I got an assigment to add photo overlay on ArcGis Scene. Photo is updated after few seconds.
I couldn't find another solution, so I use KMLLayer, in following scenario:
1-create temporary kml file with ground overlay object
2-create KMLLayer with file uri
3-add new layer to scene
4-remove old one
First 3 steps are working smoothly, but when I try to remove old layer, application sometimes crashes (I can reproduce crashing with zooming and panning scene)
Code is bellow.
private async void AddKMLLayer(string kml, string id, string oldid)
{
await AddLayer(kml, id, SearchCompleted, oldid);
}
private async Task AddLayer(string kml, string id, Action<KmlLayer> callback, string oldid)
{
Uri sourceUri = new Uri(Environment.GetFolderPath(_folder + @"\" + id + ".kml");
KmlLayer layer = new KmlLayer(sourceUri);
layer.ID = id;
_arcGISmapWPF.SceneView.IsEnabled = false;
await layer.InitializeAsync();
callback(layer, oldid);//add layer when initialized
}
private void SearchCompleted(KmlLayer layer, string oldid)
{
_arcGISmapWPF.SceneView.Scene.Layers.Add(layer);
_arcGISmapWPF.SceneView.Scene.Layers.remove(oldid);
}
