| Abstract: | The terrain structural line is the basis for rendering, representing and applying terrain. Firstly, the basic idea to generate the terrain structural line by triangulated network is introduced in this paper. After that, the key techniques to generate the terrain structural line are described, such as building contour tree, generating terrain structural line, auto-generating ridge of nek, linking terrain structural line and building structure tree. |
