Interface SunSample

A single sampled sun position with its direction on the dome.

interface SunSample {
    aboveHorizon: boolean;
    altitude: number;

Properties

aboveHorizon: boolean

altitude: number

Degrees above the horizon (negative below).

azimuth: number

Degrees clockwise from true north (0–360).

declination: number

Solar declination in degrees (for sun-path construction / debugging).

dir: Enu

Unit direction on the dome (below-horizon samples have u < 0).

equationOfTime: number

Equation of time in minutes (apparent − mean solar time).

time: Date
