When you randomly come across a tech channel... Dig the presentation style and watch more... Only to find one of your old papers being the topic covered in the video 🤯 The pronunciation of my name leaves something to be desired, but the rest of the explanation and delivery was something I only wish I would've had the skills or time for back then! Super well done 👏Keep up the good (and entertaining!) work

omg how flattering, your work is by far my favorite post processing effect I've implemented sorry about pronunciations! I try my best lol

This video, particularly the edge tangent flow and line integral convolution, helped me out a tremendous amount with my job, and led to a breakthrough in a problem I was working on. This is particularly surprising, considering my work has nothing to do with video filters - but it's not an exaggeration to say this saved me weeks, maybe months, of fumbling around. Thanks mr aceroller :)

Randomly changing cross hatching direction in real time every frame (or every few frames) might give you an animated look, like its being redrawn or something

@@khing5720 maybe by selecting the cross hatch direction locally with some kind of continuous but varying noise? Varying the noise parameters could vary the "wobble" effect's intensity and frequency. Maybe you could make it totally random temporally so it looks like it's being re-drawn every frame (or every several frames)

You would probably want to lock the framerate of the changing crosshatch texture to something low, like 12 fps. Maybe make it dependent on a motion vector extracted directly (good luck) or derived from depth & normal buffers.

The intersection between art, math, and computer science here is amazing.

if you had a quantum computer, you could try all variations of the parameters at once, and then use the quantum reverse fourier transform to extract the one that you think looks the best using a neural network trained on your preferences

At first I thought this was just an insane joke, but then I realized this could be totally possible! We just need a NN designed for dealing with quantum sines, allowing us to connect it directly to the superposition, no need for FFT!

As something of a cultured nerd myself, I approve of this technobabble 👍

i think it'd be super cool to use the vector flow field to drive the rotation for the crosshatching texture, with the first and darkest layers being parallel to the VFF and the additional layers being varied parpendicular angles rather than random rotation. This would give you a more accurate crosshatching pattern that takes form into account rather than just using raw values.

This is top tier content. I'm eternally grateful for a great knowledge you've provided Acerola. I can't stop thinking of an infinite possibilities this technique provides

"in signal processing" triggered my fight or flight

Love the references to Monogatari series and Tatami Galaxy! And love the use of Persona music too! The explanation is very good too, I should try watching it when my brain isn't melted due to lack of sleep though

What a banger video! Not only did you manage to reteach me complicated topics I had encountered in a more intuitive way, supported by examples, but also you manages to sustain the feel of a casual conversation throughout. What a video. Subscribed.

First video i watched from you. The explanations are technically in depth but still easy to understand. This makes me want to watch more Videos and learn more about the topic. Great work

I love the pencil cross hatch! Please continue making more videos!

This is awesome! I love how you actually go into the technical details.

You're a seriously great communicator. I wish I had this back in my undergrad visual computing classes.

That's so crazy that artstyle can be defined by equations and numbers. To be able to bridge art and logic is mind blowing

Amazing! Yeah, that's all I have to say for now - I haven't worked much with this stuff myself, but watching this has made me excited to explore further.

One of my new favorite channels to watch! Funny and educational

"It's kinda like the stellaris tech-tree" "Image processing / stellaris" is the intersection of topics I would've expected to see on youtube when I woke up this morning

You are special, I enjoy how much you seem to enjoy making these :)

idk why but the arrow with the transparent background got me better than anything else today. very silly and good comedy

Very clear and amusing explanation. I like the format as well. Keep it up!

crazy dedication man, not sure how many other creators have invented a time machine to improve their stuff, but you're part of a select few

I really like the crosshatch and watercolor ones. Your videos are amazing!

Mad props for using the Sonny Boy OST in the background, that show slapped!

I'm only 2:30 in, but holy cow, you have provided so much useful information that is easy to understand. Thank you!

Calling it the DOG is way funnier to me than it should be. I don't really care about shaders, but calling it the DOG kept me watching. Also loved those transitions, this is a well-made video :)

I'm a simple guy. I see Tatami Galaxy, I like.

Woah, that crosshatching style looked amazing!

That moment at 1:35 with the chicken has me dead. I couldn't believe it. I was genuinely shocked it worked so well and the glasses just add that spice

Very cool! Happy holidays!

Your passion for this is really showing through. I'll probably subscribe soon, but I'll watch another video or two first.

I can't explain why, but this video feels like a masterpiece to me. Great work man, keep it up!

I could totally see stuff like this being used for in-game cinematics! Like cutscenes, quick scripted action events, or just stylised screenshots. Could even go as far as a stylistic theme / visual concept for the entire game. In a game, you'd also have things like depth buffers and surface normal differences available to provide a guide for the "true edges", and I wonder if the algorithm could be adapted to use that as a form of guidance/correction.

I liked the charcoal pencil filter best, but it was all very cool! Thank you for another visually and mathematically interesting video!

I don't have enough words or actions left to praise you the minimum satisfactory for that high-quality content. Thank you ❤

I think my favorite was the last one, though I think there is a lot more to explore with color which can significantly elevate it for certain use cases. Regardless, awesome video as always!
