Based on the virtual geographic information 3D rendering engine VRGIS 3.0 platform, a virtual community DIY planning system is completed by using grid-based model support method. Combined with the CEGUI interface optimization technology and Windows 7 multi-touch display methods, the system is successfully applied to the 2012 Planning Exhibition in Qingdao. The system can meet the general public to participate in community planning requirements, at the same time it can also help professional designer work.
