A collaborative environment for urban landscape simulation

  1. 1. Pedro Brandão Silva pedro.brandao.silva@fe.up.ptAntónio Coelho acoelho@fe.up.ptRosaldo J. F. Rossetti rossetti@fe.up.pt A Collaborative Environment for Urban Landscape Simulation 1
  2. 2. Presentation Outline• Motivation• Problem• Objectives• Related Work• Simulation Platform• Results• Conclusion & Future Work 2
  3. 3. Motivation Popularity of existing urban environments in virtual reality simulations 3
  4. 4. Motivation Real-time modeling virtual urban environments as an end in itself  Architecture & Urban Planning  Police, Firefighting, Health  Resident Opinion As a means to obtain virtual urban models for  Advertising  Virtual Tourism  Training  Education & Research 4
  5. 5. ProblemIndividual and manual  Complicated, time-consuming and expensiveHigh detailed models  Require great bandwidth and high hardware specsProduced data haslimited usability  Only geometry, no semantics 5
  6. 6. ProblemProcedural Modeling Semi-automatic methods Integrates real world data sources  Most don’t have enough detail… Could benefit from empirical contributions… 6
  7. 7. Problem How to employ procedural modeling techniques, integrating real world data sources and user contributions, for the generation of virtual urban environments for landscape simulation? 7
  8. 8. Objectives Main Goal: Create a collaborative solution for virtual urban environment recreation for landscape simulationFeatures  Allows users to visualize, navigate and interact with large areas of urban terrain  Use real world data and randomness as starting point  Procedural modeling to generate a tridimensional city model in real-time  Allow collaboration between users for GIS data refinement 8
