Long story short: I have a blend setup that will mimic the engraved line cross-hatching style that one sees on old, old documents (see US paper currency for examples).
But to make it work at many resolutions, I have to feed it a set of huge 16000-px bitmaps. Each image is of some wavy, parallel lines. Some are thicker. All are perfectly aligned and look like sine waves.
To make it useful, I have to resize or remake those sets of lines, as bitmaps. Otherwise some illustrations will look pixellated.
I’d rather it be scalable… resolution-independent.
Seems to me that I could replace the bitmaps with procedurals, but here are the obstacles I ran into (can you help?):
- I need to make a sine wave output from some node, somewhere in blender Cycles. I tried a lot of things on my own. I searched a lot of topics here without finding a simple sine wave texture output yet.
- I need to adjust that sine wave node to make the lines thicker without affecting the line spacing.
- I need to feed that procedural sine wave texture into Compositing nodes.
Can it be done?
BTW, if I get this working, I’ll be sharing it with the blender users of the world, baby.
