How it works

The spider walks the real orb-weaver sequence: a fixed frame first, then N radial spokes walked out one at a time from the hub, then a capture spiral traced outward as r(θ) = r₀ + (R−r₀)·θ/θmax. Silk length isn't decorative — every segment's true Euclidean length is accumulated as it's drawn, so "Silk used" is a real arc-length integral, not a counter.

Once the spiral finishes, condensation is decided by physics, not a timer. The dew point is computed from air temperature T and relative humidity RH with the Magnus–Tetens approximation:

α = ln(RH/100) + 17.62·T / (243.12 + T)
Td = 243.12·α / (17.62 − α)

Thin silk radiates heat to the night sky and cools below the surrounding air by a few degrees even while the air itself stays put — modelled here as an exponential approach to a fixed radiative deficit. Dew only beads once that falling silk temperature crosses below Td: push humidity down or temperature up and the dew point drops out of reach, and the strands stay dry even after the full cooling window — exactly like a dry morning with no visible dew.

  • Spoke tension — a regular N-spoke wheel under a uniform radial hub load distributes tension per spoke as T = W / (2N·sin(π/N)); fewer, wider-spaced spokes each carry more load.
  • Restart weaving — rebuilds the frame/anchor geometry immediately so spoke-count and radius changes take effect without waiting for the loop to finish.
