Modeling the Appearance and Behavior of Urban Spaces

16 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

Urban spaces consist of a complex collection of buildings, parcels, blocks and neighborhoods interconnectedby streets. Accurately modeling both the appearance and the behavior of dense urban spaces is a significantchallenge. The recent surge in urban data and its availability via the Internet has...

Building Reconstruction using Manhattan-World Grammars

14 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

We present a passive computer vision method thatexploits existing mapping and navigation databases inorder to automatically create 3D building models. Ourmethod defines a grammar for representing changes inbuilding geometry that approximately follow theManhattan-world assumption which states...

Interactive Design of Urban Spaces using Geometrical and Behavioral Modeling

14 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

The main contribution of our work is in closing the loop betweenbehavioral and geometrical modeling of cities. Editing of urbandesign variables is performed intuitively and visually using agraphical user interface. Any design variable can be constrained orchanged. The design process uses an...

Visualization of Simulated Urban Spaces: Inferring Parameterized Generation of Streets, Parcels, and Aerial Imagery

14 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

Urban simulation models and their visualization are used to help regional planning agencies evaluate alternativetransportation investments, land use regulations, and environmental protection policies. Typical urban simulations providespatially distributed data about number of inhabitants, land...

Interactive Example-Based Urban Layout Synthesis

13 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

We present an interactive system for synthesizing urban layouts byexample. Our method simultaneously performs both a structure-based synthesis and an image-based synthesis to generate acomplete urban layout with a plausible street network and withaerial-view imagery. Our approach uses the...

Urban Ecosystem Design

07 Jun 2011 | Publications | Contributor(s): Daniel Gerardo Aliaga

We address the open problem of spatial distribution of vegetation in urban environments by introducing a user-guided simulation and procedural system for integrating plants into the interactive design process of 3D urban models. Our approach uses as input 3D geometry of an urban layout from which...
