Ascii Elden Ring??? | Prime Reacts

Acerola is the goat of doing random shit with shaders

Acerola is just fantastic. His video so effortlessly mix shit-posting, meme-ing, pragmatic problem solving, application of math, all while projecting a sense of comprehension into the viewer. To be honest, I don't understand the math behind some of his VFX programming, but he makes me feel like I did. I'm really glad Prime picked this up, because Acerola deserves the visibility this will bring to his channel.

Need more reactions of acerola videos from prime. This guy is a magician with shaders

Prime reacting to an Acerola video? Damn, that’s a pretty good birthday present

But Acerola 😳

Prime should 100% watch the pixel sorting shader video

I’ve pre-watched this Acerola vid

2:52 Having seen the original video before, I was waiting for the moment where Acerola would say it wasn't good, just after Prime was saying it was good. Got a good chuckle from me.

Before I discovered atan2, I had to make “atan2 at home”. The atan (arctangent) function takes the slope (ratio of y/x) and returns an angle. Unfortunately, you lose information if you just provide it a pre calculated ratio such as whether either or both of the components were negative, so classic atan can only give you an angle between [-90, 90]. atan2 takes the components separately, so it can also use a bit of logic to return all the angular values [-180, 180].

ASCII does not define the font or design of characters but the map between byte and character representation. Extended ASCII is not an encoding by itself (confusing, I know), but a classification, or "repetoire". Many OEMs would create their own version of Extended ASCII, some being ANSI-compliant, while others not. DOS and Windows, before Unicode was formed, would have their own Windows-1252, while other OEMs like IBM had their Code page 437–as you probably know from IBM PCs boot screens and BIOS menus. The latter has box-drawing characters included, where the former uses them for accented characters. For example the box drawing character "block" (0xdb) in CP437 maps to a █, but in CP1252 maps to a Û (u-circumflex in CP1252). Both are in the Unicode standard (which is why you can see them in this text). So no, there's not one right way to represent ASCII art. It is totally up to the character set and font design. You could say it would then be "ANSI art" since they extend ASCII, usually with 1 extra bit, but lets not be pedantic :)

TIL Acerola exists, and my life has been enriched.

Acerola is a very great guy, you should watch more of his stuff, it's always super interesting and cool

That's where the phrase "image is worth a thousand words" began

Acerola is dope. I love his videos and he deserves recognition.

It's crazy how toxic chat was at the beginning just because Acerola stated his artistic opinions, but as soon as he started talking math and showed off his edge detection, suddenly chat was super kind.

Let’s goooo baby! Acerola is OP

splitting the luminance linearly into bins feels like such a bad idea since brightness is a log scale. It would probably look a lot better if you use more bins for the darker values

If the Sobel filter is an approximation of the gradient, the difference of gaussians is an approximation of the Laplacian (the divergence of the gradient). Intuitively, the Sobel filter looks only at first derivatives, while the difference of gaussians is looking at the second derivative. I think what the difference of gaussians is doing here is effectively removing large scale contrast variations (makes things hard when thresholding for edge detection) and blurring out noise (with the gaussian filtering), so that the Sobel filter has something cleaner to work with.
