Abstract： In order to solve the problem of recognition ability reduction caused by the excessive number of polygonal networks in the traditional simulation system,a 3 D simulation system for green building was designed. In the hardware design,the panoramic camera is used to obtain the full-angle images of the green building,and with the support of the ZigBee baseboard,the CC2530 chip is used to control the sensor to obtain the building space position and tilt angle information. In the software design,the object-oriented method is adopted to design the green building foundation,and the design of the pile foundation is optimized in consideration of safety and cost. The virtual visual technology is used for texture mapping and seamless connection of the framework after constructing the green building framework. The test results show that the designed 3 D simulation system for green building has complete texture mapping, high consistency of building components during the simulation process,and hith identifiable ability.
