I'm trying to make a animation in WPF using data bindings. I 'm using MatrixAnimationUsingPath to let a shape follow a path. the path are representet in my viewModel as a array; Point[]. How can I bind my point property in my viwmodel so I can use it with MatrixAnimationUsingPath.

```
<Storyboard>
   <MatrixAnimationUsingPath Storyboard.TargetName="MyMatrixTransform" 
     Storyboard.TargetProperty="Matrix" DoesRotateWithTangent="True" 
     Duration="0:0:5" RepeatBehavior="Forever">
       <MatrixAnimationUsingPath.PathGeometry>
           <PathGeometry>
               // WHAT TO PUT HERE!
           </PathGeometry>
       </MatrixAnimationUsingPath.PathGeometry>
   </MatrixAnimationUsingPath>
</Storyboard> 

```

I have been able to create a path from the points, using a value converter, but I'm not able to use the path in the MatrixAnimationUsingPath.

```
<Path Name="MyPath" StrokeThickness="2" Data="{Binding Path=Points, Converter={StaticResource ResourceKey=PointsToPathConverter}}">

```

Added after comment:

I havn't workt so mush with value converters berfore. the converter I used, I did find online. Hos can I modify it?

```
[ValueConversion(typeof(Point[]), typeof(Geometry))]
public class PointsToPathConverter : IValueConverter
{
    #region IValueConverter Members

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        Point[] points = (Point[])value;
        if (points.Length > 0)
        {
            Point start = points[0];
            List<LineSegment> segments = new List<LineSegment>();
            for (int i = 1; i < points.Length; i++)
            {
                segments.Add(new LineSegment(points[i], true));
            }
            PathFigure figure = new PathFigure(start, segments, false); //true if closed
            PathGeometry geometry = new PathGeometry();
            geometry.Figures.Add(figure);
            return geometry;
        }
        else
        {
            return null;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }

    #endregion
}
