Light¶
The global light source.
anchor¶
Optional enum. Possible values: map, viewport. Defaults to "viewport".
Whether extruded geometries are lit relative to the map or viewport.
map: The position of the light source is aligned to the rotation of the map.viewport: The position of the light source is aligned to the rotation of the viewport.

position¶
Optional array. Defaults to [1.15,210,30]. Supports interpolate expressions. Transitionable.
Position of the light source relative to lit (extruded) geometries, in [r radial coordinate, a azimuthal angle, p polar angle] where r indicates the distance from the center of the base of an object to its light, a indicates the position of the light relative to 0° (0° when light.anchor is set to viewport corresponds to the top of the viewport, or 0° when light.anchor is set to map corresponds to due north, and degrees proceed clockwise), and p indicates the height of the light (from 0°, directly above, to 180°, directly below).

intensity¶
Optional number in range [0, 1]. Defaults to 0.5. Supports interpolate expressions. Transitionable.
Intensity of lighting (on a scale from 0 to 1). Higher numbers will present as more extreme contrast.
