triangulated irregular network
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 TINstructure, and the output is a continuous faceted surface of triangles.
