Nice to see that work. Much appreciated, Jean Marie. If you have a public source for the formula, I'd love to have a look. Might have some clues for manipulating transformations like this.

Yeah, I have had some luck tinkering around with the parametric modules, but those make meshes and I want to generate 2D/3D point structures. I'd love to see any math examples, especially algebra/geometry vs. trigonometry.

Thanks for that. I certainly need to keep an eye on Magneson's stuff.

Right now I'd really like to sort out how to get this equation to work with the comp I posted. I find using Build List or Process List versatile, and I know how to build onto this method and add features. So I'm trying to get a better grip on how best to take some math equation I find online, solve for y or whatever, and plug it into Vuo. I am trying to chip away at the math to understand it better (algebra/geometry/trig/vectors) hoping that once I get a couple equations to work, I'll be able to implement some other stuff on my backburner.

The attraction seems more like a morph between different curve easings (you'll need the lerp 3d point node posted here).

Yeah, except when the attraction value gets high enough the converging line elements become a loop. I think it's some other interp formula, a 3D point with gravity or something, I haven't pinned it down. Maybe some math akin to what you used in the spirograph node?
