Constitution & Dynamic Display for Series LOD Model of TIN Terrain by Deleting Vertices

    Graphical Abstract
    • Abstract
  • A new method is presented for constitution of series LOD model of TIN terrain and dynamic display.The method is divided into two steps.One is to setup the series LOD model of TIN terrain by deleting vertices.On the basis of modification of data-structure,we record all information of points and triangles along the simplification of TIN.The other is to dynamic display based on the distance between viewpoint and viewer.
