Module curves 

Parametric curve samplers: pure t -> (x, y) functions written straight into a preallocated segment buffer. Cheap enough to resample every frame (ADR-0007 parametric build model), so continuous audio can sweep the shape live. Deterministic: no wall-clock, no randomness — the same parameters always yield the same segments (NFR 6).

Structs

CurveParams

Everything a family’s walk needs, by name.

Levers

The family-specific levers: each is read by one family and is inert on every other, so none of them can move a rose.

Constants

HARMONOGRAPH_TURNS

How many turns of t a harmonograph trace runs — the length of the pendulums’ swing the figure records.

SMOOTH_CORNER_SHARE

The largest share of a Maurer walk’s vertices that may be corners before maurer_rose_pieces declines to fit it — is this a curve at all?

Functions

maurer_rose

Sample a Maurer rose into out (cleared first).
