TIN

A TIN (Triangulated Irregular Network) is a 3D surface made up of triangular faces. All triangles face the same direction (either up or down).

Each vertex of each triangular face has a height; thus a Contour or a Flow can be used to annotate the TIN.


Properties

  • Area: _area#
    The area covered by the item in square metres.

  • Blended Colours: _bBlend&
    Should the colours of a Surface item be blended between nodes?

  • Clockwise: _bClockwise&
    Is the item geometry defined in a clockwise direction?

  • Delaunay: _bDelaunay&
    Do all edges pass Delaunay conditions?

  • Number of edges: _nEdge&
    The number of visible edges in a Surface.

  • Number of nodes: ex

  • Smooth: _bSmooth& (True/False)
    Set to True to draw with smooth interpolation across each triangle between the colours at each triangle vertex in both the Map and 3D Windows.

  • Splinter factor: _splinter#
    The splinter factor of the Polygon. A circle has a splinter factor of 1. A very long and thin area could have a splinter factor of 100. Polygon items with large splinter factors are often produced by overlapping lines which are almost by not quite the same.
