System: voxel

Structural

Parameter	Default	Range	What it does	Group
rule	0	0 – 7	Which of the [voxel] rules runs, counting from 0; past the list’s end it runs the last. A change takes effect at the next generation.	shape, main
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.	colour

Modal

Parameter	Default	Range	What it does	Group
step_rate	8	0 – 30	How many generations the automaton runs per second, whatever the frame rate; 0 freezes it.	motion, main
reseed	0	0 – 1	A rise past 0.5 fills one ball of the cube with fresh seeded cells, once per rise; bind an onset or a beat to it.	motion
reseed_radius	0.25	0.05 – 1	The radius of the ball a reseed fills, as a fraction of the cube’s half-side.	shape
cut	0	0 – 1	How much of the cube a section plane hides, so the inside shows: 0.5 cuts it through the centre, 1 hides it all, 0 is off. Only the view is cut; the automaton runs on.	shape, main
cut_yaw	0	0 – 6.2831855	Which way the section plane faces around the cube’s vertical axis, in radians: the side it hides. It turns with the cube, not the camera.	shape
cut_pitch	0	-1.5707964 – 1.5707964	How far the section plane’s hidden side tilts up toward the cube’s top, in radians; negative tilts it down.	shape
shell_gain	0	0 – 4	How strongly the spectrum lights the cube’s radial shells, bass at the centre and treble at the faces; 0 leaves the light as the cells give it.	light
density	1	0 – 8	How strongly the volume absorbs the light behind it, per unit of the cube’s width; 0 is pure additive glow with no front or back.	light, main
trail	0.6	0 – 1	How much of its light a decaying cell keeps at each stage of its decay; 0 draws only the live cells.	light
age_tint	0.3	0 – 1	How far along the palette a cell’s colour travels as it ages; a decaying cell takes the far end.	colour
hue	0	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.	colour, main
hue_spread	0.3	0 – 1	How far along the palette the colour travels from the cube’s centre to its corners.	colour
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.	light, main
key	1	solid 0 – 4; inert on glow	How strongly the key light lights a solid face turned toward it; 0 leaves only the ambient light.	light, main
ambient	0.3	solid 0 – 1; inert on glow	The light every solid face gets whichever way it turns; 1 with no key light draws each face in its own colour.	light
ao	1	solid 0 – 1; inert on glow	How far the cells around a solid face darken its ambient light toward the creases and inner corners; 0 is none.	light
bounce	0	solid 0 – 2; inert on glow	How much light a solid face takes from the live cells in front of it, so a structure glows onto itself; soft, reaching a few cells and through thin walls. 0 is off.	light
light_yaw	-0.6	solid -3.1415927 – 3.1415927; inert on glow	Where the key light stands around the viewer, in radians: 0 behind the camera, positive to its right. It turns with the camera.	light
light_pitch	0.6	solid -1.5 – 1.5; inert on glow	How far above the viewer the key light stands, in radians; negative lights from below. It turns with the camera.	light
yaw	0	-3.1415927 – 3.1415927	Turns the camera around the scene’s volume, in radians; bind it to a slow clock to orbit.	motion
pitch	0.25	-1.55 – 1.55	Raises the camera above the scene’s volume, in radians; negative looks up from below.	motion
distance	3.5	1.5 – 8	How far the camera sits from the centre of the scene’s volume; nearer exaggerates the perspective.	motion
fov	0.8	0.2 – 2	The camera’s vertical field of view in radians; zoom divides it.	motion
focus	0.5	0 – 1	Inert on voxel: depth of field blurs each drawn primitive, and the march draws none.	light, main
aperture	0	0 – 24	Inert on voxel: depth of field blurs each drawn primitive, and the march draws none.	light, main
fog	0	0 – 1	Fades the volume toward black with depth: at 1 the cube’s farthest point is black and its nearest keeps its light. 0 is off.	light
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
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
