The latest release of ArcGIS Explorer includes a host of enhancements to the API, creating new opportunities for custom task developers. The custom task framework genuinely differentiates ArcGIS Explorer from other virtual globes, allowing users to plug in custom functionality directly into the main application. The most notable of the API enhancements are changes to the View3D class. This class controls the main viewing window in ArcGIS Explorer (the window which displays the globe). New methods and events on the View3D class now allow developers to render OpenGL graphics on top of the view. Someone has also posted a video at YouTube showing wind vectors drawn using OpenGL.
