How to display mouse cursor coordintes on Scene(not Map)?

I didn't find any code example. I've found how to display coordinates on Map(Show Mouse Coordinates | ArcGIS for Developers ). But it seems it doesn't fit for Scene

You can use the Scene.ScreenToBaseSurface method from a MouseMove event: https://developers.arcgis.com/net/latest/wpf/api-reference/html/M_Esri_ArcGISRuntime_UI_Controls_SceneView_ScreenToBaseSurface.htm

There's also a more accurate ScreenToLocationAsync method that takes data in layers into account, but this is a lot slower and not recommended to be used on a mouse move event.

It's basically identical to the sample you linked to, but with sceneview and the ScreenToBaseSurface method instead of ScreenToLocation.

my code sample that works. if somebody is interested in

private async void MySceneView_MouseMove(object sender, MouseEventArgs e)
{

if (MySceneView.GetCurrentViewpoint(ViewpointType.BoundingGeometry) == null)
return;

//get screen coordinates

System.Windows.Point screenPoint = e.GetPosition(MySceneView);
ScreenCoordsTextBlock.Text = string.Format("Screen Coords: X = {0}, Y = {1}", screenPoint.X, screenPoint.Y);

//get geographical coordinates

MapPoint mapPoint = new MapPoint(0,0,0);

mapPoint = await MySceneView.ScreenToLocationAsync(screenPoint);

MapCoordsTextBlock.Text = string.Format("Map Coords: X = {0}, Y = {1}, Z = {2}",
Math.Round(mapPoint.X, 4), Math.Round(mapPoint.Y, 4));

}

I'd recommend you be very careful with running async code in an event as frequent as mouse-move. The async get location call is actually quite expensive, so it could severely affect rendering performance. I'd recommend using the synchronous ScreenToBaseSurface method instead in this event, and not run the high-accuracy one until after the mouse stopped moving, as well as avoid doing it while SceneView.IsNavigating==true (I doubt it's really that useful while navigating anyway)
