On the 9th of April an update for the version 6.2 of the Virtual Earth AJAX MapControl was launched and along with it came a new version of the VE 3D-Control which brings performance enhancements but also lots of new features which are described in more detail on the Virtual Earth 3D Team Blog.
Amongst others you can now walk into your custom 3D models again. This feature had been there before but was silently disabled in a previous release. Now you can stand inside your house and have a look at the miserable weather outside again :-). Have a look for yourself.
From the new features I find the custom Digital Elevation Model (DEM) most significant. I’m not sure if “Bunny-Valley” will now become one of the wonders of the world but it certainly demonstrates the new capabilities.
