pub const HARMONOGRAPH_TURNS: f32 = 4.0;Expand description
How many turns of t a harmonograph trace runs — the length of the
pendulums’ swing the figure records.
A trace that closes (decay = 0, whole frequencies) retraces its one figure
this many times; a damped one spends them spiralling inward. Four is enough
turns for a moderate decay to shrink the figure to a fraction of its first
swing without leaving a samples-point walk too coarse to fit.
