A Template Based Dynamic Modeling Method of 3D Road

To solve the problem of 3D real-time visual design for roads,a method based on road template was realized based on lateral and lengthwise structures and the geographic environment of the road.Combining real-time interactive data and the template,the method dynamically creates a 3D road model adapted to the terrain and complying with road engineering and technical standards mutually.An application built on the Gaea Explorer,a 3D-GIS platform demonstrates the feasibility of the proposed method.
