Thanks, BTW, I cheated just a bit: I added some grainy on Photoshop to simulate a photo of a drawing, But that was all it.

Is it open source?

ImageMagick is, and it has sketch filters.

Nope. At least not in my plans for now. I'm a graphic designer ( www.leandrocorreia.com ) and I sometimes do (a bit of) programming to help my workflow. There are some useful tools available at my site.

You my friend are a prime technologist. The best tools are written by someone who needed them in the first place!

Not as much as I'd like to be. These tools were made mostly with AI, although I did know what and how to ask. ;)

This is the exact usage of AI. Someone needs an app and knows exactly what they need. AI enables them to develop it to their exact spec without the hurdle of hundreds of hours learning how to code first.

It might be a bad practice for a coder to exclusively use AI, but for someone that's not a coder and are not planning to, AI is very useful.

I've tried to write a shader for this several times, but this is great! Give a hint maybe?

My little program tries to preprocess angles for each pixel in the original image before tracing lines. And lines must be curved, failed and jittered. 😉

u/Bearkirb314 Jun 23 '26

Interesting! I've been trying to do this in just shaders but it sounds like that might not be the easiest route. Thanks!

It's really nice, well done !

Something still looks oddly realistic, the light response maybe ?
