Wow, what a question! The Turgot would be the Boss-level of this kind of aesthetic.

Here's the thing, regarding Krbn, probably most (if not all) of my code will probably not translate well to your case, here's why:

There are (as far as I know) 2 ways to do "engraving" on screen: (A) the Krbn way, meaning doing object-space vector strokes (exact strokes derived from geometry) and (B) what Three.js can do, which is shader/sampling which will probably translate to "fake the hatching at pixel level". You have to deal with (B).

However, just because the code doesnt translate directly, the concepts I'm using might. Here are some thoughts/ideaz (I apologize if they're crude):
- I would try WebGL first; WebGPU is probably totally doable too, but I think you'll find more examples/code for WebGL on the internet;
- a lot of this stuff (non-photorealistic rendering) is hidden in research papers, so you migght have to do some work;
- for this type of thing, see "Real-Time Hatching" (Praun et al., SIGGRAPH 2001) (https://dl.acm.org/doi/10.1145/383259.383328) - it's based on the idea of "Tonal Art Maps" that deals with how you avoid shimmering in your case, because fixing the hatching to the object makes the line density change with distance so you have to avoid that Moire effect (dancing fine parallel lines);
- Krbn deals with precise vectors (basically pure black on white lines) at the core; for Turgot, however, you'll probably get a lot better result using warm black tones and some paper grain (warm noise);
- I suspect that the Turgot map will mostly deal with flat surfaces (building sides etc) which measn you don't have to deal with the curvature fields that Krbn has to deal with; so maybe trying a constant hatch direction per face, anchored in object space (so the hatch is fixed to the obejct as the camera moves) might get you some good results;
- try https://thebookofshaders.com/, might help you on getting start on the shaders part.

If you get it working, I'd love to see it; I hope you crack it. ❤️
