Hello,

I'm a beginner on using ArcGis runtime V100 framework , and while i was looking at the tutorials i 've created a map using the framework but i didn't find ho to create a scenview can any one tell me how to do that or explain it more for me thanks a lot

Hi and welcome!

Have you looked to Display a scene—ArcGIS Runtime SDK for .NET | ArcGIS for Developers? Hopefully that will give you enough information to get started.

If you created a MapView and a Map already, it's pretty much identical, except replace the word "Map" with "Scene", so you'll be creating a SceneView instead of a MapView, and you'll be assigning a Scene instead of a Map to the SceneView.Scene property instead of the MapView.Map property.

Hello,

I've already seen it , it didn't help me a lot , and doesn't explain it good for beginners like me , is there a possibility to alter it and make it more clear (step by step)? thanks a lot

but it doesn't show me the scene as in the tutorial and i have an error saying SpatialReference doesn't have a definition for "Wgs84"

Any one can make it clear to me please

thanks a lot

Hi Manel,

I am able to see the 3D scene layer. Below is my code:

XAML:

XAML.cs

=========

public MainWindow()
{
InitializeComponent();
Initialize();
}

private void Initialize()
{

Scene myScene = new Scene(Basemap.CreateTopographic());

ArcGISSceneLayer sceneLayer = new ArcGISSceneLayer(new Uri("http://scene.arcgis.com/arcgis/rest/services/Hosted/Buildings_Brest/SceneServer/layers/0"));
myScene.OperationalLayers.Add(sceneLayer);

// create a new elevation source and add to scene
ArcGISTiledElevationSource elevationSource = new ArcGISTiledElevationSource(new Uri("http://elevation3d.arcgis.com/arcgis/rest/services/WorldElevation3D/Terrain3D/ImageServer"));

myScene.BaseSurface.ElevationSources.Add(elevationSource);

// create a camera and set the initial viewpoint

MapPoint mapPoint = new MapPoint(-4.49779155626782, 48.38282454039932, 62.013264927081764, SpatialReferences.Wgs84);

Camera camera = new Camera(mapPoint, 41.64729875588979, 71.2017391571523, 2.194677223e-314);

Viewpoint initViewpoint = new Viewpoint(mapPoint, camera);

myScene.InitialViewpoint = initViewpoint;

MySceneView.Scene = myScene;

}
}

I noticed sometime it takes time to load the the 3D Scene. Hope that helps. Thanks

Nagma

'SpatialReference.Wgs84' should probably be 'SpatialReferences.Wgs84' (the extra 's' is missing)
