If you're developing using Insight3D or any of our components, I'm sure you've come across our developer network: ADN. One area of ADN that is gaining momentum is the Code Exchange, where AGI users and employees share code samples. Recently, I posted two Insight3D examples. A Point in Polygon Test example that shows how to determine if a point on the globe is inside a polygon on the globe. The other example, Drawing Shapes on the Globe, shows how to allow the user to draw polylines and polygons on the globe similar to 3D object editing in STK.
