3D Scene
  • Load from extension toolbar or start menu
  • Uses .sxd file format

7
3D Scene
  • 3D Scene with layer added

8
Triangulated Irregular Network
  • Triangulated Irregular Network (TIN) Structure
  • Defined by two elements a set of input points
    with x,y, and z values, and a series of edges
    connecting these points to form triangles.
  • Each input point becomes the node of a triangle
    in the TIN structure, and the output is a
    continuous faceted surface of triangles.
