(It takes like 200+ hours for one image to render, even with Carpet Mod which speeds up your game)
Some people in the comments said that what I built is actually a Pathtracer, Raycaster and one guy thought this was Raymarching.
I've had this discussion for years. Using the names introduced in the old original papers has become very confusing. Today, Raytracing is mostly used as a very general term, and both Pathtracing and Raycasting are listed as a subset.
e.g. Wikipedia's page about Raytracing: "...ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping and path tracing, ..."
Wikipedia's page about Raycasting: "..., see ray tracing (graphics) as both are essentially the same technique under different names. Scott Roth had invented the term "ray casting" before having heard of "ray tracing". "
Raymarching usually just means that the intersection is computed iteratively by stepping along the ray in small increments - I'm not doing that at all.
What I built is bascially a "Raycaster" - the most important part of a "typical" Raytracer, it shoots the primary rays into the scene. The problem with calling it raycasting is that today people associate that with something that is very different from what I built. e.g. If you search for "raycasting" on google images, you only find Wolfenstein 3D stuff, which is actually only casting rays in 2D, which are used to define the height of 2D collumns to give the illusion of a 3D environment.
What I built uses the exact same camera system as a typical Raytracer, but I do not shoot any further rays for reflections or shadows - I thought about rendering one sphere and a reflective floor plane - but that would not look good on a redstone lamp display. I need to build a better display first, that can display multiple shades of gray without dithering. I decided for rendering 8 spheres in a cube formation so that it can be compared well to rasterization.
The main motivation for me was to learn binary arithmetic, and building a simple programmable computer. And Minecraft Redstone is perfect for learning such things.
This build is actually not that complex, the only reason why nobody built a Raytracer before is that it's super slow and you can get better looking images with traditional 3d rendering (rasterization).
This was my first time actually using Redstone for something more complex than opening a door. A lot of things could be optimized... especially the individual components like the adder and multiplier are not synced so a lot of time is wasted in between instructions.

This is seriously amazing dude! The presentation and build is top notch, you deserve way more attention! I just watched your other videos and when I saw the blender nodes representation, I knew it would be a great fit for redstone because it instantly reminded me of how I draw redstone schematics, lol. I'm glad my tutorials could help, and I can't wait to see more!!

Could records in shulker boxes help compress and simplify the build? That is, each record outputs a specific signal strength and each shulker box can hold 27 records, so you could make larger transfers of data quickly and even create solution tables for instant calculations.

This is so amazing considering the complexity of ray-tracing. Less than 6 years ago the first real time RT silicon chips were rolling out of TSMC... Now this. Multiple layers of software and overhead and it renders an image in under a week, when dedicated RT hardware used to render some similar 20 years ago IRL.

Very interesting control scheme! It's not quite a processor in the traditional sense, it's more of like an application-specific circuit which probably makes it much faster. I wonder if you make some approximations or culling if you could get 3 or 4 bounces of the rays to do things like basic shadows and reflection in a reasonable amount of time.

[@fruittree1670]

incredible work mate! instead of using read stone lamps though, wouldn't it be possible to use command blocks to set pixels in a block display? not only could you render in colour, but the coloured rendering would make reflections work better if you ever chose to render more than one ray.

[@realoscar91]

yo this is super cool!

[@glitchreloaded1284]

Hey as a by the way, to my understanding of redstone you could speed the renderer by using things like rail instant wires and observers more than redstone dust as the signal(IIRC) going through dust is slower because it needs to send the signal through each piece of dust in sequence, if this isn't the case do let me know

[@cyborgbob1017]

It probably is but theres advantages to both

[@LunarcomplexMain]

Having a signal pass through the entire system while only needing to select which part of the ALU accepts this signal was a pretty good idea

[@randomsnow6510]

Like this so he can see: theres a mod called MCHPRS, it compiles redstone to a graph in rust so it can be executed much faster its the same mod used to make the minecraft in minecraft redstone computer run in real time.

[@skanslovakia553]

Do you think it could be further optimised to render an image faster?

[@georg240p]

Absolutely, Even if you stick with my general design, you could probably make this 2-3x faster just by syncing the individual components and getting the timings right... I only realized halfway through how important timing is. Also a lot of the operations performed don't even come close to requiring 20bit precision - so you could use different data types. I've also been told vectorizing the data could work well for such a simple raytracer. Who knows how much this could speed up things.

[@zeph0shade]

All the crazy computers people have made out of redstone kind of goes to show how redstone is actually more intuitive than complex... The trick is approaching such a project with an understanding of computers, not an understanding of redstone. The mechanics of redstone itself are surprisingly intuitive by comparison.

[@tihan9142]

I have just saw the video of mattbatwings and your video came in front of me 🔥

[@homework8969]

One optimization would be using 0-tick logic instead of regular logic It would still be quite slow but a lot faster than what it is currently

[@mrunboxeryt999]

New calibrated sculk sensor is very useful to transfer a chunk of data from one place to another super efficiently

[@voidbinary]

Out of curiosity. You show the rendering in which it starts from the top. Could you add a coroutine to do the rendering on multiple lines simultaneously to cut down the time for rendering the whole? Or are you bound to having it be rendered one block at a time? On last note I suppose adjusting the tick speed would still break some of the redstone right?

[@georg240p]

Yes, you are right. Every pixel could be calculated independently. and thats exactly what a real GPU does. But in Minecraft, calculating more pixels at the same time just means that more redstone blocks have to be updated. I sped up the entire game to 500 ticks per second (instead of 20) using carpet mod but the game already lags like hell so it's probably only like 200 tps. I would need some more complex ways to get more out of it (data pipelining, better redstone building techniques etc)

Building a 3D ray-tracer using redstone in Minecraft is a challenging but rewarding project that requires a good understanding of both Minecraft's mechanics and the principles of ray-tracing. Ray-tracing is a rendering technique used to create realistic 3D images by tracing the path of light rays as they interact with objects in a scene.

[@hashdankhog8578]

Do you think it would be possible to do full on path tracing with a form of dithering to make so it doesn't look 100% monochrome. Also, this is incredible.

[@georg240p]

Dithering would be easy, it is often done by just adding some noise to the final color of the pixel. And if you use a multi colored screen, it could actually look pretty good. For example you could use gray blocks that use gravity (gravel, concrete powder in white, light_gray, gray, black) and then push these blocks with pistons so they fall down to their location on the screen.

[@mistake_7176]

NOW THATS ENDLESS POSIBELITIES,THATS MINECRAFT THE GAME OF THE DECADE

[@simonkhouryAU]

impressive!

[@seccuenta50ydos]

Very cool

[@josiahmarsh9453]

Ok hear me out... It wouldn't actually be terribly hard to implemented multithreading. You could divide the display into 4 (or even 16, but I question if that would be efficient with how much your world would lag) tiles and have parallel instances of this machine working on a tile each. Since no pixel is dependent on any other pixel to begin computing, you should be able to divide the work from your input between copies of the logic/memory you've built here, and then merge their outputs together at some kind of an asynchronous output listener that puts them on the screen.

[@megathe2136]

You're designing freaking semiconductors!!!
