Struct PointLight

Source

pub struct PointLight {
    pub position: EntityId,
    pub radius: f64,
    pub attenuation: Attenuation,
}

Expand description

Where a light sits and how it falls off.

Position, radius and attenuation are not independent knobs: they together describe one point emitter, and every entity carrying one carries all three. Grouping them keeps the spot-light signature honest rather than a seven-argument list where two adjacent f64 parameters invite transposition.

Fields§

§position: EntityId

Position: an IfcCartesianPoint.

§radius: f64

Radius: a positive length.

§attenuation: Attenuation

The three attenuation coefficients.
