Struct LightingBody 

pub struct LightingBody {
    pub radius: f64,
    pub position: Qty3<dyn Dimension<Kind = dyn Kind, T = Z0, L = PInt<UInt<UTerm, B1>>, N = Z0, Th = Z0, M = Z0, J = Z0, I = Z0>, RootInertial>,
    pub distance: f64,
    pub half_angle: f64,
}

Apparent parameters of a celestial body as seen from the observer.

position carries Position<RootInertial>: the lighting state is always computed against root-inertial source positions (Sun / Moon / Earth at the simulation root), so the field is statically tagged with the root-inertial phantom. A consumer that holds a body’s Position<IntegrationFrame> cannot subtract it from LightingBody.position without going through the typed integration-origin shift first (RF.10).

Fields

radius: f64

Mean equatorial radius (m).

position: Qty3<dyn Dimension<Kind = dyn Kind, T = Z0, L = PInt<UInt<UTerm, B1>>, N = Z0, Th = Z0, M = Z0, J = Z0, I = Z0>, RootInertial>

Position of the body relative to the observer, in the simulation’s root inertial frame (m).

distance: f64

Distance from observer to body (m).

half_angle: f64

Apparent angular half-angle of body disk (rad).
