NIMO: UO WP3 objective #3-1: Oulu3D

• Joint initiative to build open interactive 3D virtual model of downtown Oulu atop the realXtend platform• Outdoor modeling of selected blocks• Indoor modeling of selected key buildings• Hosting of the model in public Internet

• Phasing of the model• Phase #1: ”9” (available in 2012)• Phase #2: ”50” (available in 2013 if additional funding is obtained)• Phase #3: ”City” (available in ?)

• Division of activities• Data collection (photographs, blueprints, laser scanning)• realXtend modeling• Hosting of the model• IPR and O&M of the model• Utilization of the model

realXtend - Open source platform for the 3D Internet• http://www.realxtend.org• Client-server architecture• Tundra SDK, Naali viewer• Extensible scene architecture

Which part is realXtend model and which part is photo?

Differences between realXtend model (low polygon) andCAD models (high polygon) have to be understood

NIMO: UO WP3 objective #3-2: Pervasive city game

• Pervasive gaming ~ seamless integration and interaction of real world and game world

• Design and implementation of incremental prototypes of pervasive games for youth utilizing the 3D virtual model

• Evaluation via game play by significant number of real players in authentic urban setting

• Close collaboration with the upcoming MESSI project of City of Oulu’s Centre of Youth Affairs

First pervasive city game ”Street Art Gangs”

• Teams of players try to create virtual graffitis around downtown Oulu, at the same time stopping other teams from creating graffitis

Future work

• UO WP3 objective #3-1: Oulu3D• Operationalize O&M• Add first services • Release model to general public (Dec 2012 ?)• Obtain additional funding to build phase #2 (”50” blocks)

• UP WP3 objective #3-2: Pervasive city game• Finalize implementation of Street Art Gangs ver. 1• Conduct field trial with Street Art Gangs ver. 1

Oulu3D has brought the players together!
