您可以向 3D 地图中添加多边形。
以下代码示例演示了如何使用 Polygon
结构体添加 3D 多边形并将其放置在 3D 空间中。
Swift
Map(mode: .hybrid) {
Polygon(
outerCoordinates: [
.init(latitude: 37.7749, longitude: -122.4194, altitude: 0),
.init(latitude: 37.7740, longitude: -122.4184, altitude: 0),
.init(latitude: 37.7750, longitude: -122.4174, altitude: 0),
]
)
}
