Properties of the sun.
Member Data Documentation
◆ azimuth
| optional double osi3::EnvironmentalConditions::Sun::azimuth = 1 |
Azimuth of the sun, counted counterclockwise.
0 pointing north. If north is not explicitly defined via osi3::GroundTruth::proj_string, then north is pointing in y-axis direction. The default orientation (x, y, z) is easting, northing, up [1]. The point of observation is defined to be the global coordinate system's origin.
- Note
- 0: north; +pi/2: west; pi: south, 3/2 pi: east.
Unit: rad
The preferred angular range is [0, 2pi].

◆ elevation
| optional double osi3::EnvironmentalConditions::Sun::elevation = 2 |
Solar elevation angle.
The elevation angle is positive when the sun is above the xy-plane, negative when the sun is below the xy-plane. The point of observation is defined to be the global coordinate system's origin.
- Note
- 0: xy-plane; +pi/2: zenith; -pi/2: nadir.
Unit: rad
The preferred angular range is [-pi/2, +pi/2].
◆ intensity
| optional double osi3::EnvironmentalConditions::Sun::intensity = 3 |
Illuminance of the sun, direct sunlight is around 100000 lx.
Unit: lx
- Rules
- is_greater_than_or_equal_to: 0
