I didn't even think that 3D graphics without polygon rendering was actually a thing outside of abstract math visualisations

[@michaeljohn5130]

Dreams on the PS4 actually use this. It doesn't use any triangles but relies on primitive shapes and ray marching to create its models. I'm pretty sure it doesn't use image textures either. And it's outstanding the kind of games they made there Here's a Courage the cowardly dog game made in Dreams PS4: kzbin.info/www/bejne/mH2xZoOIetubaZosi=ourKPb55V4NGAYSO

[@invertexyz]

If we're being technical, it's still rendering polygons, 2 triangles that cover the screen, and then math to construct a world in those triangles! A lot of math for modern game rendering fakes detail on polygons, as a lesser extreme of what's done here. A prime example being parallax-occlusion mapping, which is like a normal/bump map that can actually occlude areas of itself (within the render bounds of the mesh triangles). resulting in the appearance of a physically modeled detailed surface but is just a few polygons.

[@nestorboy]

@@michaeljohn5130 I believe Dreams doesn't use ray marching for rendering, they do still use SDF primitives, but for point cloud cluster generation, and they use a splat-based rendering approach since the former failed to yield the artistic results the team desired. I can really recommend Alex Evans' Umbra Ignite 2015 talk "Learning From Failure", which is also on KZbin, where he goes over all the rendering techniques they implemented in order to tackle rendering a sparse set of SDFs.

I’ve done a lot of messing around with making 3d code front scratch, but seeing just how far you made it made me really respect your abilities. That’s not even mentioning how well you explained the concepts in your video too. I like to say that if a programmer tells another programmer about a thing they did and the other programmer goes “I could do that”, that doesn’t mean the first programmer didn’t do anything challenging, it means they did a good job of explaining it. This was a terrific video, and I predict your channel will continue to grow in size exponentially. Good job and thank you for the entertainment+inspiration! Edit: thanks for the 200 likes!

​​@@xseis. I agree... My brother-in-law went from making 3D the old way of shaping and stuff to mostly code to get the same result by generating it instead and it's mostly code and scrip with a damn lot of math... And he goes from buildings to rocks, trees, grass and everything all done that way and changing some values can sometimes generate a gazillion amount of different results without having to actually shape them all manually like the old way. 3D nowadays is more about procedural generated content than losing hours manually shaping stuff cause why would someone lose many countless hours shaping like hundreds of different trees when with code the same code just changing some values can give you that pretty fast after all the code is done properly... However they sound more simple than reality, they still require a lot of knowledge, it's not just pressing a button and it generates, it requires too many stuff that someone into old 3D of manually shaping if doesn't update them self will easily and quickly lose the spot. Edit: forgot to say he mostly uses Houdini nowadays, long goes his days of 3DS Max, Maya and many others... I just hope he starts using Unreal Engine 5 too some day cause if he compile the project at least I could try them 😎

Dang, this is so underrated. I was watching this and thinking: wow, this guy probably has a lot of subs. Got to the end of the video and was so confused. Then I was even more confused when I saw that you’re only at about 200 subs after posting this. This is pretty epic (albeit horrific that you just hardcoded everything, and it’s giving me ptsd from coding on khan academy), and it looks really good.

[@ggtooez]

This is very impressive, especially with pure ray marching! Though my main issue with the method is that you eventually need to draw a lot of different objects, and this will reduce the performance. Unless someone figured out how to use octtrees in shaders

I didn’t think that you could render 3D objects without blender or some other tool but it actually makes a lot of sense. These tools probably use a lot of hidden math behind them to create the scene, they do most of the thinking. It’s possible for you to do it with just code but extremely difficult.

[@BryceDixonDev]

As mind blowing as these techniques probably are for a lot of people, they used to be pretty common and its honestly a little disappointing that its taken this long for people to start rediscovering them. As a professional developer, it's frustrating when large AAA titles release which completely lack any kind of shader techniques outside of albedo and normal textures as though procedural textures (and even models) are artistically effective while remaining decently efficient with a low runtime and storage memory cost. So many low res, repeating textures could just be math and be better in nearly every way! I appreciate when people like you showcase that.

[@totalermist]

I was about to give a comprehensive and detailed answer at first, but decided to sum it up in a single sentence instead. There's technical and organisational reasons for that, the latter of which being the most impactful. It's all fine if you're a solo dev or have a tiny team (less than 10 people total, for example). Beyond that point tooling and education become a nightmare for big projects if you go down that path.

[@BryceDixonDev]

@@totalermist I'm in AAA, so I know there's definitely friction with larger teams - some more than others (*Microsoft*). Though I also think if there's a good argument to be made for procedural graphics it's pretty easy to get the team on board. Eg: "if we write a custom shader to generate brick textures, we can easily make a ton of unique variations and lower our overall art budget while increasing the fidelity of the art." I hate to harp on it because I feel like it gets enough negative attention, but the few latest Pokemon games are a great example of what I mean. Super low res simple, repeating textures being stretched to cover an entire wall or floor when just procedurally generating them would have been easier/faster to iterate and looked significantly better.

[@orionblackstorm7926]

The thing with using the CPU in games is the CPU (Central Processing Unit) does every single task bit by bit, it does not do one script at a time, it does one function, one singular thing at a time, doing all scripts slowly. Meaning if the CPU is overloaded with too much stuff, it slows down everything, not just one script but everything, while the GPU (Graphics Processing Unit) is designed to do thing related to graphics and can do so effectively without interfearing with anything else.
