    Scalable content for urban applications
    (2011) Juan Diego Toro; Pablo Figueroa
    We present an application that allows the acquisition of 3D models in an open format that adjust to the device's requirements and specifications. By defining a format in X3D to describe each one of the kinds of objects we have considered as part of an urban model, such as blocks, buildings, cars, pedestrians, streetlights, and massive transportation, among others. This way, the application that requests the urban model can manipulate each of its components independently. The model stores not only graphic representation of objects, but also animation and setup of a certain scene. The application stores in the database scenes as independent objects that can be requested by applications. The application can deliver the same model in different LOD (level of detail) according to the device or application realizing the request.
