您可以向 3D 地图添加相机路径动画,为用户提供更具沉浸感的体验。相机路径动画可以飞往、环绕或 组合,以将相机动画到地图上的某个点,包括指定其 海拔高度 。
飞往
以下代码示例演示了如何通过调用
flyCameraTo
方法,将相机动画到 3D 地图上的
特定点。
// Add imports and define constants
import com.google.android.gms.maps3d.model.latLngAltitude
const val EMPIRE_STATE_BUILDING_LATITUDE = 40.748233
const val EMPIRE_STATE_BUILDING_LONGITUDE = -73.985663
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.flyCameraTo(
flyToOptions {
endCamera = camera {
center = latLngAltitude {
latitude = EMPIRE_STATE_BUILDING_LATITUDE
longitude = EMPIRE_STATE_BUILDING_LONGITUDE
altitude = 212.0 // in meters
}
heading = 34.0 // bearing in degrees
tilt = 67.0 // relative to vertical
range = 750.0 // distance away from the focal point in meters
roll = 0.0 // roll relative to horizontal
}
durationInMillis = 2_000
}
)
环绕
以下代码示例演示了如何通过调用
flyCameraAround
方法,将相机动画到 3D 地图上的
特定点周围。
// Add imports and define constants
import com.google.android.gms.maps3d.model.latLngAltitude
const val EMPIRE_STATE_BUILDING_LATITUDE = 40.748233
const val EMPIRE_STATE_BUILDING_LONGITUDE = -73.985663
...
// Add to the onMap3DViewReady method, after the googleMap3D object has been initialized
googleMap3D.flyCameraAround(
flyAroundOptions {
center = camera {
center = latLngAltitude {
latitude = EMPIRE_STATE_BUILDING_LATITUDE
longitude = EMPIRE_STATE_BUILDING_LONGITUDE
altitude = 212.0
}
heading = 34.0
tilt = 67.0
range = 750.0
roll = 0.0
}
durationInMillis = 5_000
rounds = 1.0 // Number of rotations - can be fractional
}
)
