  1. Integrating Virtual Environmentand GIS for 3D Virtual CityDevelopmentand Urban Planning Bin Chen, Fengru Huang, Yu Fang Peking University

  2. Content • Introduction • Virtual World Technology • Integrate VW with GIS • A Practice of VW Based Virtual City • Conclusions and Future Work

  3. Introduction • Recently innovative technologies offer different ways of modelling andrepresenting urban informationwith real-time interaction over the Internet. • 3 generations of virtual city technology • Web listing by text, image and video • "Flat" cities by 2D map • 3D visualization virtual city

  4. Virtual World Technology • Virtual World is a multi-user 3D creative platform based on virtual environment • Users immersed into virtual environment by avatars • Online collaborative authoring and application development • Different from traditional virtual reality

  5. Features of Virtual World • Virtual reality environment • Virtual terrain and virtual atmosphere • Dynamics simulation • 3D authoring platform • Network oriented 3D modelling • Script language • interact among virtual environment, avatars and 3D models • communicate with outer process • Avatar system • Instant messaging

  6. Virtual World Technology • As a general purpose development platform, VW can be used to support applications from a wide range of fields • Online entertainment, virtual communities • Virtual education and trainning • Scientific visulization • Virtual tour, urban planning • Emergency response and drill • Facility Management

  7. Virtual World Technology • VWs are becoming the new generation of mainstream Internet contents followed after text, image, audio and video

  8. Integrate VW with GIS • Extending geodata model by virtual reality • Integrate geodata with 3D models • Support realtime update and modification of virtual scenes • Online multi-user collaborative workflow • Emphasize collaborative interaction of multi-user • Increase performance of user-avatar interaction with virtual environment • New method of mapping between 2D geodata and 3D models

  9. Integrate VW with GIS • Develop human-scale GIS application • Considering features of small scale space • Enrich general purpose development platform of VW • Combined with geoprocess model library • Communicate with outer geodatabase and workflow

  10. VW Based Virtual City • Advantages includes • Network oriented • Fast and low-cost 3D modeling • Multiple plans show • Multi-user collaborative evaluation • Realtime plan modification

  11. A Practice of VW Based Virtual City • The project integrate the real Shunde Industrial Design City,which hosted in Guangdong of South China, with avirtual environment by geographic mapping and 3D virtualmodeling. • Based on VW server of Opensimulator • About 4 square kilos

  12. A Practice of VW Based Virtual City • A joystick allows the user avatar to fly-through the 3D model in realtime • have a look from different perspectives at complextopographic structures as well as the smallest architecturaldetails.

  13. A Practice of VW Based Virtual City • Based on the 3D visualization of the real architecture andlandscape of Shunde Industrial City, users of different levelsand objectives can have varies activities and experiences invirtual environment • including interactive mapping andcollaborative modelling, solid, geometric modellingphotospatial panoramic views, and multi-user virtual worlds. • For urban planning, the planners can construct or movelandscape elements • such as roads, buildings, plants,sculptures, bridges, water, etc • based on their observationand consideration in the virtual city collaboratively.

  14. Conclusions and Future Work • Applications based on virtual world are becomingpopular, virtual city and urban planning is a typical case • Extending VW with GIS will make virtual city more powerful by many aspects including immersive virtual environment and collaborative interaction • Further work will focus on the complete design and development of virtual applications of urban planning

  15. End • Thanks for your attention!
