I have blogged about this product before and now Microsoft has announced
Microsoft Corp. today announced updates to its Photosynth technology that enable commercial use through integration with Microsoft Virtual Earth. The Photosynth integration into Virtual Earth signifies the first release designed to enable businesses to use Photosynth in commercial applications.
Photosynth software analyzes digital photographs and generates a 3-D model by “stitching” the photos together. These models, or “synths,” can now be viewed using Silverlight technology across multiple platforms. Virtual Earth brings together features, functionality and content that help consumers, businesses, citizens and governments bring location to life. It helps businesses and governments share location-based information, build better connections with consumers or citizens, and helps organizations make better operational decisions. With the integration of Photosynth into Virtual Earth customers will be able to create detailed 3-D views of anything from places to products and from hotels to homes.
