    • A SEAMLESS GIS/GOOGLE WORKFLOW3D Buildings•  Using Sketch Up to build the building model•  Save the file with KMZ format (tour video will be zipped in the final KMZ file)•  If you still want to use 3D Warehouse to save loading time, save the placemarks, tours, page info, and polygons in a kml file. But remember to check each placemark with the model you already upload to 3D Warehouse.3D Terrian•  Using ArcGIS Scene to create a TIN on a topo layer. (import the base .shp contour file first)•  Import the imaginary file (e.g. an old map), make show the two layers are on the same scale and hopefully the exact same matching top-down location•  Drape the new layer by right click on PropertiesàBase Height Tabàobtain height info from the TINàApplyàPreviewàOKàExport Scene in 3Dà”Hello, Earth!” VRML 3D Terrian

In the Berlin•  Base Heights tabàobtain heights from grid dataàApply address several visualization techniques. Photorealistic Visualization In the context of tourism, entertainment, or public participation a high d is required (Fig. 3). For instance, if the aim is to give a realistic imVRML Authoring and Crafting environment, the quality of a 3D visualization is directly related to the virtual city model and the actual result after implementation of the plann•  A format that can contain 3D models like COLLADA(sketchup exportenable real-time rendering of large-scale 3D city models, rates. geo To .dae file) to be reduced in order to guarantee high and constant frame their For geometry or texture related optimization and multiresolution algorithm•  View: Free WRL: http://freewrl.sourceforge.net/ can be applied to achieve real-time rendering even for complex virtual Buchholz & Döllner 2005b, Willmott et al. 2001).•  Edit: Seamless 3D: http://www.seamless3d.com/download/•  Mashlab: http://meshlab.sourceforge.net/•  Other: http://www.web3d.org/x3d/vrml/tools/viewers_and_browsers/•  http://www.ai.sri.com/geovrml/Photo Source ”Berlin-3D”from RSS GmbH, Potsdam/München, DRL Berlin-Adlershof, and 3D Geo GmbH, Potsdam
