Nubus & Spindle
Hey Spindle, I’ve been experimenting with a script that renders recursive mandala‑like patterns—mixing geometry with code. Do you have a favorite algorithmic design, or want to tweak the symmetry for an extra splash of elegance?
That sounds like a beautiful playground for the mind, I think the best algorithmic designs are ones that give me a clear set of rules to follow, like an L‑system. The recursion is a joy, because each step follows a precise pattern, and the more iterations the more detail I can control. If you want a splash of elegance, try enforcing a higher‑order rotational symmetry—maybe a 12‑fold group or using a golden ratio fraction of the full circle. A small tweak, like reflecting across multiple axes before rotating, can create that almost hypnotic balance. Let me know what you’re working on, and we can tweak the symmetry together.
I’m tweaking a 12‑fold L‑system that starts with a base triangle, then at each iteration I reflect it across three axes before rotating by 30 degrees. I’m still hunting a clean way to embed the golden ratio in the scaling factor. Got any ideas on a good way to weave φ into the rule set?
A clean way to sneak φ in is to let each iteration shrink by a factor that is a fractional power of the golden ratio. For example, use a scale of s = φ^(–1/12). After twelve steps you’ll have multiplied by φ^(–1) overall, so the whole mandala keeps the same “size” relative to the original triangle while the pattern itself carries that φ‑related contraction at every level. It’s a neat, predictable way to embed the golden ratio without breaking the 12‑fold symmetry.
Nice, I’ll plug that in. That way the whole figure stays proportional to the start shape while the details echo φ. I’ll test a few steps and see how the angles play out—maybe the 30‑degree rotations will line up with the golden spiral nicely. Let me know if you spot any glitches.
Sounds like a solid plan—once the scaling settles into φ, the 30‑degree jumps should nest nicely with the spiral. If anything looks off, just check that the reflections and rotations are exact multiples; a tiny floating‑point slip can throw the symmetry off. Let me know what you find.
Got it, I’ll log the exact matrices for the reflections and rotations so I can compare them step‑by‑step; that should catch any drift. Will ping you when the first few iterations line up—or when I hit a weird asymmetry.
That’s the right approach—tracking the matrices will catch any tiny drift. Keep me posted on the first iterations, and let me know if something looks off.
I’ve got the first four iterations logged—everything’s lining up, but I’m running a sanity check on the rotation matrices; if there’s a floating‑point hiccup, it should show up in the trace. Will ping you when the 5th cycle is ready.
Great to hear the first runs are clean—keep me posted when you hit the fifth cycle.
5th cycle’s in the queue—will double‑check the matrix trace for any drift before I send the pattern out. Stay tuned.
Sounds good, just let me know if anything looks off.
