(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.
Big thanks to @mattbatwings for their amazing Redstone Tutorial series.
Many parts of my build are based on these tutorials.

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!!
Came here from you
Hey man!
Great recommendation!
Hey mr bat
came from u
Dude this is crazy for one of your FIRST redstone builds??? Everything was explained so simply and the graphics you had to accompany made it so easy to follow!
I could have not said it better
He's cracked at redstone
What you mean first 💀?
@@Nombrenooriginal first showcased redstone build
@@yoshin6465 everyone's first showcase build is the one they think is a magnum opus
4:45 Unironically I think you just taught me something about physical computer architecture that noone else has managed to teach me in 8+ years
Unironically same
If your interest is still whetted check out "But How Do It Know". Written for average people, it goes from a light switch to how a whole simple computer works. Logic gates, ALU, memory, clocks, instruction decoders .. etc.
Same lol. Makes more sense now
Sure enough, that's the concept of a bus!
i had a test where i had to use that yet this is for the first time i realised how it works xDD
The rest of the Minecraft community is trying to figure out what a Sculk Sensor is and georg just built a Redstone Ray Tracing machine in a version of Minecraft that doesn't even support Ray Tracing
*officially
Rest of the mc community? Don't forget the other redstoners who also build big builds
@@roykale9141 what do you mean
1.7.10 is the best version
for modding
@@Treetrain1 There are shaders with raytracing
My man is taking Minecraft RTX to the next level. Truly an insane build.
"Java doesn't have native ray-tracing? We'll see about that!"
We've seen people download RAM but now you can download RTX too. Truly incredible
We really live in the future 😂
Always cool to see someone pushing the boundaries of redstone graphics
boundaries with current hardware
If only they optimize the redstone.
Absolutely insane build, and very smart approach of using a "special case CPU" for such computations, it's not an approach we see often. :)
yoooo this is crazy dude
have you heard of MCHPRS? it's like carpet mod except the speedup is more on the order of 10,000x (so builds of this size can run within a reasonable amount of time), definitely recommend if you're gonna be making more stuff like this
Yeah, he should seriously use the MineCraft High-Performance Redstone Server, it really speeds things up to awesome levels.
I joined the test server when they were first testing it.
It was funny to see how fast things could go if you ignore everything except the redstone itself...
I’ve been thinking of going there with my build. Are there any requirements like minimum release versions, time constraints, build size etc?
Seriously impressive, especially for one of your first redstone builds! You earned my like and sub :)
This has to be one of the most insane things ive seen in my 12 years of playing this game, good job
This is going to feature on one of those "top 10 craziest redstone builds" alongside the other mental cases making this type of stuff, great job man! wish i had the mental capacity for it myself
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 was an awesome project and your video describing it was great! I really appreciated the insights into how to prevent just chaining pieces because that gets really confusing really quickly. Instead, having this instruction set feed and your explanation on the way you'd like the adder and multiplier etc, really helped me understand how to think about this kind of project! The blender recreation was really cool too! Thank you!
That's insane, some hard-core madness right there. Congrats man, amazing content.
That’s really cool, and you explained it very well. Unironically taught me something about actual everyday computers I didn’t get. Good job!
This is so cool! Good luck in new projects!
That is awesome! Good luck in future projects
This is underhyped, the amount of effort put into this and logic put behind it is immense.
Keep up the work!
Before watching this video, the idea of a Redstone raytracer was foeign. By the end of it not only did I see it and it was functioning, but I understood how it worked. This video is one of the best videos I've seen of this topic.
Crazy. Its all magic for me but it is incredible! Great work! And i cant imagine what wiöl be build in a few years
Very cool build I can't wait to see the future !
This is insane, you watch one tutorial series, and then you make a perfect ray tracer, amazing but also unbelievable, maybe you could help some major mc PC project
Amazing clear and fast summary
This is amazing, I wish I could do this level of stuff. 10/10 content, keep up the AMAZING work!
Underrated brooo
The people who just make a 2x2 door get way more attention rather than this masterpiece bro your on the same level as sammyuri and mattbatwings😯
Great high-quality content, and good explanations! Commenting for the algorithm.
Amazing video! Awesome work and a very intuitive explanation :D
Bro this is just unbelievable. The amount of work you probably put into this. Good on you! Great content for sure!
Insane tech but what amazes me the most is the amount of passion, knoweledge, patience and effort you had to invest on this project
This is amazing, great work.
Awesome video dude it's insane what can truly come from redstone
Goodness gracious!!! What an excellent breakdown!
do not team up with sammyuri
Hey can you please respond to my reply 🥺
Wow, awesome man!
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.
Never fails to amaze me how redstone can be utilized by someone, this is some seriously amazing stuff dude.
I'm just speechless, just how amazing this is.
I actually sort of understood most of this. Great work.
You taught me more in a video then school did in a year
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.
This is so cool! 😊
Amazing!! Nice video
What a flex, nice work
This is soooo cool Incredible
man, i feel like during a lecture. good job
Definitely also recommend Sebastian Lague's computer experiments, they're very informative!
redstone explains how computer codes such as 1 and 0 codes work great job btw
I love how you explain it, not just show it
This is amazing! Can't wait until ray traced minecraft somehow becomes playable in unray traceable minecraft
a truly masterminded redstone engineer lmao
Really interesting!
I'm surprised that I understood A LOT. Great content, great teacher
Well done!
okay wtf THIS IS MAD IMPRESSIVE!
Awesomely awesome and kick awesome.
nice work! fun
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
It probably is but theres advantages to both
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.
yo this is super cool!
This is so cool!!
Great Job.
You Deserve 1M Subs
Holy shit this is awesome but i like going outside 😢 hope this mans took a long break can't imagine how long that took
bro just broke down bus theory in a really beginner friendly way. i'm proud
Wow crazy dude… Even your red stone system visually is very cool and easy to understand… (i mean how works, not to make it 😂)
today, on stuff that i will never build, but i enjoy watching people do. xD
О того количества механизмов в этом видео у меня глаза расширились от удивления!
New calibrated sculk sensor is very useful to transfer a chunk of data from one place to another super efficiently
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
You should get a job for a chip manufacturer 😊 awesome job ❤
This is complicated on top of complicated, insane.
always loved seeing people go ham with redstone lol
such a good video ngl
we've all been waiting for this time
finally, ray tracing in java edition
(although it's not)
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
You are amazing.. I don't know why am I only finding you 😋
Amazing video
I love how the structure looks like a giant computer , and it IS a giant computer
Interesting, my favorite part is when the do-hicky does the thingy with the whatchamacallit instead of a kajigger.
My dude!! Hex is next!
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.
Do you think it could be further optimised to render an image faster?
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.
huh, so this wasn't clickbait after all, glad I clicked
if you want use color you can use a map display. i can help with that if you want, since i know a lot about those
You're designing freaking semiconductors!!!
when i first saw this the most impressing thing was the size
size is usually a bad thing for redstone stuff lol. The goal is ususally to make it as compact as possible.
I love how hes blowing up a second time
Instant wires could also add to efficiency
Crazy crazy work. The single bus design is no doubt the simplest way to go, but terribly inefficient. If you were to make a seperate input and output bus, as well as input and output registers on every logical unit, you could do what's called pipelining. Which basically boils down to decoding an instruction and preloading the data, while the current operation is executing, while the data from the last operation is being sent to where it needs to be. Say, for example, those million cycles it runs. Right now nothing is synced by a clock, meaning operations could take anywhere from 1 game tick to I'd guess 15 or so. The operations wouldn't get any faster, but, effectively, an operation would be completed every 1-5gt. Those million cycles, that at a 15gt average takes 8 days, would complete in a little under 3 with a 5gt average.
We're so close, soon enough we'll be able to actually properly run doom in minecraft
Very cool
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.
impressive!
I have just saw the video of mattbatwings and your video came in front of me 🔥
dude woke up and was like "I'm going to build a ray-tracer in minecraft"
NOW THATS ENDLESS POSIBELITIES,THATS MINECRAFT THE GAME OF THE DECADE
This guy is the NileRed of redstone, soon enough he's gonna make a "I made a real life working nuclear bomb using redstone" I swear
run this world on a shitty pc and thats how you get a nuclear bomb
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.
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.
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.
Wouldn't using powered rails and observers for the wires faster than redstone dust and repeaters?
