[@rowanbcapr]

maybe even soon someone will make a 10 hz computer!!!!

[@boogiehasfun]

@@rowanbcapr probably not because running computers using computers by using redstone is slow on vanilla minecraft, with mods we can probably do this. we’ll just have to see if it ever happens extra non-sense: basically running java code that is deep down made into binary code which creates redstone which is used to make computers that run binary code themselves is very slow with the little optimization that minecraft has.

[@GameJam230]

​@@tronsrop excluding the observer, the target block (which is used quite a lot in redstone surprisingly), and a small handful of containers which interact with comparators, redstone hasn't really been updated all that recently. The Redstone Update came out over 10 years ago now, and it added basically anything that isn't on the list above, from comparators, to redstone blocks.

[@sanderbos4243]

As someone who wrote a path tracer in C recently for uni, massive respect for being able to pull this off in Minecraft! Using maps is a great idea, and as you mention in the description it'd make for awesome wall decorations like they're paintings. You could even construct a massive render on a wall by putting a bunch of single maps next to one another! If you haven't heard of it yet you should look up "Minecraft High-Performance Redstone Server": "It turns your redstone in an optimized graph representation and then does a few basic optimizations on that and then finally just iterates over this data structure to run the redstone." It makes redstone run several orders of magnitude faster! :D

[@hampter4017]

this build won't work with mchprs, it doesn't support observers or pistons

[@sanderbos4243]

@@hampter4017 Right, but the observers and pistons aren't essential to this build in theory, right? It seems worth it to limit your redstone component arsenal when dealing with rendering for literal days.

[@AlbySilly]

Sadly the pistons are essential since it's what makes map rendering possible

[@kerty-]

​@@AlbySilly I think it's possible to remove the display and write a script that will take the result and convert it to an image for faster debugging

[@AlbySilly]

@@kerty- I mean that is true, you can grab the state of a block via modding/scripting/plugins and possibly even having that output create a map with more work. I may be more of a purist when it comes to this though since I'd probably just want to see it in pure vanilla rs logic (probably with a high performance rs server/mod) It'd still be really impressive if it was implemented, I can think of two ways of doing it 1. Take redstone strength in a grid and draw it to the image (The redstone strength at that position represents a color on the image) This is probably fairly similar to how it's done now, sans the pistons 2. Take 3 redstone inputs (X,Y,col) and plot to image (basically give the rendering task to the mod) This would remove the need for a huge square to draw the image and you can basically just read the signals from the output of the dithering machine Actually looking at how he made the screen/data transfer, some changes to the design may be necessary

[@DoggletPug]

I literally can't imagine how frustrating debugging must be. I get pissed when I can't figure out a bug in 10 minutes, this guy has to wait that long for a quarter of the image to load before he knows if he's right in his calculations or not. Seriously good job my man.

[@nikkiofthevalley]

He probably uses speed mods, there's mods that remove the 20 TPS limit and let the game run as fast as it can. Edit: Oh, he was already using speed mods. MCHPRS might help still, but as far as I can tell, he wasn't using it.

[@mz7315]

Sodium can also help, though I think that's just for chunk loading.

[@Pixelhurricane]

I get pissed when the auto-compiler doesn't redline a piece of code that doesn't work right lol, I'd probably die before I could fix a redstone machine like that

[@LtdJorge]

​@@mz7315no, it cannot. The limit here is that redstone works with the tick system of Minecraft, which is 20 per second. So if you add 20 repeaters in a line, it would take 1 second for the signal to cross them, and there's nothing you can do about it.

@@staywokecuhh Although I was talking about getting java to run and all that crap someone already made a 32-bit redstone computer which could theoretically run Minecraft so I concede.

[@ethenaux]

Not sure if this has been brought up to you before but one way you could potentially optimise the machine is by using redstone rails instead of redstone wire. Redstone rails produce far less lag and function similarly (with the use of observers) which should reduce the amount of time it takes to process a single image.

Can you explain more about replacing division by an approximation? what is it called, i want to read about it

[@georg240p]

I'm approximating the sphere intersections by using functions that don't use divisions or square roots. Haven't tested it much but I suspect it will not work well in more complicated scenes. The intersections in my last video were perfect but required a single division (but no square roots and worked with unnormalized vectors) Of course there is also bit shifting, which results in a multiplication or division by a multiple of 2. I also used that a lot to keep the values in the 20bit integer range.

[@ArtisticScratch]

I'm a little confused on how to managed to have the shading in a dithered style, no bare bones render engine comes with that functionality and would (like you pointed out) have very sharp shadows and shading

[@georg240p]

the dithering does not affect the shadows at all. They are still perfectly sharp. - on such a small display it would require a very large lightsource to produce visible soft shadows.

[@ArtisticScratch]

@@georg240p Though I don't understand why or how there's dithering to begin with. Dithering is a technique to add more levels of shading to an otherwise limited color set. but if I'm right a simple lighting setup with basic materials and lights shouldn't produce dithering at all

[@georg240p]

@@ArtisticScratch I explained this around 5:40. Of course there is no dithering by default. I had to add dithering by blending in a checkerboard pattern to the 64color data before it was converted to the final 11 colors. The checkerboard pattern or noise makes it so that the individual color thresholds are triggered slightly offset. This breaks up color banding artifacts. In my example I converted a smooth black to white gradient to only 2 colors. The amount of added noise controls how much dithering is visible.

[@portalwalker_]

Have you heard of MCHPR? From my understanding it is a Minecraft server you can run on your PC specifically designed for building PCs because it handles a few chunks together in separate threads and thereby speeds up the calculation your PC has to do

[@witherschat]

The one thing I'm wondering the most is, how does this map renderer return a grayscale pixel by changing only one of the 16 blocks?

[@georg240p]

it's a scaled map so every pixel on the map is a 4x4 chunk. Minecraft chooses the most common surface block in this chunk for the color on the map. I filled the top-most blocks in the chunk with the colors that i want to display. So seen from above, every block in the 4x4 chunk exists once. Now let's say I push an iron block into the single empty pixel slot. Now the iron block exists twice when viewed from above and because every other block only exists once, iron is the most common block and thus is chosen by the game as the pixel color. And if i push a stone block, stone exists twice and so on.

took me a while to realize, but you're basically coding a fancy shader with minecraft redstone, super cool

[@georg240p]

@@davidvce5035 Yes, they only reduce lag. But in some places I might also have used the signal from the redstone block for a different purpose - I'm not entirely sure. So double check if anything else nearby is affected.

[@davidvce5035]

@@georg240p ok, thank you very much, because I am thinking of using that design to reduce the work of turning the wire on and off in the redstone circuits. I think it is important because I have verified that if a circuit runs at very low FPS it begins to fail, a very characteristic BUG that consists of a cable being interrupted between on and off in the cable path, which is corrected by breaking and returning to put a redstone dust on said cable. Let me clarify, this does NOT happen with your circuit, it happens with a calculator I have.

[@georg240p]

It generates the screen/canvas coordinate system. U is the X coordinate (horizontal) on the screen and V is the Y coordinate. (vertical) Everytime a new pixel has been finished, the VU thing receives a pulse. And every pulse adds 1 to the U value and once U has reached 63, the next pulse will set U to 0 and adds 1 to the V coordinate. The red Subtractors that come afterwards, just convert these coordinates form range [0...63] to [ -256....256] if I recall correctly.

There is an error in the reset, the screen does not reset completely, leaving 2 vertical lines almost at the end of it.

I'm no redstone expert, but I may give an idea to some better solution. Based on an idea and a quick youtube search. If you could live the space empty under the color part of the pixel You could build a column pusher under the pixel something like this: YT video: "Automatic Wall Builder / Conveyor Belt 1.11-1.15" (I think if you build it two sided one piston out, one in it would be invertable) push up a column of something from the bottom so you lift out the pixel one in the middle of the pixels between the colors to get over the piston limit (I don't know if you would give it a signal as it would be a color what would be the result of the pushing) But if it can work after you lift out the pixel over the level of the display, you could build an invertable vertical slime block conveyor so you can move it to any height. YT video: "Minecraft Proof of Concept - Slime block conveyor belt elevator (14w18b)" If it still could work like this maybe it gives an idea to make something better out of it than my description.
