Struct LightSourceDirectional 

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

Borrowed projection of IfcLightSourceDirectional: parallel rays with an orientation but no position.

Implementations

impl<'m, 's> LightSourceDirectional<'m, 's>

pub fn light_source(&self) -> LightSource<'m, 's>

The inherited IfcLightSource colour and intensity attributes.

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

The Orientation attribute: a mandatory IfcDirection reference.

Returned as an id, not a vector. Resolving and normalizing a direction is geometry-resource work; this crate references representation items without importing geometry types.
