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.

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.

[@LordPfrog]

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!

[@sorean4532]

Insane tech but what amazes me the most is the amount of passion, knoweledge, patience and effort you had to invest on this project

[@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

[@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.

[@lilv728]

Bro this is just unbelievable. The amount of work you probably put into this. Good on you! Great content for sure!

[@Oneye.]

Great high-quality content, and good explanations! Commenting for the algorithm.

[@russianyoutube]

That is awesome! Good luck in future projects

[@PNWMan]

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.

[@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.

[@nano_redstone]

Very cool build I can't wait to see the future !

[@g45h96]

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.

[@walksanator]

Question: is your Redstone "pipelined" which means that although it takes 10 minutes to render 1 pixel it is doing each pixel one after the other Rendering the entire thing in 11 minutes instead of 100 for horrible example

[@walksanator]

After watching: no it is step by step

[@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)

[@weltkaiserendzeit2417]

I wonder if what makes the computer so slow is the use of repeaters, in which case maybe we could accelerate it by using 0-tick repeater or something like that. That would be a "quantum computer" in minecraft ?

[@imthecryptic]

I think instead of updates being buffered at 1 tick a 0 tick repeater would just run at your game’s speed. It would still be really cool to see though

[@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

[@whtiequillBj]

does the multiplier have two registers for input and a register (input slot) of its own for output before it goes onto or comes off of the bus? Cause that is how your explain it in your example.

[@georg240p]

The output is cancelled with comparators on subtract mode. When the 2nd input slot gets updated, the output is opened automatically once the calculation is done.

[@photoncraft1109]

Great Job. You Deserve 1M Subs

[@thephoenixking1086]

Random Thought: Can you do something like a PWM with the Redstone lamps, flashing them on and off so fast that the brain thinks it is getting dimmer, this is how most Dimmable LED's work, they just turn on and off so fast that your brain sees it is less light. Doing this with the lamps (and maybe the game sped up) would in theory allow ONE Lamp to show multiple shades of Gray, you could make 16 Shades of Gray + B&W to get 18 Shades, you could then use those 18 shades to make rasterised graphics instead of line-art style graphics (Like a B&W CRT Vs a Vectrex). So far, the Lamps in Minecraft to me look more like a Vectrex, aka they are just two shades, White or Black, and are line-art, but if you PWM the lamps you could in theory make them look more like a CRT, allowing for WAY more shades therefore much more detail. I have no idea if this is possible, if PWM'ing the lamps would work or not, but when you showed a time-lapse at the start of the video, the lamps were turning on and off very fast and this to me looked Dimmer than normal, what I saw was a new shade of Gray meaning this theory may be possible. I do not know if it has already been done.

[@thephoenixking1086]

This in fact is how OLED works, the multiple millions of colours are derived from three RGB Sub-LED's brightness being changed and your brain seeing it as a new colour. In the case of the lamps in Minecraft, they would be B&W but you could still see details like a rasterised graphic instead of Vectorised graphics. Who knows, I think this is a fun idea, too bad I have no clue how to do this in the game hah. I challenge someone to do this!

[@storminmormin14]

“I built a ray tracer.” No my friend. You built a full fledged computer and programmed it to ray trace.

[@benjiman528]

I was under the impression that the described rendering technique was ray-casting, not ray-tracing. Wouldn't ray tracing require recursive traces from the initial trace hit coordinates?

[@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.

[@GoldenAdrien]

HOW DID YOU DO BITWISE OPERATORS IN BLENDER? I HAVE BEEN TRYING TO DO THAT FOREVER

[@georg240p]

You can simulate bitwise operations with floats in the range 0...1. For example a NOT gate is just 1-x. an OR gate is just: clamp(A+B, 0,1). And an AND gate is: A*B. You can create Nodes for each of these. But I did not simulate all the operations with individual bits - I just used truncate() to simulate integers and I used modulo() to keep the values in the 20bit integer range. The results are exactly the same - it's just a lot less work. btw the orange nodes with the zeroes and ones are just notes that I added so I can debug these values in minecraft.

[@temhgb]

Damn, how is this even possible? Btw it looks like a a load of the connecting wires in between modules use repeaters, I’d say you could speed the computation up quite a lot by using pistons with Redstone blocks attached instead?

[@pavelmatusu4457]

You should build a GPU to compute the pixels in paralel. The gpu should be constructed out af many very simple cores. The cores would basicaly be just a ALU with a few registers and the controll logic would shared by all of the cores. In other words there would be a core controller that would send to the cores commands like: add the value of the first register to the value of the second register. All of the cores should have a outpurt buffer outputting to a pixel, so there would be a core for every pixel. This build would be really gigantic depending on the number of pixels but also much much faster. Algorithm for calculating intersection with spheres is quite compicated but the frame times should in munutes per frame. edit: Im making a simple gpu in minecraft myself so i kind of know what im talking about.

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.
