DEVELOPMENT OF A BROWSER FOR TRAFFIC LINE AND TERRAIN LANDSCAPE

Landscape after construction of traffic line plays an important role in evaluating the visual effect of designed traffic line and the suitability of plan and vertical designs. This paper presents a method to create the overall three-dimension model combined by both the virtual traffic line model and around photo-realistic terrain model. In the overall three-dimension model, the traffic line model is created with data of plan, profile and cross section design, whereas model of terrain outside traffic line is built with digital terrain model and orthophoto. Therefore, the overall three-dimension model can show realistic landscape after construction of traffic line to the most extent. A browser in 3D environment for traffic line and terrain landscape has been implemented based on the method combining the virtual reality and visual reality described above. * Corresponding author.
