Motivation
Popularity of existing urban environments in virtual reality simulations
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
5
Problem
Individual and manual Complicated, time-consuming and expensive
High detailed models Require great bandwidth and high hardware specs
Produced data has limited usability Only geometry, no semantics
6
Problem
Semi-automatic methods
Integrates real world data sources
Most don’t have enough detail…
Could benefit from empirical contributions…
Procedural Modeling
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?
8
Objectives
Features
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
Main Goal:
Create a collaborative solution for virtual urban environment recreation for landscape
simulation
