Which part is realXtend model and which part is photo?

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

Oulu3D: Recent progress

• Creation of best practice recommendations for modelers

• Design of Oulu3D licensing model

• Design of Oulu3D O&M model• Oulu3D Ltd. selected as administrative operator by 3DIA

• Utilization of Oulu3D model in various R&D activities

Oulu3D: Best practice recommendations for modelers

• Prepared in collaboration with the CIE researchers• Based on the lessons learned in the modeling of phase

#1 model and in the subsequent optimization of the model

• Peer reviewed by modeler community in Jan-Feb 2013• When accepted, sets technical requirements for all

future Oulu3D modeling activities
