Real

but every pixel costs 35 dolars

hi, I'm newbie at graphics. what do you mean by prohibitive? isn't offsetting a blue noise texture enough to give you that variation?

@@xYAuronYx blue noise is notoriously expensive to compute and therefore not very suitable, if at all, for realtime. unless you'd compute it beforehand, then apply it to halftone your image. this is what is done here but on static images. if you want to do it over an animated image, the halftoning wouldn't budge; it would just be a static mask over the moving image. if you want to avoid the staticness you can either generate noise at runtime or prebake an array of different noise seeds that you will apply in turns over each frame. so it would look like it's moving-textures are expensive too but almost certainly less than computing blue noise. other types of noise, like real white noise, are pretty cheap but they won't give the same quiet and quaint effect.

I think that last point depends on the game you're shading, honestly. We've seen that it gets less playable if you apply this shader to a random game like journey or cyberpunk, but if you design the entire game knowing that it'll be run through this shader afterwards, you can make creative decisions that preserve clarity. Also, adding some color by means of cel shading or an equivalent alternative would help. There's already games that are hand drawn, like cuphead or neverending nightmares, and 3d games that are cel-shaded, like borderlands, so I believe with some extras this shader could fall into that same category, with the added benefit of actually making every frame look like a hand drawn panel of a comic book/manga, instead of looking like a collage of distinct pictures at best.

@@KarachoBolzen journey could look really cool with this IMO, as long as the contrast was turned up a decent bit.

@@KarachoBolzen Return of the Obra Dinn looks a bit like this shader.

thank you so much!

Thanks! I'll probably be releasing a video similar to this one within the next few videos since I've learned infinite since I made this video lol

in the next video I go over how I did hdr injection for final fantasy xiv so i hope you like it!

The music is the Halloween Town world theme from Kingdom Hearts

Thanks! In the event all my career ambitions fail I will probably become a professor

@@Acerola_t lmao, I almost spit out my drink right there haha

Thanks!

I def made the music too quiet in this one lmao

Probably not very well lol, you'd do a different approach for a moving camera since in that context you'd have actual scene information and can use depth/normal info for edge detection rather than the image effect edge detection algorithm.

​@@Acerola_t this, and from what I've seen, screenspace textures look pretty bad in motion, you would have to use worldspace projected noise textures like in borderlands or else it's nauseating to play.

yeah the theory applies to blender, although blender isn't meant to be real time so you can use much higher fidelity techniques with it

It is applied through a fragment shader in unity, just applied to a png that's blitted to the screen in the Unity editor. I haven't tried it out on a real 3d scene though, maybe I'll revisit this effect and try and improve it for October this year.

@@Acerola_t I would love to see games in this style. A lot can be done with this!

@@ShignBright take a look at 'Return of the Obra Dinn'!

If the effect were made for a 3d scene yes, but this effect was made to work on generic images like a photoshop effect.

Cause the algorithm is intended to run on images not 3d scenes therefore there is no depth.

I wouldnt recommend running it since it's kind of made for me, but if you download the code you can attach the c# script to the camera and fill out all the public variables and press play. I'd recommend just referencing the code if you want to use it yourself.

@@Acerola_t okay , thank you so much

@@Acerola_t this is amazing, thanks, I downloaded the code but I'm not able to reproduce your results, any tips?

I use Unity, unfortunately a good software for applying shaders to generic images doesn't really exist.

I do a lot of creative image processing. There are a hundred approaches to this. For one-time work, I do things manually in GIMP. Anything GIMP can do, PS can do too, afik. One bad thing about manual image processing, doing things step by step is if after 50 steps you realize that a setting you used in step 5 should have been a little different, you may have to ^Z undo your way back, tweak that setting, then re-do the next 45 steps exactly the same. Better to build some sort of pipeline that automatically recalculates all follwing steps if you tweak one of the earlier steps, like how a spreadsheet works. For batch processing or ongoing jobs, I write code in Python or Julia. I have a kind of toolbag of routines for sharpening, edge detection, color adjustments etc. Easy to make a pipeline with adjustable parameters. If I need to do something tricky to code but easy to do in GIMP, I write a command line or GUI app in D, C++ or Vala code using GEGL, the core image processing code used in GIMP. Whatever I do manually, I can do this way too. For someone who doesn't mind writing some code but doesn't want to go deep with full-blown applications programming, there's a way to script GEGL operations inside GIMP, even with multi-branched pipelines, so whatever processing you do today you can save to re-use later. I might experiment in Blender where the input image is just a flat rectangle and processing is done with material nodes, but most of that is point operations, no blur or unsharp or median filters. But I can replace a still image with a video texture. There are some GUI apps that let you drag nodes around and wire them up in intricate ways, like the nodes in Blender or other 3D apps. TouchDesigner had something like that, and you could write custom shaders in code, but I haven't used it in a while. Unreal is the king of the graphics tool world, as it has everything. I'm not familiar with its image processing capabilities, if you want to do advanced algorithms but not be doing any 3D. Something I need to play with one of these days... For scientific work in astronomy, I write code in IDL, a cuss-worthy language based on a horrid mishmash of C, Fortran, BASIC, Matlab and outer space alien. But everyone's been pushing for more Python and somewhat also for Julia. Avoid IDL!

Cause I didnt have a good scene to apply it to at the time, hence why it's intended as an image filter. No, the performance isnt that awful considering the canny edge detection filter is pretty much the first stage of FXAA.

no way

This effect wasnt mean for video, just still images

Return of the obra dinn looks much diff but yeah they do use blue noise for half of their dithering so the pattern is similar.

@@Acerola_t it does look different but it’s similar in the stylised shading

yeah sorry these older videos arent as good

It wasn't made to be used in motion, it was made to operate on still images so that I could use it for making assets.
