System: lsystem

Structural

Parameter	Default	Range	What it does	Group
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.	colour
mirror_order	1	flat 1 – 12; inert on space, flat endless, space endless	Repeats a flat L-system this many times around the centre; 1 draws it once.	shape

Modal

Parameter	Default	Range	What it does	Group
visible_depth	1	flat 1 – 7; space 1 – 7; inert on flat endless, space endless	Which recursion generation is drawn, counted from 1 and capped at max_depth; a fraction floors to the generation below it, and anything under 2 draws the first.	shape, main
rotation	0	flat 0 – 6.2831855; flat endless 0 – 6.2831855; inert on space, space endless	Turns a flat figure in its plane, in radians.	motion
hue	0.3	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.	colour, main
hue_spread	0	0 – 1	How far along the palette the colour travels from one end of the figure to the other.	colour
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
draw_progress	1	flat 0 – 1; space 0 – 1; inert on flat endless, space endless	How much of a fixed L-system is drawn, from its first segment: 0 none, 1 all of it.	motion
thickness	1.8	0.5 – 12	Stroke width: on a flat figure in the shared line units, on a space figure in pixels at the focal plane, wider nearer and narrower farther.	shape, main
scale	1	flat 0.1 – 2; flat endless 0.1 – 2; inert on space, space endless	Scales a flat figure about its centre; a space figure is sized by the camera’s distance instead.	shape
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.	light, main
glow	1	0 – 4	Brightness of the halo around each stroke, on top of the stroke itself.	light, main
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.	light
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
stroke_blend	0	flat 0 – 1; flat endless 0 – 1; inert on space, space endless	Moves a flat L-system’s stroke from additive light toward opaque paint, so crossing branches stop brightening.	light
mirror_reflect	0	flat 0 – 1; inert on space, flat endless, space endless	Alternates a flat L-system’s repeats into mirror images rather than plain rotations.	shape
yaw	0	space -3.1415927 – 3.1415927; space endless -3.1415927 – 3.1415927; inert on flat, flat endless	Turns the camera around a space tree, in radians; bind it to a slow clock to orbit.	motion
pitch	0.25	space -1.55 – 1.55; space endless -1.55 – 1.55; inert on flat, flat endless	Raises the camera above a space tree, in radians; negative looks up from below.	motion
distance	3.5	space 1.5 – 8; space endless 1.5 – 8; inert on flat, flat endless	How far the camera sits from a space tree’s centre; nearer makes the tree larger and exaggerates the perspective.	motion
fov	0.8	space 0.2 – 2; space endless 0.2 – 2; inert on flat, flat endless	The camera’s vertical field of view onto a space tree, in radians; zoom divides it.	motion
focus	0.5	space 0 – 1; space endless 0 – 1; inert on flat, flat endless	Where the focal plane sits in a space tree’s depth: 0 at its nearest point, 1 at its farthest.	light, main
aperture	0	space 0 – 24; space endless 0 – 24; inert on flat, flat endless	The blur of a space tree’s far side, in pixels; branches nearer than the focal plane blur more, up to the tier’s cap. 0 keeps every branch sharp, and wider costs fill.	light, main
fog	0	space 0 – 1; space endless 0 – 1; inert on flat, flat endless	Fades a space tree toward black with depth: at 1 its farthest point is black and its nearest keeps its light. 0 is off.	light
solid	0	space 0 – 1; space endless 0 – 1; inert on flat, flat endless	1 paints a space tree’s near branches over its far ones, so it reads as an object and crossings stop brightening; 0 is the additive glow. Solid sorts every segment by depth each frame.	light
grow	20	flat endless 0 – 120; space endless 0 – 120; inert on flat, space	How fast an endless figure grows, in draw steps a second; bind it to onset to make it surge.	motion, main
tail	0.5	flat endless 0 – 1; space endless 0 – 1; inert on flat, space	The oldest fraction of an endless figure’s trail that fades out; 0 keeps every segment at full light until it is dropped.	light
follow	0.3	flat endless 0.05 – 3; space endless 0.05 – 3; inert on flat, space	How slowly the view follows an endless figure’s growing tip, in seconds: short keeps the tip near the centre, long lets it lead and glides after a branch’s jump.	motion
