Three-dimensional (3D) city building models with its related information is an important part in the construction of Digital City and Digital Earth, and has been becoming a kind of staple resources on the web. Based on the characteristics of 3D building model, a service-oriented architecture and Web service technology for 3D city building models is discussed. A structure detail based building model...
3D city building models with their related information have increasingly become an important part and have a wide range of application areas in construction of digital city and digital earth, In view of the representation of 3D building model in hierarchy, an abstract of 3D building model based on structure details is studied, and a novel representation approach named 3D transparent building model...
“How do the rescue helicopters find out an optimized path to arrive at the site of a disaster as soon as possible?” or “How are the flight procedures over mountains and plateaus simulated?” and so on. In this paper a script language on spatial moving objects is presented by abstracting 3D spatial moving objects’ behavior when implementing moving objects simulation in 3D digital Earth scene, which...
