1:57 We are all edging, aren't we

Finally someone that takes into account edge flow, as someone that does some 'by hand' ascii art, always am a bit annoyed when all of those 'ascii art generators' just do the "bright = big character, dark = small character" and leave at that A way of making it even nicer would probably to have an extra pass that applies some character heuristics, like "if above is '\' and bellow is '/', this should be a ')' ", and also take into account that letter characters also have slopes, so if you have a 'top left to bottom right' sloped edge, the 'q' character also fits it, and a 'V' is where '\' and '/' converge going down, and so on

I was thinking that maybe there was a way to do some additional processing at a higher resolution to better quantize pixel groups that would better match specific characters. Like an 'L' shape would fit better in an ascii pixel where you have two light subpixels on the bottom of the pixel and one light one dark subpixel at the top for example.

Edge isn't new edge, lord

A lot of ascii art uses a variety of other symbols for edges, like V, for sharp points, Y for branching lines, and sometimes non-ascii characters (japanese characters seem common) to get more complicated edges. The art at 6:45 has a lot of examples of this. I wonder how you'd be able to automate something like that; you'd need a lot more than just the angle of the edge. It seems like you'd need to do something complicated with the "subpixels" as you downscale the image to find the specific shape of the edges, and map it to the most similar-looking edge character.

Also, my submission for acerolas jam: LAMB

If you abandon the realtime requirement, you could maybe do something like this: Take the DCT of all the white-on-black characters that you want to be available to the shader. Take the DCT of the section of the image. Find the “nearest” by some metric. This way you can dramatically expand the palette of letters, and have a more organic selection

When I initially clicked on the video I assumed this is how the effect was going to work. But on reflection - and as you say - this would require a huge amount of branching and would run terribly as a GPU shader.

I was thinking maybe you could use locality sensitive hashing to switch between character palettes. You could downscale 8x8 blocks to 2x2 and use 4 hash functions, horizontal and vertical lines, and the two diagonals. Each hash function gives you 1 bit of info: which side of the line is brighter. That gives you 16 palettes you can choose from to determine the best character for the brightness less, which should retain quite a bit more detail. It should be very fast as well, as you're just comparing a few numbers each time without branching.

Cogmind does ASCII art well (it's a futuristic 2d roguelike).

13:15 With fading based on depth, that's my favourite option. Looks amazing.

I wonder how this would look like if instead of just downscaling the image and only matching the character to the luminance, you sampled the original image and looped through more characters to find one that best matches the pixels. This would be quite slow, but there are definitely ways to optimize this lookup. Would be pretty interesting to also see how it works with different fonts.

I've actually implemented this a few months back. Only in C# but I have outlined how it could be done in a shader with probably acceptable performance. It would take a lot of passes and buffers though. I've come to the conclusion that it's not really worth it. It preserves details a little bit better and the output is noticeably sharper - the simple luminance match method has a noticeable blur in comparison - but it's not better by enough to justify it IMO. With a bitmap font, it's still very noisy, the better details are only noticeable if you actively look for them. Maybe if you use antialiased fonts, but that would completely tank the performance. imgur_com/a/f5pQ1Qs (p sure youtube doesn't allow linking off-site so replace the _ with .)

@@sxs512 The way it works is it subtracts the pixel in the font, 0 or 1, from the grayscale pixel in the same position, then adds together the absolute value of the pixels in the 8x8 grid. Obviously, if you subtract a value from itself you get 0, so the character with the lowest absolute value is the best match. This is the most canonical approach, it preserves the most information overall. Not all information is equally important to humans, though. For example, you can distinguish more shades of green than red or blue. You'd need to enhance the edges as in the video to get a more desirable but less technically correct look.

IDK why but the shader rendering actual text characters in the boss fight cutscene as just lines and squares was really funny. You literally Are Text, ASCII shader...

Love this. Your channel has got to be one of my favorites! I can understand everything you’re talking about even though I’m only a high school freshman. It’s all so simple, and your intro with the flashing phrases and the design is peak! I also love recurring bits such as parish being the harbinger of the sponsored segment. As well as the ever popular “but Acerola?” Speaking of which, I don’t know if I just missed it, but I didn’t really get why returnal using a 10x10 text size was so strange. But you manage to put so much information in such a short amount of time that I very well could have subconsciously breezed past it. Another thing I love about these videos.

holy shit it's beautiful 😭 your video definitely convinced me to build my ascii shader

Amazing stuff. Maybe faces looking jumbled together from a distance would make for a great horror game style with all the uncannyness.

Been following the progress for this on twitter. This looks absolutely amazing and might be my favorite video of yours.

Hol' up dude you're like getting buff 🔥 Really interesting vid, always love how much info you're able to pack into these

This is so awesome looking! I haven't gotten into trying to make shaders myself yet, but this is really convincing me to forget about my current projects so I can try remaking this. It seems relatively simple while also looking really cool.

There is a lot of flicker on characters, especially with full square character. Perhaps having some kind of threshold to prevent high frequency changes of the same character like [full square -> @ for 1 frame -> back to full square] would make the image feel more stable if you prevent full square coming up again if there was one recently.

it's insane how well that final result still reads as a detailed image.

Honestly sick well done

Best way to do an add segment I have ever seen. I didn’t even play attention to the add, just the cat lol

Hell yeah new acerola upload!!

Love the vid! I recently made a Asccii art generator in JS that created a bitmask of every ascii character of font size using a canvas and grabbing an image of each character, then cutting the image into chunks equal to the size of a character size. I then find the the best matching asscii mask and use that character, it really worked well in giving small intricate details with the non standard a-z and symbols by using other languages and special symbols. This obviously does not run real time and take about 10 seconds to generate on a 800x1200 image at font 10. Struggled to optimize it to be more real while not losing detail. Amazing insight gained from this vid, thank you!

i love when i understand what you're saying it makes me feel so smort
