    Abstract
  • The technology of real-time dynamic display is the key technology to realize road 3D visual design. This paper applied the creating algorithm of Delaunay triangulation to constructing digital terrain model and accomplished 3D modeling of road entities according to the ideal of divide and conquer. An effective view-dependent simplification algorithm for road 3D model was worked out. Benefit from the algorithm being combined with the technology of showing realistic image, the real-time dynamic browsing platform of road 3D scene was explored. The 3D browser was integrated with the system of road CAD, which realized the visualizations of both design course and design fruits.
