Data Sets
This page is under construction
The following data sets represent the main types of
data sets appropriate to the project.
The data sets are split into four types, according to whether
(1) the data is 3D (free form surfaces) or 2.5D (terraintype surfaces)
and
(2) the data is in the form of (x,y,z) points, in no particular ordering
(an "unorganized point set") or in the form of a triangulation.

The data format for points sets is an integer representing the number
of points, followed by the coordinate triples of the points.
The data format for triangulations is first a pair of integers, n and m,
represnting the number of points and the number of triangles
respectively, followed by the coordinate triples of the points and
then the integer triples of the triangles. As regards the triangle triples,
the points are indexed from 0 to n1. This format is often
referred to as an "indexed face set".
