kinda makes me wanna learn c#. bless you for this...
Hey I just wanted to say... I started making games about a year ago, and when I first started with Unity I was so lost. I tried making a platformer at the start and it sucked soo bad... Like the animations where off, I barely got the char to move (suprised I did and at the time i legit just copied and pasted)... after loads of failing and trying again, I found myself at a very dark place, questioning if this was for me, making games uk... But then i came across this I think it was around march this year... And honestly it has helped me more than any other gamedev video out there... I can't thank you enough for what this did to me... If any of my friends ever wanted to get into game dev i'd definitely start them out here... It explains soo much of the thought process when making games too, (ive since realised 2 games for game jams and am working on a new platformer currently )
What a great lecture. Very clear and detailed explanations. This helped me so much with some vector concepts I was having problems really comprehending, like normalization. I understood it returned a vector with a length of one, but that was it. You explained it and everything else very well.
Introduces herself as oh yeah I also once made a plug-in a long time ago called “Shader Forge”! Like WHATTTT!! That’s my favorite tool ever!!! I literally used shader forge everyday for years
This is an amazing tutorial series! I didnt have vectors in school back then so this is helping me alot in uni now. Thank you so much and keep your style of education. The speed really is just right
I've only randomly dipped into a her livestreams a few times and still I've learnt things just from passing by on Twitch. She's kinda awesome, making all this really good educational content available for all
When I figured out the the coordinate (-1, 1), I got so happy cause I'm terrible at math but for game developing I'll do anything, I'm 17 tho, I wanna get a job a buy a good PC and learn to code, I love videogames
Thank you so much for making it easy for me to get past the hurdle of learning game math. I've been fudging it for months now, putting off actually studying because I thought a class would bore me to tears. Your explanations are great, and the practical examples are exactly what my ADHD brain needs to stay engaged (and it doesn't hurt that I can pause the video whenever my mind starts drifting lol). Great work!
Thanks a lotttt for intro, lots of stuff to learn from the intro part itself for me - i have learnt maths from lots of places, but no-one talked about these stuff. So, thanks a lot for this general but very important stuff. 0:25 Shaderforge Plugin for unity yielded good income -- 0:58 "two full time salaries" - umh, full time for what duration? full time for 2 months u mean? 1:35 Going to GDC and talking to industry people is important 2:05 "usually got a lot of questions...." 3:05 image in fellow colleague's eyes is crucial - i forgot sooo much about this. thanks for reminder 4:13 what will assignments look like 5:04 other stuff
in regards to this, you can post these intro sections only as short videos when u have nothing else to upload. Sort of like how the people at Ted have been doing lately.
Ted: ru-vid.comvideos one such example of short extract from a much older video uploaded recently: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-g4IAa8wZlqU.html
Good video and a nice refreshment of 8-9th grade school math and the usecase of dot product was interesting, it help a lot. A little advise: Next time try to move the canvas a little bit less often, cause move it every second is a little bit take attention from the important stuffs at least for me. Also a little bit less correction on the writing, no need to be perfect shape letters/numbers on canvas, we can read it :)
The kitten is the second best part of this They have such a cute meow The best part is finally learning this math in a fun way after public school ruining it for me with constant homework and no purpose of learning it, being able to visualise it helps so much, thank you!
I have nothing to do with dame dev but for some reason I ended up here and am absolutetely amazed by these videos. I should do so many other things, but just cant stop. Thanks a lot for this!:)
The direction vector from A to B (starting point A to destination B) is (b-a); (b-a) in words is the "destination point minus the starting point". This is following the pattern already established in using the origin as the "pseudo" starting point when defining an arbitrary general vector at point A or B or C...; in words a vector defined as the "named destination point minus the 'pseudo' starting point (0,0,0...)". In practice you can still calculate the length and the distance of a vector that starts at the origin. The big take away is that two or more vectors can have the same direction but different starting points, none of which need to be the origin and every direction is possible from any point. The vector normalized to unit dimension strips out the length of an arbitrary vector by the operation of division.
This is AMAZING! Sincerely, thank you so much for this series. I've just recently found this channel and I plan on digging through every video. You're really, really good at teaching.
I'm taking a break from college after being somewhat burnt out on studying maths. But Something like this could get my enthusiasm up a bit. Just seeing your title piqued my interest.
Hi there! Just bumped into this video by accident (been studying 3d math for a few months for a project with fractals) and found out you created the best plugin for unity I ever used! Shaderforge is a masterpiece and I am honored and very pleased to meet you!
To verify the 3rd exercise, one could add a transform as a child of the first point and set it the calculated coordinates of the world space point. That way, if the formula is correct they should stick together! Thanks a lot for this video Freya! :)
I have been coding since the age of 19 when I did a hand reverse engineer of a C64 program and learned 6502 assembly in 2 weeks without a computer... but THIS is all way above my pay grade, i never had ANY math at all and after 30 years as an embedded developer it has rarely caused me any pain.... other than wishing I had learned it :) However. You are wrong. There is ONE stupid question. the one that goes unasked.
I do not particularly like coding, but you have brought me the closest to enjoying it. I do it because I know it's an important skill, but thank you for making it more than just learning for skill, but learning for fun. :)
Yeah I remember back in Unreal Tournament 3 days, I wanted to see how materials done and wtf are these yellow-green-red-black squares everywhere. Few month later I realized it's UV texture coordinates, and it was vector field. It was first time I learned where vectors are used.
