Fastest way to georeference image and add it to globe

Hi,

I need to create an animation from sequence of .jpg images in Globe. When new image is added, old one should be deleted. Images aren't georeferenced, but I have 4 points indicating where they should be placed.

I tried the following:

public partial class ArcGISHostControl : UserControl

{

Dictionary<string, ILayer> _mainElementRepository;

string workspace = "C:\\temp\\";

IWorkspaceFactory wpf;

IRasterWorkspace rasterworkspace;

public ArcGISHostControl()

{

InitializeComponent();

_mainElementRepository = new Dictionary<string, ILayer>();

AddBaseLayer(); //adds base maps

wpf = new RasterWorkspaceFactory();

raswp = wpf.OpenFromFile(workspace, 0) as IRasterWorkspace;

}

private string AddNewImage(IPointCollection sourcePoints, IPointCollection targetPoints, string file, string oldID)

{

string id = generateID();

IRasterLayer layer = GeoreferenceImage(file, sourcePoints, targetPoints);

axGlobeControl.Globe.AddLayerType(layer as ESRI.ArcGIS.Carto.ILayer, esriGlobeLayerType.esriGlobeLayerTypeDraped, true);

_mainElementRepository.Add(id, layer);

DeleteObject(oldID);

return id;

}

private IRasterLayer GeoreferenceImage(string file, IPointCollection sourcePoints, IPointCollection targetPoints)

{

IRasterDataset2 rasterDataset;

rasterDataset = rasterworkspace.OpenRasterDataset(file) as IRasterDataset2;

IRasterGeometryProc rasterPropc = new RasterGeometryProcClass();

IRaster raster = rasterDataset.CreateFullRaster();

rasterPropc.Warp(sourcePoints, targetPoints, esriGeoTransTypeEnum.esriGeoTransProjective, raster);

rasterPropc.Register(raster);

IRasterLayer layer = new RasterLayerClass();

layer.CreateFromRaster(raster);

return layer;

}

public void DeleteImage(string id)

{

ILayer forDeletion;

if (_mainElementRepository.TryGetValue(id, out forDeletion))

{

axGlobeControl.Globe.GlobeDisplay.Scene.DeleteLayer(forDeletion);

_mainElementRepository.Remove(id);

}

Problem is that this is very slow, and causes GUI to become nonresponive.

Is there a better way to do this?
