Polygons on a 3D map

The following code sample demonstrates how to add a 3D polygon and position it in 3D space by calling the addPolygon method. To use this code sample, follow the instructions in Setup and Add a 3D map to your app to set up your Android Studio project with a basic 3D map. Then, add the following code to the MainActivity.kt file:

// Add imports and define variables import com.google.android.gms.maps3d.model.LatLngAltitude import com.google.android.gms.maps3d.model.polygonOptions val zooOutline = """  39.7508987, -104.9565381  39.7502883, -104.9565489  39.7501976, -104.9563557  39.7501481, -104.955594  39.7499171, -104.9553043  39.7495872, -104.9551648  39.7492407, -104.954961  39.7489685, -104.9548859  39.7484488, -104.9548966  39.7481189, -104.9548859  39.7479539, -104.9547679  39.7479209, -104.9544567  39.7476487, -104.9535341  39.7475085, -104.9525792  39.7474095, -104.9519247  39.747525, -104.9513776  39.7476734, -104.9511844  39.7478137, -104.9506265  39.7477559, -104.9496395  39.7477477, -104.9486203  39.7478467, -104.9475796  39.7482344, -104.9465818  39.7486138, -104.9457878  39.7491005, -104.9454874  39.7495789, -104.945938  39.7500491, -104.9466998  39.7503213, -104.9474615  39.7505358, -104.9486954  39.7505111, -104.950648  39.7511215, -104.9506587  39.7511173, -104.9527187  39.7511091, -104.9546445  39.7508987, -104.9565381""".trimIndent()  .split("\n")  .map { line -> line.split(",").map { it.trim().toDouble() } }  .map { coords ->  latLngAltitude {  latitude = coords[0]  longitude = coords[1]  altitude = 0.0  }  } val zooPolygonOptions = polygonOptions {  outerCoordinates = zooOutline  fillColor = Color.argb(70, 255, 255, 0)  strokeColor = Color.GREEN  strokeWidth = 3.0  altitudeMode = AltitudeMode.CLAMP_TO_GROUND } val zooPolygon = googleMap3D.addPolygon(zooPolygonOptions) ... // Add to the onMap3DViewReady method, after the googleMap3D object has been initialized googleMap3D.setCamera(  camera {  center = latLngAltitude {  latitude = 39.748477  longitude = -104.947575  altitude = 1610.0  }  heading = 290.0  tilt = 47.0  range = 2251.0  } )
