System: parametric_curve

Structural

Parameter	Default	Range	What it does
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.
mirror_order	1	1 – 12	Repeats the geometry this many times around the centre; 1 draws it once.

Modal

Parameter	Default	Range	What it does
n	6	1 – 24	The rose’s petal number, read as a real frequency: a fraction between two counts draws an open web rather than a rose.
d	71	1 – 360	The step between sampled angles in degrees, which is what turns a rose into a Maurer figure; any real step draws a figure.
phase	0	0 – 1	Rotates where the figure starts sampling, as a fraction of a turn.
radial_offset	0	-1 – 1	Pushes every point out from the centre, opening the figure into a ring.
samples	361	16 – 2048	How many points the curve is drawn from; fewer reads as a polygon. Truncated, so a rise adds its next point on arrival.
thickness	2	0.5 – 12	Stroke width in pixels at the render target, before softness widens the falloff.
hue	0.6	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.
hue_spread	0	0 – 1	How far along the palette the colour travels from one end of the figure to the other.
saturation	1	0 – 1	Pulls the scene’s colour toward grey; 0 is fully desaturated, 1 is the palette’s own.
palette_mix	0	0 – 1	Crossfades from the preset’s palette to its second one; 0 is the first, 1 the second.
palette_contour	0	0 – 1	Draws a line at each band edge when the palette is stepped; 0 draws none.
spin	0.1	-2 – 2	Turns per second the whole figure rotates by.
scale	0.9	0.1 – 2	Size of the figure within the frame, before the shared zoom is applied.
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.
glow	1	0 – 4	Brightness of the halo around each stroke, on top of the stroke itself.
softness	0.25	0 – 1	How far a stroke’s edge fades out; 0 is a hard line, 1 a wide glow with no core.
stroke_blend	0	0 – 1	Moves the stroke from additive light toward opaque paint, so crossings stop brightening.
draw_progress	1	0 – 1	How much of the figure is drawn, from its start; below 1 the line is still arriving.
zoom	1	0.25 – 4	Scales the whole scene about its centre; above 1 fills more of the frame.
pan_x	0		Slides the whole scene sideways, in the scene’s own units rather than pixels.
pan_y	0		Slides the whole scene vertically, in the scene’s own units rather than pixels.
mirror_reflect	0	0 – 1	Alternates the repeats into mirror images rather than plain rotations.
