Structural

Parameter	Default	Range	What it does	Group
mode_n	3	chladni 1 – 16; inert on escape_time	The plate’s first mode number: how many nodal lines cross one axis. Equal to mode_m, the two waves cancel and the plate is blank.	shape, main
mode_m	5	chladni 1 – 16; inert on escape_time	The plate’s second mode number: how many nodal lines cross the other axis.	shape, main
iterations	64	escape_time 1 – 512; inert on chladni	How many steps an orbit is followed before it is called part of the set; more resolves finer boundary detail. Capped by the quality tier.	shape
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.	colour
palette_contour_style	0	0 – 3	Which line the contour draws: 0 a soft darkening, 1 a hard one, 2 a soft ink, 3 a hard ink.	colour

Modal

Parameter	Default	Range	What it does	Group
line_width	0.04	chladni 0 – 0.3; inert on escape_time	How wide a band around the nodal lines lights, in plate units (the plate is 2 across); 0 is a one-pixel line.	shape
plate_mix	0	chladni 0 – 1; inert on escape_time	Blends from the nodal lines alone toward the whole signed wave, which reads as a standing wave rather than as sand.	shape
c_re	-0.8	escape_time -1.5 – 0.5; inert on chladni	The real part of the Julia constant: the lever that reshapes the set, from one connected piece to dust. Inert on the mandelbrot map.	shape, main
c_im	0.156	escape_time -1 – 1; inert on chladni	The imaginary part of the Julia constant. Inert on the mandelbrot map.	shape, main
escape_radius	16	escape_time 2 – 256; inert on chladni	How far an orbit must travel to count as escaped; larger smooths the colour bands’ spacing.	shape
power	2	escape_time 1.5 – 8; inert on chladni	The exponent in z -> z^power + c: 2 is the classic set, higher whole powers add lobes, and a fractional power tears along the negative real axis.	shape
interior	0	escape_time 0 – 1; inert on chladni	How much light the set itself emits; 0 is the textbook black interior.	colour
trap_radius	0.5	escape_time 0 – 2; inert on chladni	How far the orbit trap sits from the origin — the circle’s radius, the line’s offset, the point’s and the cross’s distance. Inert with no trap.	shape
trap_rotate	0	escape_time 0 – 1; inert on chladni	Turns the orbit trap about the origin, in whole turns. Inert on a circle and with no trap.	motion
color_span	1	0 – 4	How much of the palette the field’s level covers; 0 is one flat colour.	colour, main
color_center	0	-1 – 1	Shifts which part of the palette the field’s level starts from.	colour
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.	light, main
hue	0	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.	colour, main
zoom	1	0.25 – 4	Scales the whole scene about its centre; above 1 fills more of the frame.	shape
pan_x	0		Slides the whole scene sideways, in the scene’s own units rather than pixels.	shape
pan_y	0		Slides the whole scene vertically, in the scene’s own units rather than pixels.	shape
saturation	1	0 – 1	Pulls the scene’s colour toward grey; 0 is fully desaturated, 1 is the palette’s own.	colour
palette_mix	0	0 – 1	Crossfades from the preset’s palette to its second one; 0 is the first, 1 the second.	colour
palette_contour	0	0 – 1	Draws a line at each band edge when the palette is stepped; 0 draws none.	colour
palette_contour_ink	0	0 – 1	Where along the palette an ink contour takes its colour; unread by the two black styles.	colour
