Struct LightSource 

pub struct LightSource<'m, 's> { /* private fields */ }

Borrowed projection of IfcLightSource: the colour and intensity every light shares, independent of how it is positioned or aimed.

AmbientIntensity and Intensity are both OPTIONAL in all three bundled schemas. An absent value is reported as None, never defaulted to 1.0: choosing a fallback is a renderer policy, and inventing one here would make an unauthored file indistinguishable from one that authored full intensity.

Implementations

impl<'m, 's> LightSource<'m, 's>

pub fn kind(&self) -> StyleResult<LightSourceKind>

The concrete subtype this entity declares.

pub fn name(&self) -> StyleResult<Option<&'m str>>

The Name attribute, when authored.

pub fn light_colour(&self) -> StyleResult<EntityId>

The LightColour attribute: a mandatory IfcColourRgb reference.

pub fn ambient_intensity(&self) -> StyleResult<Option<f64>>

The AmbientIntensity attribute, normalized to [0, 1] when authored.

pub fn intensity(&self) -> StyleResult<Option<f64>>

The Intensity attribute, normalized to [0, 1] when authored.
