I tried learning OpenGL in 7 days - using Rust

[@PolyMars]

this is so cool! graphics programming is magic

[@fdevstudio5692]

You have sdl

[@LoganStringer]

The way you code "out loud" is hilarious and is how I talk to myself internally when I code... But with more cussing. Great video!

[@Tantandev]

haha "but with more cussing"

[@LucyPero]

That's so awesome. I was just about to use macroquad for my game and resume learning Vulkan in Rust haha. You are so prolific!

[@Tantandev]

Haha what a coincidence!

[@dimaspadma8073]

why you prefer to use vulkan instead of opengl?

[@ThisIsAnAccount]

I am genuinely disappointed that I haven't found your channel earlier. This was a great video. I'm glad you addressed the ups and downs of learning graphics programming and actually showed your progress. I remember learning shaders and OpenGL for the first time and getting used to it over many months. It was agony, but damn.. the satisfaction is unreal when you get something to work AND actually understand what and why. Top quality video, plus Swedish accent automatically adds a +10 enjoyment buff. Now to watch all the other stuff on your channel!

[@GrizzliusMaximus]

I love graphics programming! once you start, you will realize how much you have been missing out. The endless possibility of Graphics programming + how it utilizes the GPU. Can't wait to see the premier! edit: just watched. great video as always. Love to see you getting better!

[@j_respect5948]

I dont know about that.... I feel like i become nothing and can't learn anything..... Everything seems impossible

[@abuazzan462]

any advice on how to start and what language i should begin with?

[@not_herobrine3752]

the day that happens is when i manage to link a goddamn graphics library in windows, and that will happen when pigs fly

[@WannibeManisha]

Looks amazing and really natural!! I'm still intimidated by shaders but someday I will tackle it! Always enjoy seeing these small challenges 😄

[@ThatOneHandsomeGamer]

Finally! There's a severe shortage of Rust opengl videos on KZbin

[@LoganStringer]

Right?!

[@GrizzliusMaximus]

not a rust user but man, Tantan surely is convincing me to be one!

[@thedeathchimera]

This video got me into Rust, and now I'm learning it through the free Pluralsight event going on. Actually feel like I'm making programming progress. Just gotta push myself through the glsl tutorials.

[@TheSulross]

huh? I thought this was a video on a dude trying to learn to play a weird musical i strument

[@hanes2]

the lack of Vulkan and Metal is even stronger.

[@Skeffles]

Great water shader! I've never really gotten on with shader code so it's great to see you making such a neat effect.

[@aliancemd]

That looks so good. It could also be used for the fire effect, representing the hot air/heat distortion.

[@Tantandev]

Good idea! I definitely should tweak it a bit more so it's a bit more watery looking

[@ankitnautiyal2568]

Wow great work. Thanks thanks thanks for trying these cool things out, its really inspiring. Also you are really doing a great job for rust and game dev learners.

[@SmoothieBuns]

That water scene looks a lot like a maplestory scene... i love it!!

[@guogeorge7956]

Actually I am more intristed in how he made the wrong refletion at the beginning.

[@woodmanmade]

Love using "side quest" to describe when you get distracted by a shiny object and spend WAY too much time not working on what you originally planned 😅

[@Tantandev]

haha yeah!

[@theburntcrumpet8371]

You have good taste, we have the same monitors and audio interface

[@timothyvandyke9511]

gotta say those graphics and that water shader make me want to play that game

[@algs5483]

3:32 I love this sound. Reminds me of the COWS.

[@FlashBreakerOfficial]

here a small deform shader^^ f = 0.5 ; // factor or intense nm = tex2d(normalmap, vec2( x + time, y )) ; // move in time nm = saturate((nm -0.5 ) * 2 ) *f ; // saturate make the value is betwen 0 ~1, and the -0.5 and * 2 is to scale the map from middle point result= tex2d(render_tex, vec2( x + nm.x , y + nm.y)) // deform render textur with normalmap ^^

[@KropedStudio]

most sane rust programmer

[@qxb348]

This channel is golden!

[@JesusMartinez-zu3xl]

You give me confidence in learning open gl!

[@DestroManiak]

one nice idea might be to slowly reduce distortion of the way as you get closer to the boundary of water

[@KindStarWonder]

Love it!

[@PeterFaria]

I hope you’ve looked at writing shaders as separate files. There are vscode plugins to allow syntax highlighting for shaders.

[@rustmc]

so hyped, wgpu next time?

[@Tantandev]

Oh wow, wgpu looks awesome! Researching what it was I came across this tutorial: sotrh.github.io/learn-wgpu/beginner/tutorial3-pipeline/#vertex-fragment-what-are-those My interest has peaked!

[@abhinavkuruvilajoseph9274]

wgpu seems interesting but it does not support older hardware :(

[@rustmc]

@@abhinavkuruvilajoseph9274 they do have an opengl backend, although it is apparently is still WIP

[@abhinavkuruvilajoseph9274]

@@rustmc yes i saw that. till then i cant support older hardware if i use wgpu

[@rustmc]

​@@abhinavkuruvilajoseph9274 true, but overall you can still support way more systems with wgpu, heck even the web

[@half_invisible]

cargo fmt commit instead of hooks is such a mood

[@_RafaelKr]

6:56 this Ben Böhmer Set on the Cercle KZbin channel is just amazing!

[@Tantandev]

Yes! I listen to it a lot when programming, good eyes!

[@_RafaelKr]

@@Tantandev If you like this type of music for programming I can really recommend the set of Mark Tarmonea on the channel "Vibrancy Music". Very good vibes! :)

[@falxie_]

I looked up Rust game stuff and wasn't disappointed

[@estanforth6754]

Vulkan next!

[@LunaCoco]

Oh, hype

[@brotkopf169]

"I've gone through the complete tutorial, so that is a course for celebration" **blows the horn**

[@LaChips806]

You can actually create an OBJ parser pretty easily. It's a simple file format. I've been able to do in in a few minutes. Rendering however, is a different story..

[@andrewjohnson1835]

17 more hours to goooooooooo

[@enkelenahaxhiu3705]

fun content!

[@adytm]

Cool vid Good luck

[@xbz24]

[@roucool1323]

Nice video!

[@coffeecatrailway]

This reminded me I have a lwjgl side project...

[@koldovalnya]

I MUST subscibe at least because of THIS xD: 3:33 You are the best dude :D

[@ypaut]

I swear

[@pislify34]

rust and opengl looks like that kind of thing that looks forbidden by the C gods

[@ninocraft1]

nice, thx i will steal that xD

[@ferdinand.keller]

Nice we can agree on rust being the best

[@blackmirror9573]

good work... i really like it....

[@vectoralphaSec]

Is there a possibility that Rust becomes just as used as C++ in the games industry for game development?

[@Tantandev]

I truly believe so, but what we have to see then is probably more game engines being written with it. I could see Bevy having a big impact in the future.

[@costelinha1867]

I mean, I doubt most game devs will use it for scripting, as they'd prefer a simpler language, but I can totally see Rust being used to power future game engines, making them safer and all.

[@zed4314]

Man why are swedish people so damn good at KZbin

[@filippocozzi2941]

What tutorial did you follow? Also great work, i can't imagine how hard it is to learn something completely new in such a short time...

[@Tantandev]

sorry for the late answer, I followed the "glium book" it's in the official glium repository: github.com/glium/glium/blob/master/book/SUMMARY.md

[@coolmanthecool603]

Now do it with vulkan

[@LucyPero]

I wish I could learn Vulkan in 7 days... it's gonna be tough 😓

[@Tantandev]

That sounds very hard! :P

[@qops1981]

Maybe you already have by more, but you should try the newer Vulcan API. I think even OpenGL supports it as a successor.

[@SuperCacazinho]

You look so happy

[@AdhirRamjiawan]

epic video!

[@costelinha1867]

Aaah Rust, the language with a compiler so strict that it made me run away to C in fear, lol.

[@julienblanchon6082]

I'm strugling to learn opengl for doing some gaussian splatting stuff it's quite hard

[@jawtaro4583]

reminds me of the game, Kingdom

[@Byynx]

Is it possible to have your text editor color layout ?

[@CreateDefaultSubobject]

Does intellisense work well in visual studio code for rust?

[@costelinha1867]

Yes, provided you're willing to wait for the colossal time it takes for rust_analyser to load.

[@passivecryptoearnings3605]

Please write your shaders in separated files !!

[@ajinkyax]

I started learning C++ and Dx11 (since C++ has way more tutorials) I used to make games in Rust and Bevy. What will you suggest me ? Since I started Bevy cause of your videos :) So far what I like in C++ wish Rust had, a better IDE support visual studio, Rust analyzer always fails on me, I had to change 3 OS so far to get it working. C++ has better documentations, Rust has the book which is the best thing, but lacks in Rust docs which I never understood.

[@bhuwansharmaa]

I stopped at the triangle :( .. need to start again

[@Tantandev]

it truly takes a long time to wrap your mind around how everything works together. I'm now doing round 5 or six of making a graphics program from scratch. I'll have video on it later :)

[@bhuwansharmaa]

Yeah its like iterative process of learning. Get the blurry picture in mind and then sharpen it up with repetitions

[@spodarman3823]

How is his accent so confusing and so clear at the same time

[@bojantanasic221]

Rust is more convenient on linux to install in order to make it work. In windows I need to download visual studio and install some components from the workload. I haven't used it in a while but what made you choose rust over c++?

[@ahmadj1064]

programming on *nix is better in general

[@Temulgeh]

i find it funny that working with the API didn't seem that much of a problem for you, but GLSL was, because for me GLSL was the break after all the API nonsense. Maybe the wrapper you're using is just that good

[@RoboticusMusic]

What could I do better in Rust than anywhere else?

[@comradepeter87]

Nothing better or necessarily faster (unless you're not talking about C/C++), just safer and more elegant.

[@wait...6531]

I'm trying to learn and man it's hard

[@Tantandev]

Yes it is, it's like learning a new programming language almost, so many concepts to grasp!

[@zaleyu5275]

Beautiful keyboard. Is that g915? Thanks

[@Tantandev]

It's a keyboard from a company called Wooting. They keys are analogue meaning it knows how far in you press the keys, pretty cool but I don't use that feature really... My first mechanical keyboard :)

[@zaleyu5275]

@@Tantandev thanks, it’s pretty

[@uotsabchakma]

Oh thanks! For what? For letting me know that there's a graphics crate named glium!

[@panjak323]

OGL is pain by itself. But doing it in Rust ? Suicide.

[@gsbenassi1735]

I have a question: This type of function is ONLY for the aesthetic use of maps where the player does not use water (in other words: if he falls into the water he dies) OR is it possible to program this function in games where the character falls into the water and can swim and sink in it? Because I can't imagine a characters transition going down, obviously in a single "tale" Since I know that this function only serves to represent the surface reflection. I ask this because I intend to introduce maps where there is a transition between surface and water plane, and I think it would be difficult to use this function in a game like this, where you can fall and swim 🤔

[@uljonata3947]

can u make a game with vulkano-rs/vulkano in 7 days?

It has been more than 7 days, I still can't setup OpenGL properly.

[@itay2826]

I'm not going to lie.. I'm probably the most lazy man I know but I want to start learning to code (I don't know any Programming language except really really noob level py but I'm 14 so I guess it's not soooo bad Situation) and I don't know if should I start with py, java, js, any c (I know they are nothing alike) or rust and I will love to hear from you what do you think because when I starts something I'm putting my whole time to it.. so I want to be sure I started with the best (I knew that I need to know more than one language and that I have a lot of time to discover myself what language it's the best for Me but I want your advice as a very smart and experienced guy) so.. ?

[@Tantandev]

I don't think it should matter to much what language you start our with. Try to make many small projects. I got started with graphical programming using multi media fusion, but I would probably not recommend starting with that. But yeah over time, you are probably going to get to try out many languages. A valuable skill is to be able to find resources to learn, searching for tutorials, articles, videos. Find a language/game engine that you can find a lot of learning resources on

nvm jag märkte det sen senare i videon

[@tecnotrecos1680]

Now learn vulkan in 7 days

[@Tantandev]

Some day maybe :D Would actually be pretty interesting experience

[@danifeldman8884]

I have wondered at the beginning how you learned OpenGL in 7 days when youtube recommended me this video. So it is just a Rust graphics library, and you modified some examples, ok : )) Something like the Magnum C++ graphics library I use for a game but I guess you can set it up easier. It is ok to understand some basic math used in graphics and shader programming which is a whole new art and science on a lower level. But it is confusing to say that that you have learned openGL in 7 days.

[@macawls]

you are hilarious
