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 KZbin 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.

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.

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!

[@MsGrowland]

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.

[@DidrikNordstrom]

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.

[@julianxe]

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.

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.

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.

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.

[@flippert0]

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.

[@FanDelfinDelMundo]

This is fascinating. Wonderful work by whoever owns this channel. Thank you very much 👍🏽

[@marnkleinholkenborg5852]

One of the best video's I have seen on KZbin, very well done!

[@jfraserm]

I've been doing CG for over 30 years now. I know how much work went into this. Educational and beautiful. Congratulations, great work.

[@aloktripathi27]

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.

[@coIpan]

Definetely incredible work! Thanks

[@aalasady]

This is amazing work guys, learned so much!

[@dexterian477]

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!

[@DrewMedina]

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! ✌🏼

[@sub-jec-tiv]

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).

[@mahavakyas002]

you worked on RDR2? Are you on the GTA VI team also?

[@DrewMedina]

@@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!!

[@glungusgongus]

​@@DrewMedinaWhat do you think about that new leak

[@goku614209]

Worked on rdr2? Give me some gta 6 news

[@synerdjin]

This channel provides the best visualization accompanied with deep but eloquent explanations. Absolutely love your work, folks!

[@hellosonymoto]

Very good job. A nice video that explains a complex thing in an accurate and easy to understand way. Thank you.

[@NoNameyt2004]

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!!

[@FreedomRoseStein]

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

[@matthewtaylor8394]

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.

[@gaetanlang8869]

This video is just incredible! Thank you for your work

[@HarmonicWave]

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.

[@ridid]

Extremely informative video and its incredible that this is free to watch on KZbin. Your work is not unrecognized. Thank you for this.

[@rokelbow]

Amazingly excellent work. Thank you for leveling up my knowledge. ❤

[@tupacca5136]

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

[@top.of.reddit]

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.

[@WadeMorrisZA]

Definitely on point and I second that sentiment about more on ray and path tracing

[@alpsalish]

Might be it's own video

[@apollobukowski4275]

They said ray tracing would be getting its own video

[@rayfighter]

​@@alpsalishlet the number of hours taken to create this video to sink in kids 😂

[@parthpurani514]

The fact that you've put this masterpiece for the world to watch for free is admirable, you're a true giver, keep going 😊

[@Serutans]

Incredible video, thanks for your work!

[@user-kt5xw5cx2l]

Amazing! So deep in the topic and so good processed for learning

[@eliott8275]

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

[@briancook6875]

such an interesting video! thanks for putting in so much effort for this 👍 Definitely going to be watching more from you guys.

[@unstbl6140]

Incredible work, thank you ❤

[@ProjectPhysX]

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!

[@goncalomonteiro8314]

I cannot recall one single video I watched as well made and produced as this one. Absolute masterpiece.

[@LiamDennehy]

This video is PHENOMENAL! The work put in really shows, what a great result. ❤

[@ihorzaika1412]

Awesome explanational video! Mega job!
