Description
Whether extruded geometries are lit relative to the map or viewport.
Type
enum
Default Value
viewport
Supported Values
map - The position of the light source is aligned to the rotation of the map.
光源的位置与地图的旋转对齐
viewport - The position of the light source is aligned to the rotation of the viewport.

Expression
Parameters: zoom
Name
position
Description
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).
光源相对于照明(拉伸)几何图形的位置，在[r径向坐标，方位角，p极角]中，其中r表示从对象的底部的中心到其光的距离，a表示光相对于0°的位置(当light.anchor设置为‘viewport时为0°时，对应于视口的顶部，或者当light.anchor设置为map`时为0°，对应于正北，度顺时针进行)，p表示光的高度(从0°，正上方，到180°，正下方)。
