Struct LightDistributionData 

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

Borrowed projection of IfcLightDistributionData: one main-plane angle and the intensities measured across the secondary angles in that plane.

SecondaryPlaneAngle and LuminousIntensity are parallel lists: entry i of one corresponds to entry i of the other. The schema does not state that pairing as a WHERE rule, so Self::samples enforces it here instead of letting a caller zip two mismatched lists and silently truncate.

Implementations

impl<'m, 's> LightDistributionData<'m, 's>

pub fn main_plane_angle(&self) -> StyleResult<f64>

The MainPlaneAngle attribute, an IfcPlaneAngleMeasure.

Signed and unbounded: unlike the spot cone angles this is a plain IfcPlaneAngleMeasure, not a positive one, so negative angles are valid authored data and are not rejected.

pub fn secondary_plane_angles(&self) -> StyleResult<Vec<f64>>

The SecondaryPlaneAngle attribute: LIST [1:?] OF IfcPlaneAngleMeasure.

pub fn luminous_intensities(&self) -> StyleResult<Vec<f64>>

The LuminousIntensity attribute: LIST [1:?] OF IfcLuminousIntensityDistributionMeasure (candela per lumen under the SI default).

pub fn samples(&self) -> StyleResult<Vec<(f64, f64)>>

The (secondary plane angle, luminous intensity) pairs.

Fails with a typed crate::StyleError::InvalidValue when the two lists differ in length, because a photometric table with a missing intensity is corrupt rather than partially usable.
