I Made a 3D Engine in 1 Day (WebGL/JavaScript)

Please, make a tutorial teaching how to make a 3D Game Engine in Javascript

Writtng a hole 2d engine right now

thoughts on batch rendering

No Use of C++

i remember playing a lot of games when i was young, but now its such a big pleasue to write my own games and 3d software, so i havnt even played a game besides my own (for testing purpose) since about 3 years. For that said, of course i got an quite good pc (70% percent on userbenchmark-desktop *planing to buy a good gpu for rendering though), but just need that thing for writing software and computing data xD xD xD all i need is frkn computer and internet!! its all that i need in life!

;)

this is great little project right here. For me the most challenging in 3d webgl engine is to manage cache, i guess you didn't bother here but with more complex scenes it is a must have (and three.js does this too), but the knowledge behind all the caches is a black magic for me.

Have you thought about trying to write all the different major renderers used in games? forward, deferred + forward, forward +, deferred + and forward +? (aka clustered deferred/forward)

I have written a similar simple WebGL Renderer, displaying a bunch of models loaded from a custom modelformat. This was the first and last time I write that low level on an engine. Just to have it done once. But I rather continue using a premade game engine, and leave that low level stuff to engine engineers.

My hero.
Instant sub.

I want to thank you about your videos. You really inspire me to learn three js and go more deep into data structures. Greetings from Argentina!
Keep doing this!

Why are you sending the individual components of the objects (colors, uvs, and positions) as seperate VBOs? Writing to the GPU is relatively slow, wouldn't it be logical to just use a single VBO, and use a VAO to specifically layout the vertex data?
In C: glVertexAttribPointer() would suffice

I feel really uncomfortable looking at a 1200 line long javascript file.

Only programmers with IT and math background will understand.

There's programmers, and there's elite programmers. This guy is part of the elite club, without a doubt. Decades of practice is evident. Absolutely fantastic to see. I don't know whether to be inspired or hopeless. Lol

Great video!
Did you work on Prototype, by chance? There was a Prototype clip that played when you mentioned you used to do game dev, and now I'm curious as to what you worked on.

In all my nearly 40 years of coding I've never gone down the graphics path. A lot of this went over my head but it looked very impressive!

"...I was also drinking beer at this point...." <- midnight coding. :D

I did it in a min 😏

do you can make 3d minecraft with your 3d engine?

framebuffer incomplete means that the framebuffer is incomplete.

Code not working

From Canada? Worked for Ubisoft? No British accent and the way you spell “colour”. ;)

I love your videos even though I have no idea what is going on except at a very high level

Man ... I had no idea JS is able to do this....

Love these videos man.

Usually there is no point in making own engine and loose time you could spend already on coding something in existing engine.

Why in some of your const you write C++ code?

Your voice is tad similar to Bisqwit's

Professor Simon, I've been studying your material with a few colleagues and we were wondering how heavy was your program's size. We all found the video fascinating!

That was freaking incredible!! Thank you so much!

The fact that you do everything in one file, makes me feel uncomfortable... But it works.
So I'm just trying to not bother - Three.js is killing it and now WebGL 😂

Love your videos!

Hey, what's the deal with underscores at the start of almost all variables names? Just curious.

amazing content from an experienced graphics dev is rare

This mans voice is so soothing for some reason... I don't get everything he says, but I could listen to him for hours.....

Amazing as always (. ❛ ᴗ ❛.) love from Belgium

What games have you made??

We made one of these in college, was pretty cool actually programming graphics... and by cool I mean horrifying.

Wow amazing, should I move to js 🥴

Float textures have only been around for like 15 years. So of course make them an extension. I lol'd.

I made a calculator in 1 Day (Javascript)

Very cool, I use 3js and it would be nice if there's a better/optimized option out there maybe something that's better than webgl

I feel that I need coffee before finishing this video

Thanks for your info sharing. What do you think about the future of webGL? is it still worth learning? Thanks.

Sweet...

You can feel that this mean KNOWS alot of things and its SOOO cool to see him enjoying the new technology
as he stated in one of his videos - C is complicated AF and unneccesary much lines of codes

there he goes with JS and creates awesome stuff with nearly no effort

I don’t know if you have much experience with it but debugging memory/webgl/performance with the chrome debug tools would be another interesting one

Those tools are an art
