hello

DON'T FOLLOW WHAT VPNS SAY TO YOU!

make a good game

Nah that’d be too slow and error prone, he’s gotta write his own language and compiler, this way it’s much faster than writing machine code when he starts the project

@@jrgerba thats why its a joke.

give me a few months

omg!

He’s gotta build the monitor this all displays on

then, on a fling, he will decide to spark electricity through some carbon based matter to create organic soup which eventually evolves to a cow

Sus

@@not_herobrine3752 good soup

ye, but he did not even mine his own silica for his computer, and now even use a proper programming language instead of going to the better way of writing his own os for the minecraft he wants to build later.

even if it is little dump, I still like it

It's actually a fun (for nerds like me, at least) hobby, seeing how it's essentially creating viewable and interactable universes using only math and the power of computers. And the linear algebra and trigonometry involved can be learned without too big of a problem even by not very great or educated mathematicians like me (thank you 3blue1brown for teaching me more than my entire highschool did); and it's a mind-blowing experience itself, combining many "I will never, ever use this IRL" concepts into a practical, working whole.

@@DeuxisWasTaken I tried using a 2d engine to do 3d and gave up after suffering math

I have to agree with @The Crazy Pineapple making engines is fun. I even make videos about it. But anything 3D graphics related is pretty interesting for me :)

This is extremely far from scratch considering how much bgfx does for him... :)

You should check ThinMatrix’s Equilinox series… be amazed 😊

lol yeah

c++ is the best

C++ is such a weird beast since the standard is so big and complicated that you can really just pick a style and write code in it, whether it be "C with classes" or "C# but I pretend to be cool." Then you read code written by other people and suffer greatly

@@Catonator I feel like "C# but I pretend to be cool" is someone I know. I'm not sure who, but I must know someone that does this

@@Catonator Apologize for the stupid question, but what makes C# not cool? Is it just it being easier, or what?

It's for combatabity

while this is a valid point lets pretend that it's for easy cross compatibility with all platforms because the old one didn't run on windows and used openGL (vulkan better fight me)

@@universallyepicnarwhal9102 I'm sure you could get it compiled on windows pretty easily. I was referring to cross-compatability between graphical api's...

jdh in a parallel universe: writing my own rendering library in assembly

Cut him some slack , even 2 years ago he used a rendering library

That’s actually due to depth map resolution :) I should have cranked it up to 8192x8192 for the shots in the video - but IIRC there is already slope-scale depth biasing in the lighting shader!

I like your funny words magic man

​@@__8120 AHHAHAHAHA

@@jdh probably you can just grow the shadowed part a pixel or two (I mean adding to the border)

Looks like you're casting from back faces, not front faces? Otherwise, yeah, you need shadow cascades for an open world. Which sucks.

i agree. he could also implement a drivable truck so he can hit the glowing... well you know.

@@nikkiofthevalley A language designed for an OS from god, implemented by someone with schizophrenia.

@@abbanf hey, the dude wrote a compiler, don't do him like that

@@user-qp3qj2jv6f so what? Writing a compiler is definitely not an impossible task, people do that all the time in unis

Great idea please do this

@OrangeDied Roblox pfp?

@@longiusaescius2537 yes

@@OrangeDied nice, Napoleonic wars are very aesthetic

I agree so much! He should definitely find the time to explain what he likes of libraries and how he has written this code!

Me too !!

jdh doesn't seem to be the type of person that knows how to teach what he knows. That's a skill separate from the knowledge you have.

Professional Rust shill here, and I'm also curious why he dislikes the language. I do agree it was probably a good choice to avoid it here though, given the game-dev scene is still so-so in Rust.

@@zombie_pigdragon Rly ? Look at Tantan he's using rust (bevy) for some of his projects and it seems like it's working. I have never heard someone complain about rust being used in a game. Like the language a game is done in shouldn't really matter. The only thing that matters is if it's a good game or not.

@@sutsuj6437 Of course it's possible- I've been keeping an eye on it, though I left that out of my first comment. Right now, I'd even argue that if you're willing to put in work at a similar level to this video, everything is available, sans examples. But those examples are a key part- with finished products comes learning tools, and features and ergonomics. The Rust gamedev scene doesn't have that yet, and it'll be years before it can catch up to C++. I'm sure it's possible today (and in fact, I hope someone will) to recreate this video with wgpu and patience, but it'll still show more rough edges than C++ for a while longer.

@@zombie_pigdragon As someone who tried rust for games... Yeah sadly it's not that great for games. Still use it for literally everything else though.

@Zombie_Pigdragon would rust have better performance if it had those things?

lol " *an* java programmer" Almost missed the joke

@@ilmalocchio i didn't get it :(

@@semihkaplan Yeah I guess the "an" was just a typo and there is no further joke here.

@@dasKeks28 yeah i guess

@@dasKeks28 not a typo, n oway. Try to type "a" right now and consider how bad your finger would have to slip to type "an" instead. It's a very nuanced joke. He's calling himself stupid, and he gave us a hint of evidence for it (bad grammar)

Yeah it's a bit odd I also think it must give a special unique charming vibe to the game after some time though (think of all of Minecraft's quirks that we just got to enjoy haha)

You worked on minecraft?

hey wait a minute why is there a video with over s million views on your channel

Oscar Åkesson? didn't your brother also do something?

U worked on minecraft, mr minecraft dev?

Yes, I work at Mojang currently, no I dont have a brother :^) edit and because I was immature and basically ignored dcma as that wasnt really a thing when I was too young to understand stuff

The features in C++20 can be pretty amazing, but it's a shame that they're still crudely bolted on top of the "old" C++ which was crudely bolted on top of C. The features might be "modern" (whatever that means), but C++ is not modern and never will be unless the entire world suddenly starts writing C++20 overnight and all known and maintained code magically transforms as well. Tons of professional C++ developers still write C++ like it's 1998. And tons of actively maintained code is still written in that style as well. And onboarding devs to this new style is not easy either, as it's hard to deny that with all those cool features there has also been an explosion in complexity in an already complex language.

@@robinmattheussen2395 I agree 100%. That's why I started avoiding working with C++. It's my favorite language if I'm working alone or with a team where everyone thinks like me. But I've been in teams where one guy wants to write C, another guy wants to slap virtual everywhere and a third guy is randomly mashing the keyboard but somehow it compiles and no one can refactor it now.

I wouldn't say I hate it (I used to do a lot of projects with Unity) but for my specific use case it just does the job worse than other languages. If you want a garbage collected language take Go, if you want an easy to use take Python, if you want speed C++ or Rust, etc

Eh, I don't even hate it - I've used it at a few jobs full time even. My primary gripe is actually the same as C++: the language feels really bloated. Especially comparing with something like Java, it feels like (imo) there's a lot more you need to keep in your head while you're using it.

@@jdh Java, C, C++, C#... How many languages do you know, if I may ask?

@@achille0072 "know" is a really strong word for any language 😄 I'm familiar with a lot of different ones (like touched on/messed around with/done projects in more than I would care to list or could probably remember) but most comfortable in Java and C

Its basically just Java, but less original

Yeah i got the notification instantly

Happy 2024

I suppose he just came up with a quick solution by blurring all of the edges of the shadows to a lighter color, hence a bright line at the start of the shadow right next to the cube.

It is an artifact/bug from the shadows. To fix it JDH just needs to render everything front and back without any backface culling when creating the shadows maps. There is a full explanation in the comments of the learnopengl article mentioned in the video.

Yeah, this bug kinda negates all the work he put into implementing ambient occlusion.

C# has unsafe blocks. You don't have to let the CLR do everything if you don't want to.

@@BrunodeSouzaLino correct, but not as open as using Unity Burst for C# :3 - tho new core 6 comes close!

There are RISC-V and FPGAs for that to help

He said he didn’t like Java, and c# has a garbage collector which ig he doesnt like

My biggest issue is just language bloat tbh - if you're going to work in that sort of world of managed code, Java is at least a lot easier to keep in your head than C# I think. The language just feels like a bit more of a mess imo

@@tommy4808 I do actually like Java a lot, it's probably the language I'm the most familiar with out of any - and 99.99999% of the time the garbage collector is fine - but for this project it comes down to portability (meaning not Java ☹), performance, and ease of adoption (meaning not C#) for me

@@jdh What do you mean by bloat? Do you have some examples?

@@jdh epic

that would be sick

Same but with a triangle instead. Literally the first thing you do in opengl tutorials.

Try Vulkan mate. 1000× more debuggable.

@@shambhav9534 I believe the boilerplate though will be intimidating for beginners. That's why it's always recommended to start with opengl.

@@syedahkam7164 I don't think beginners who can't code a thousand line boilerplate should even start doing graphics.

@@shambhav9534 Thats reasonable

same it's both low-level and high-level on the same time, depending on how you want to use it

How do you find a Rust dev? Pretty easy, they’ll tell you.

HI

Hello first comment!

That's not really what is happening here, shadow mapping is wildly different from any sort of ray tracing.

Also, not even true with most real time ray tracing. Those calculate each "bounce" forward from the light.

@@SimonBuchanNz Do they though? I thought the typical raytracing method is to trace a ray from each pixel of the camera (presumably from the near plane) because otherwise the vast majority of the light rays never hit the camera and are wasted effort.

@@clonkex it's a bit messier than that, since you need to take lots of samples per pixel per bounce, and lots of bounces per sample to get a convincing image, so the naive, brute force approach lots of offline renderers use isn't feasible. Different RT GI implementations have different specifics for working around this, but they all generally amount to persisting the amount of light in the world at each point and then iterating on bouncing it around, which has the effect of flowing the light from the source around the scene before it reaches the camera. That said, the actual form of the persisted world lighting is very heavily camera influenced (to the point of being screen space for Q2RTX), so yeah, not a nice clean answer. RT shadows might be pretty much tracing in reverse, but I don't know if I quite count a single bounce as having any direction?

Lol so true
