    Properties

    betaR?: [number, number, number]

    Rayleigh extinction (per world unit) at the three reference wavelengths.

    betaM?: number

    Mie extinction (per world unit).

    betaO?: [number, number, number]

    Ozone (Chappuis-band) absorption coefficient.

    sunIntensity?: number

    Sun radiance at top of atmosphere, HDR units.

    groundAlbedo?: [number, number, number]

    Ground albedo used by the bounce term.

    rE?: number

    Planet surface radius (R_E).

    rA?: number

    Atmosphere top radius (R_A).

    hRayleigh?: number

    Rayleigh scale height.

    hMie?: number

    Mie scale height.

    ozoneCenter?: number

    Altitude of peak ozone density.

    ozoneHalfWidth?: number

    Half-width of the ozone tent profile.

    groundBounceH?: number

    Altitude over which the ground bounce fades to nothing.

    groundBounceStrength?: number

    Global gain on the ground-bounce in-scatter.

    groundRoughness?: number

    Oren-Nayar slope σ used by the ground bounce.

    radius: number

    Surface radius, in world units.

    atmosphereHeight?: number

    Atmosphere thickness above the surface, in world units. Defaults to 16 % of the planet radius — a stylized, visibly chunky shell.
