Have you ever wondered how video game graphics have become incredibly realistic? How can GPUs and graphics cards render such incredibly detailed scenes? Well, in this video we're going to explore how just a bunch of data in your computer gets turned into realistic graphics. Additionally, we'll take a quick look into Ray Tracing, DLSS or Deep Learning Super Sampling, and many other complicated aspects of video game graphics.
We at Branch Education love to play video games, so this video has been one of our favorite ones to make thus far. It's kind of like getting to look under the hood of your childhood car. Also, it was surprising that practically all video games use similar basic steps to render each frame. Furthermore, as a fun fact, to create this video our team used 1x 3090ti, 3x 3090s, and the model that we tore down was a 3090.
There are just sooooo many topics in the realm of computer graphics that we couldn't cover. If you're interested in part 2 where we'll cover things like UVs, Normal Maps, Shadows, Reflections, Specular Reflections, and much more, tell us in the comments.

This has been one of our favorite videos to make thus far. In this video, we covered the core steps of the video game graphics algorithm. We are debating making a 2nd video on some of the more advanced topics such as how shadows, reflections, and specular highlights (metal shininess) are calculated, as well as UVs, Normal Maps, Deferred Rendering, and other topics. However, 'part two' videos are tricky on UA-cam because they rely on the viewer watching the first part, and there's always some level of attrition. So if you want a Part 2 / 2nd video on this topic, comment below on your interest.
DANG
Please do a part two!!!! 🎉🎉🎉love your videos!
Please !!!!
When are you going to make a video on making one of your videos?
Highly interested.
I'm a professional graphics engineer and this is one of the best videos covering this topic. I will be using this video for newcomers to the field.
That's my dream job, but I don't know where to start to turn this passion into a job. I would be very curious to know about your experience and how you have reached this point in your professional life.
University or intern ships in game development can be your first steps i guess.
Nice bro, appreciated
@@tommytek_bs Learn math, learn math, and also learn math. So important for this topic.
@@marcel151not just any math. Heavy focus on coordinate geometry, trigonometry and calculus
The amount of work behind this 20 minute video is amazing. I am not taking it for granted.
Surely more work than most of the low level trash games on Steam
fr
FULLY agree!!!
I know, I was just wondering how long it took for every shot with the wire frame switching back and forth. It's not just switching off or on. It fades across in a nice smooth way that really communicates.
Not to mention all the raster triangle parts!
Demonstrating anti aliasing very well!
man I'm wondering how long it took and how many engineers worked to design this
People are like "I hate math." Your computer rendering a video game is nothing BUT math, computed at billions of times the speed of the human brain. It's virtually magic what they can do these days, and how powerful rendering technology has become.
🙏
Okay? I hated anatomy but I still really appreciate the doctors who are able to help me heal when something is wrong
Please continue to make these videos they are absolutely amazing. You focus on the parts that matter. The simple things. Adding in just the right amount of math and explanation to make it clear and concise. Explaining what we aren't covering in the video and where those concepts land the the scheme of things. Its just perfect. I would however watch endless videos no matter how detailed you get. This is actually one of my favorite channels on youtube. I remember watching my first video of yours about starlink and have been hooked since. You know how to tow the line between being bogged down in complexity and broadening the concept. Maybe i'm just a much more visual learner but to me everything makes perfect sense immediately. Its rare to be able to understand things so much better so quickly. Even when you cover things I am already familiar with it deepens that understanding with the visuals in a way my mind may have previously made more convoluted.
This channel, and this video, is the most underrated in the youtube algorithm. Instead of junkie videos that the majority consume, I wish it was videos like these that deserve the spotlight and recognition. This is amazing work and I hope there is nothing out there that forces you guys to slow down
So true
Ironically, the algorithm did get me to this channel. But I agree it is through personal tuning versus a proper display more on the front for "everyone" to discover. I definitely remember it wasn't because of UA-cam randomly recommending it. A true shame indeed. Hopefully the likes and the comments help enough to keep on trucking.
How this video could be underrated if it was just posted?
@@Sekhmmettstill underrated
Algorithm knows most people have the attention span of a reel, most people wouldn't get through the intro of this video
This is genuinely a 20 min long master class and the fact that we are able to watch it for free is crazy. Thank you team branch Education for such awesome content.
comment for the algo :D
Ikr it’s insane
They have 1.6 mill + subs and this video got over 2m views, I'm pretty sure you are helping them by viewing this as much as they're helping you with the information
So no this is not free
This video left me with tons of questions, but now I actually feel equipped to know what those questions are and how to find the answers. This summarized the topic more clearly and more succinctly than dozens of articles, books, and even college classes I have taken. I have made a few games as part of classes or for myself but understanding how all of that ended up on the screen was still a mystery to me. This video was great. You took time to explain terminology and provide definitions. The way you explained how the matrix operations fit in without bogging a beginner down in needless details - well I can't even begin to say how helpful that was. Thank you so much, this was excellent.
One of the best channels on youtube! Shared it in my group chats, thank you!
I've been playing video games for over 30 years and been a professional graphic designer for over 12 and I've never seen such a clear and well produced video explaining how video game graphics work. VERY impressive.
As a game dev, this video will make my life that much easier as an introduction to newcomers to the field. Beautifully crafted, guys! Kudos!
indeed, this video came at the right time because im planning to get into UE5 for the first time.
Me too.
Bro pls send me something
Bro send me too😂
Oh no, I was not asking for money, I said I'm a developer too lol.
Another incredible detailed explanatory video! Thank you for taking the time to create it. Looking forward to more advanced topics.
The narrator is so chill and awesome to listen to. And the videos have the vibe of an old 80s-90s science video you'd watch in school. I love these
I genuinely learnt more from this video than I did while studying “Graphics Engineering” in college for an entire semester😅
=)))))
no you havent
you're either a bad student or your college sucks
@@Decenium he probably has
@@crossovo just because you find it easier to understand in a video doesnt mean youre a bad student. College literally does not teach you anything but to make you self validate for a piece of paper which is called a degree for wasting 4 years sitting to hear a random guy yap all day. You can learn much from a 5 min video than a college semester.
What a wild video. 30 Years of gaming and never have i understood the mathematical complexity involved in the more modern games. Honestly breathtaking. Now playing AAA modded games in VR obviously takes these calculations to the next level. What a time to be alive. Great video guys!
I guess it is especially astounding to us because we have not been there for its gradual increase into being this complex. I assume certain things that were groundbreaking 20 years ago are now quite simple, and the same will happen again to what we're witnessing now. But at the end of the day, the magical scenarios we have all found ourselves engaged in through the years of gaming are all just math and algorithms, very convincing math and algorithms.
While VR comes with many optical and form-factor challenges, it’s pretty much identical from a graphics pipeline perspective. You simply render two images from two cameras, one for left and right eye.
Things like DLSS and ray tracing are much “bigger” changes to the graphics pipeline itself, as well as the GPU hardware.
One of the ABSOLUTE best UA-cam videos of all times. It's just amazing the detail and the same time simplicity to explain a topic.
This channel is awesome. Love how you guys dont shy away from complex topics
As someone who works on
GPU Hardware Design, I didn't expect the video to cover so much of the subject. Thoroughly enjoyed the video and would highly recommend to beginners in the field.
what does that even mean, what do you do?
@@Decenium VLSI Engineer, Adreno GPU
I have lots of respect what people in your profession are doing. Keep up the good work.
That video is great but i wonder about one really big mistake in it.
You do not sort out fragments of triangles on the backside of objects by using the z-buffer.
The whole backface triangles will be eliminated between the vertex shader and the rasterization due backface-culling.
The described approach results in a mass of unnecessary computations. Nobody does that that way.
@@gehtsnoch2237 Indeed. But for someone who's new to Graphics, Early Z and similar techniques should be secondary. This video is targeted more towards them.
Easily one of the most underrated channels on UA-cam. So much good content and education broken down into layman's terms.
1,420,001 people are subscribed to this channel.
it's definitely not underrated..
ai generated channel
@@raul-km6mq Nah. It's a human.
@@ADEPS. 220 million are subscribed to Mr. Beast and 60 million subscribe to Dude Perfect. So compared to what "the kids" would consider popular and be more likely to consume. So yea 1.4 million subscribers vs tens of millions is pretty underrated.
I seen many times this video, after that UA-cam showed me (I randomly opens it). And I have to learn much more of the complexity of what it does a GPU.
A true masterpiece, the first video that I have seen on 1440p on my smartphone (other videos lags a lot on it XD).
I really hope that you will release soon the videos where you go deeper on this argument, because is very interesting for me that are studying all that a gamer needs to know to choose a GPU for the next Gaming PC (I'm sorry for the bad english, I'm italian^^)
Good job, really!^^
This was sublime. An incredibly well presented and easy-to-follow explanation. Props to everyone involved in the research, writing, and animation.
I work in video game development. I am a 3d artist. I know what normals and vertex’s and shaders are, but I never really understood how the algorithms that I work with everyday actually are calculated until I watched this. I have an artist mind not a mathematical mind. So this really helped by braking it down in a visual way so even I can understand it. Definitely would watch a detailed video on ray tracing and DLSS .
I'm a 3D graphics artist turned technical designer, I whish this video existed 10 years ago lol. It's quite something when you realize how all 3D is just a complete illusion, smoke and mirrors.
Same here! There are many incredible things that we are familiar with but never "try to know" how it work!
@@TeraPixel As a Tech Artist, my job description is literally smoke and mirrors. :p
@@AlessaBaker That is true, especially because i work almost exclusively with embedded systems where clients want good visuals with low cost hardware. 😁
@@TeraPixel Indeed, objects that only are made to exist as groups of coordinates. Although it's now more possible to turn them into real-life objects thanks to 3D printing.
Oh my god, I doubt the average person realizes how much work there is to create a video like this. You have my utmost respect. I pray for the day that your channel has 100M subs.
Bro called us npcs😂
@@deinsteinnyaberi5884 I. Certainly. Can’t. Realise. How. Much. Work. Was. Put. Into. This. Wow. Amazing. 🤖 😂
Amazing work! I've learnt a lot of the behind the scenes game engine mecanics
This is the best visualization of the rendering process I've ever seen. Thank you for your effort
It’s hard to believe that content of this quality is free. It amazes me the things that us humans have accomplished. Something that most people don’t give a second thought to, they just download a game and have fun playing it without thinking of the incredible engineering behind every pixel on their screen. It is truly awe-inspiring.
I was just awstruck after seeing the video! truly amazing
Totally agree with you! I can't stop calculating while playing COD :D
Sadly enough, we don’t give the ‘nerds’ who do all this enough credit.
You’re almost at 1,000 subs! I subbed btw.🎉🎉
@@AyJayEm23 Thanks lol took me 10 years. At this rate I’ll get my diamond play button in about 100,000 years!
I’m a graphics programmer in the gaming industry, and from my perspective, your explanation is very good. Good job!
Well... This was really just the surface of the tip of the iceberg, but noone was expecting a full Vulkan tutorial on how to replicate Unreal Engine level graphics in 20 minutes :D
That's not how graphics works... lol
You can easily get your assets from the unity store, you don't need to do all this stupid stuff!
🤤
@@FelixVyra >no one was expecting<
that'd be cool tho
Yeah. But it is held very, very simple. But that's good.
@@Alfred-Neuman What? What does this have to do with how graphics work in games?
I just found this channel, and it contains a bunch of topics I'm really interested in, instant sub. Great work.
Great video mate. Learnt some of these concepts in class but you just brought it all to life.
This is insane. I can’t believe we live in a world where this is free. Great job.
FREE?, buddy have bought ur own pc
FREE?
FREE?
@@__Paradox.UI__ i think he meant the video
You need a phone or PC and internet connection, not free.
This is absolutely incredible. I'm a programmer who's not into this field, but watching this video has made me appreciate how much goes into something we would consider normal
This is just normal work for anyone working with it (see what i did there)
Great work! Surely interested in a separate video on the more advanced topics
Got into modeling with Blender recently, this really helps put things into perspective, thank you
Please make another video explaining normal maps, shadows and shaders!!
Do not lose the narrator. He explains so well!
This is by miles my favourite video from Branch Education.
You know hes not the one who made the script right? If you didnt know that youre kinda stupid
I am pretty sure this is an AI generated voice.
@@RoXx1811No, it isn't?
@@RoXx1811narrator's name is Phill Lee as stated in the description mate. Stop talking out of your ass and respect the works they've put in.
probably, the most in depth information regarding a topic, i have ever seen
amazing video!!!!!
This is one of the most amazing videos I've ever watched, and I know all these basic graphics topics, looking forward to the more advanced ones.
This by far is the best 3D Animated video about 3D Graphics and Rendering. It's mind blowing that a GPU has to render upto 2 Million Triangles 120 Times in a Single second. Good work.
The amount of detail in this video is fascinating and as an aerospace engineer I am craving for much more those mathematical principles and detailed explanations. This should be a whole series. Can you add references in the video descriptions to the sources for learning more in depth? Thank you!
❤❤
He won't, that's his money trick
your money gone to trash
bro you wasted 20 bucks, couldve bought yourself a chicken parmesan lol
This was an amazing video! I never knew how much goes into such a “basic” part of video games. Thank you!!!
This video was rather complex in some parts, but it was enjoyable. This was a journey!
Please do keep making videos like this!
I teared up watching this. You turned a far-out concept into tangible information, all within the comfortable bounds of a 20 minute audio/visual masterpiece. Bravo👏🏼
@GM-hg7se annoying.
@GM-hg7se FO loser...
Truly mind boggling how computers do and how they do. I will admit I had once upon a time thought that computers had magical gems and unique stones (probably because star wars/the mummy movies possibly looney tune 0.o haha)
Im a software engineer who grew up with video game developer aspirations. Information like this wasn't easy for a child to obtain in the early days of the commercial Internet who didn't have the guidance for where to start. I'm just happy to see resources like this that demystify these subjects so that today's young minds don't face the same obstacles that I did.
Can you as a software developer work in the gaming industry?
I´m watching this and i have the admost respect for people like you. I´m sittings in front of my PC every day to play games and it´s just so hard to grasp that people where able to build tools to create apps and games out of nothing. I´m not able to do it and it´s just fascinating.
@@yusa58 I sure can. For myself, not as a game developer but I can definitely work on things like the multiplayer game servers. My desire to work in the industry is no longer there but if I really wanted to I'm sure I could find a way in.
@@yusa58As a game and software dev, I say yes.
Your animations are amazing. And i don't just mean that on a technical level. The way you manage to conceptualize the animations in order to explain the complex subjects so they're trivially easy is remarkable.
They're all things i know; but only after the hard-fight of having to read various bits over the years. GPUs, flash cells, memory circuits.
I'd love to see your animation style take on instruction decoding, asynchronous memory fetch, converting instructions to u-ops, speculative execution, branch prediction, and caches. (and how basically almost none of your CPU die is dedicated to computation, and it's all mainly re-writing your machine code and waiting for values to get into registers)
If i had any money to spare i would throw you some. These are so well made.
Really good learning video, very inspiring and motivating to know the tech in graphics. Thanks for mentioning me in the Patreon list.
The fact that videos like this, so simply and indepthly explained, are an amazing feat. Imagine if you wanted to know this information before the internet...
Honestly think just watching your channel would result in better results than a semester at college.
Bro was ignored😔
One of the best video's I have seen on UA-cam, very well done!
It solved many of my doubts I feel thankyou towards your hardwork
As a software engineer student, this was a very valuable watch and a spectacular explanation! Thank you.
Quality animation, quality modeling, quality information, quality voice, it doesn't get any better than this!
This video is one of the greatest things I've ever seen on the internet. I am grateful for having easy access to such a brilliant exposition.
With this quality of content and animations that you managed to produce, you could create a whole playlist on this field of computer graphics covering topics like Volumetrics,
Physics Simulations (Soft and Rigid bodies, Smoke, Fluid), Ray Marching, Metaballs, Ray-Geometry Intersections, Ambient Occlusion, Camera DOF and many more..
I think its by far the most interesting technological advancement in the history of computers and i am looking forward to more videos from this channel in the future.
This was incredible, not just in the information but the animation itself, which was probably a beast of a job for a GPU to handle. But some stuff finally clicked in my head on how the data was being processed.
This is not just a video. It's a completely class. A masterpiece.
Absolutely incredible video. In a world where many content creators are sharing worthless content on the internet, it is very much appreciable that you are creating and sharing such valuable content with that amount of work behind it. The explanations and animation make such a complex concept so much easier to understand and enjoyable. Thank you very much and please keep up.
one of the best explanatory videos of video graphics. Very intuitive and easy to understand. Thank you.
I've been in game dev for 17 years. This video is a must-watch for any game dev, veteran or new. I can't believe the quality of it. Well done.
have you worked on some major AAA games? If yes which ones?
@@IronMan-vh1yo Gears of War, Borderlands, Borderlands 2, Borderlands Pre-Sequel, Aliens: Colonial Marines, Spec Ops: The Line, Sunset Overdrive, Ratchet & Clank, and a lot of VR/AR stuff. I'm now out of the games industry but work with Lockheed Martin with realtime interactive experiences and pre-rendered cinematics.
@@steyrboy is it a hard job? Cuz I saw some videos where they said that there are alot of overtime work sometimes and stuff like that.
@@IronMan-vh1yo It all depends on where you get a job. Some companies strive to have good work/life balance while others run you into the dirt with crunching and overtime year-long. I chose my current company (Lockheed Martin) because of the job stability, and they will only ever make you crunch when something is desperately needed. The job itself is roughly the same between companies, software and team structures may be different but the core jobs themselves are the same(ish). I don't consider the job "hard", but you're always learning and trying to stay relevant with the newest/latest/greatest technology and ever changing platforms.
I am a GPU Hardware engineer, believe me this topic itself is vast and difficult to explain. But the way they modelled and explained, makes it easy and simple to understand. Great work
For me it’s the other way round. The video makes it seem way too complex.
What's your favourite GPU?
Geez man… this 20mins video and details in it would take me months to finish… amazing job, im speechless
Love this channel and the level of detail in the content combined with crispy explanations
Man you have no idea how happy I am seeing this video. Been wondering this for over 10 years, never got the time to actually look into the details about how rendering works. Even tried to learn blender and gave up because I have no idea what all the shading is all about. And in the last 15 minute I got it all figured out from your video !! 1 million thanks!!!👍
Same here! I've always been curious but never dove into it! Loved this video
This channel, PowerCert Animated, Veritasium, and VSauce just don’t know how to stop with good educative content, much appreciated
He was one of them? REALLY?!!!
Veritasium and vsauce's editor? I can't believe that... Is it true?
I don't think so I think he ment they all produce amazing educational content@@user-zp5xt8em6l
Hey, I really like ur videos! I hope u guys can discuss the advanced topics even further! Learning this has been very enjoyable.
such an interesting video! thanks for putting in so much effort for this 👍 Definitely going to be watching more from you guys.
Extremely informative video and its incredible that this is free to watch on UA-cam. Your work is not unrecognized. Thank you for this.
As an engineer I learned form many books / articles and was always sceptical about video learning. This one changed my thinking and I just realized how wrong I was ignoring UA-cam for learning stuff. This is one of the best prepared videos I have ever seen. Great job!
Yes please, I would love to know more on all these topics! Great information to help me understand these concepts (FINALLY)
Guys thanks so much for this video! I'm studying the graphics pipeline!! Please still working on more videos of computer graphics!! Love and greetings from Colombia!
This is extremely well made! The balance between simplification and completeness while keeping this as short as possible must have been a nightmare!
Hats off to you ladies and gentlemen!
I hope this channel reaches 10 million! Because this level of quality is so unreal! Especially with this content being served freely to the public!
It's an education channel. These kinds of channels almost never reach into high millions. This channel has been running since 2018 and only has around 50 million views. Most top non-educational channels get that number of views from one video alone and they post weekly. So no, wish all you want for this channel to reach 10 million subscribers, but it's not going to happen for decades. That's reality.
@@SnoopyDoofie that's fun, though I might give an example. Kurzgesagt, despite them shifting their priorities, they're still predominantly an education channel and is in the double-digit millions.
@@NiffirgkcaJ Kurzgesagt is mostly an entertainment channel for the masses. They dumb down the details. If they published a video with the high degree of technical depth that this video has, they would lose a lot of subscribers. I doubt that there is a single channel on UA-cam with 10 million subscribers that has the level of detail that this channel has.
@@SnoopyDoofie I'm quite aware of that, and I also know that this is just wishful thinking. However, I don't think that it's wrong to hope and wish that people care more for quality knowledge than the stupid things that became mainstream right now.
Your videos are amazing!! I can't imagine how hard it's to make. Congrats for the awesome work!!
If want to understand what your graphics card does and how it does it, to wanting to understand what the graphics settings do in your games menu. This is a great video, its really well put together and was easy to follow and understand.
Wow I am absolutely blown away, I’ve always wondered how 1s, and 0s turns into the worlds we get to explore today. I couldn’t help but think about the millions upon billions of calculations that go on every millisecond as you continued to discuss everything that goes into making a game look beautiful. I have nothing but respect for all of the mathematical genius’s that worked to help us get to where we’re an are today. Truly outstanding. We’ve made so much progress in such little time.
I'm a graphic programming students, and I have to say the most insane thing is not the millions of calculations, it's the amount of work and technique required for it to ONLY be millions of calculations, plus there are so many thing appart from that. For exemple the highly parrallel speed of GPU come at the cost of the speed of the memory access, and that's basicly one of the main limiter in graphic application. There are a lot of other things going one, and that video covered the basics very well.
Progress in computing has been so incredible to witness and live through. Playing my first 3D video game was mind blowing. I remember when people were just starting starting to have home PC's. Its incredible how complex it all has become.
I love this channel, it explains very well the concepts to understand the topics with the rendered illustrations.
This is really in depth, nice job! I’ve been in Game Dev for 26 years - worked on Red Dead 2, this was great. Hopefully accurate, I don’t code but use all of the art tools. Yes, please make a video on the art process! Would be cool to see the evolution of tools and process from custom late 90s game engines up to engines like UE5. Don’t forget how things are about to really change with Ai! ✌🏼
It’s wild that the same technology we created to compute triangles is soon to have created an entirely new graphics paradigm (and potentially a new life form at some point).
you worked on RDR2? Are you on the GTA VI team also?
@@sub-jec-tiv I totally agree, I watched the tech evolve from a few hundred polys on say an N64, to millions today. But like you say, the paradigm shift is happening. We are about to enter pixel level, procedural generated, model trained insanity. Its going to be nuts!!
@@DrewMedinaWhat do you think about that new leak
Worked on rdr2? Give me some gta 6 news
As a game designer this video explains perfectly the basics of how it works. I learned about most of this stuff by trial and error and reading documentation in unity and unreal. I think normal mapping and uv's are super difficult for some people to get their heads around so please please make a video on that. Explaining how it works in engine would be so good
You're done amazing amount of work in this video, thank you!
Hands down one of the most educative videos i have ever seen. The ability to take such advanced knowledge and make it understandable to the commoner is quite literally how humanity progresses as a whole. You guys are champions.
I'm dumbfounded, how could I miss this channel for so long? This is not just the best intro into how GPUs work, it's one of the best explainer vids about computer topics I've ever seeen.
This is hands down the best explanation of how video games are rendered. Instead of trying to explain it to people, I'll just have them watch this instead. It's explained simply with just enough detail and complexity to get a very good understanding of how it all works without completely losing everyone during the explanation. And I'm also so glad that you guys are going to make separate videos explaining raytracing and DLSS, and I'm also excited for a video explaining shadows, reflection, UVs, and normal maps!
That was a fantastic video and I hope you keep going deeper into this topic.
It's really cool how rendering,shading work on 3d, especially when i see those lines and vertex on the locomotive train. And Thank you for explaining it really well
I'm just amazed at how the minds of hundreds/thousands of engineers, mathematicians, programmers, etc. put together all of these throughout the years so that we can see what we're seeing now in our displays and monitors.
I've been doing CG for over 30 years now. I know how much work went into this. Educational and beautiful. Congratulations, great work.
I'm interested in all of the topics mentioned at the end of the video. Thanks for making beautiful, interesting, and informative videos!
This is a realllly good video and it explained the whole topic very well, thank you :)
Im a graphics programmer and currently write my own path tracer, and I must say, this video was on point. I would've loved more talk about ray tracing or path tracing, but I like that you and your team have explained rasterization very nicely.
Definitely on point and I second that sentiment about more on ray and path tracing
Might be it's own video
They said ray tracing would be getting its own video
@@alpsalishlet the number of hours taken to create this video to sink in kids 😂
honestly this series is not "one of the most educational" series I have ever watched on the internet, but this is "THE BEST most educational" technical series I have ever seen or heard, not just because of the informative content but the visuals, the pacing, the details and what not ... I'm at loss of words here. Kudos.
This is an amazing explanation and very detailed. Great work!
These retro encabulators are just getting more and more complex every day!
Awesome video!
this is the type of quality content a person should expect from a visual lecture. hats off to you guys for creating such detailed video!!
I usually don't leave comment even if I love the content, but this video is actually an insane work and I want to thank you for making this masterpiece. As a game programming student who love to learn how everything works, this video is from far the most clear and clean explaination of a so much complex concept. This introduced me to a thing I always wanted to dig in but was hard to know where to begin and find a good courses.
Thank you, really
This video is really blowing up my mind. I would love to see other videos like this to explain video games technologies in general.
Great learning video, please continue to explore more details, like DLSS and Ray tracing
When games were 8-bit and 16-bit my mind could understand basically how they worked, you could see each pixel and it was just a matter of sprites, backgrounds, and collisions, etc. Then we got basic 3D polygons, then we got more advanced lighting and shadows. Now game graphics are so beyond pixels and sprites, it's amazing how complex all the individual steps are in rendering a single scene. Excellent breakdown and detailed explanations, great video.
The fact that you've put this masterpiece for the world to watch for free is admirable, you're a true giver, keep going 😊
Very well explained, thank you very much!
And great graphics in this video also!!
Incredible video, I hope everyone who worked on this feels proud
It's just so incredible how freaking powerful these things are and what we're able to do. Every time I think about this kind of stuff, I'm amazed again. It feels a bit surreal.
I felt that way when I was first learning about computers and that feeling is still here 30 years later.
Yet people cry about graphics all the time instead of realizing how much work was already done for that effort.....
Amazing visualization and explaining! Over the past 5 years I have implemented a rendering engine completely from scratch in OpenCL; the coordinate transformation, rasterizatiom, shading, z-buffer, and even raytracing. This is beautifully summarized and explained in your short video!
