Research on Intelligent Method of Generating Virtual Landscape along High-speed Passenger Dedicated Rail Line

It is an important research topic to do the landscape design and evaluation, especially the pre-assessment, of high-speed passenger dedicated rail line effectively. This paper discusses the feasibility and necessity of using VR (virtual reality) technology to evaluate the high-speed railway landscape design comprehensively. For the rail line and ancillary facilities being the primary target of landscape design for high-speed railway, the building methods of them are studied in the first place. Based on an integrated analysis of the virtual landscape elements along high-speed rail line, a hierarchical structure of the landscape along the line is built, and a model database of ancillary facilities is established. Furthermore, with OpenFlight database, a standard data formats as a tool, the intelligent generation method of 3D rail track model is achieved. Then, using the Instances and External References and operating model data files through OpenFlight API's programming interface, the generation of ancillary facilities environment is accomplished.
