}

Milkyway draw-style parameters. All fields have defaults — JSON {"mode":"milkyway"} alone works. Lines render as star chains over a soft nebula ribbon tinted with the series line_color (that ribbon is what keeps multiple series distinguishable); star counts stay uniform per arc length, while star colors stay physical (blackbody locus, population mix follows the clump field).

Fields

star_density: f32

Stars per 100 px of arc length. Default 14.0.

ribbon_width_px: f32

Nebula ribbon full width, in px (“두께”). Default 14.0.

ribbon_intensity: f32

Ribbon brightness 0..1 — how strongly the series-colored haze shows behind the stars. Default 0.30 (thin).

star_scale: f32

Global star size multiplier. Default 1.0.

star_brightness: f32

Global star brightness multiplier. Default 1.0.

spread_px: f32

Perpendicular star scatter σ from the path, in px. Larger reads more like a loose cluster, smaller tracks the data tighter. Default 2.5.

structure_scale: f32

Multiplier on the style’s px-denominated STRUCTURE constants — the clump/population noise wavelength (90 px base) and binary-companion separation. This is what keeps the star texture resolution-invariant: export scaling multiplies it (and divides star_density) automatically; hosts that render a larger physical canvas (dpr > 1) should do the same. Default 1.0.

faint_bias: f32

Luminosity-function slope: the exponent of the brightness power law. Higher → a larger fraction of faint small stars per bright anchor (real fields sit faint-heavy). Sensible range ~1.5..6. Default 3.0.

glow: f32

Decoration glow (line-light bloom) gain on axes/ticks/labels/titles. 0 disables the bloom. Default 0.55.

nebula: f32

Nebula cloud intensity multiplier for the space backdrop. 1.0 is the legibility-calibrated default (peak ≤ ~12/255 per channel); the painter keeps the panel center cleanest at any setting. Default 1.0.

dust: f32

Background dust-star density multiplier (1 px, far dimmer than data stars). 0 removes the dust. Default 1.0.

planet_rim: f32

Planet atmospheric rim-glow strength (the series color’s only appearance on scatter planets). Default 0.34.

seed: u32

Global seed. Same (config, data) → identical output. Default 0.

Implementations

impl MilkywayOptions

pub const PARAM_SPECS: &'static [StyleParamSpec]

Parameter metadata for hosts — see StyleParamSpec. A model test pins each default to Default, so the two cannot drift.
