A Three-Dimensional Visualization On-line Monitoring System for Large Buildings with OSG and ProE

To monitor and show the large buildings' strain, vibration, pressure and other states, a three-dimensional visualization on-line monitoring system based on ProE and the Open Scene Graph (OSG) is proposed in this paper. Firstly, design the buildings' structure using the 3-D modeling tools ProE and then get the digital buildings. Then, with the OSG 3D graphics toolkit, accomplish the zooming, roaming and location functions. Finally, based on the mode of data driven, real-time drawing and rendering the building's all kinds of sensors, and complete the safety condition monitoring for the key positions.
