TRIANGULATION_ORDER4 is a dataset directory which contains examples of triangulation data of order 4.
Defining a triangulation requires two files:

TRIANGULATION_DISPLAY_OPENGL, a C++ program which reads files defining a 2D triangulation and displays an image using OpenGL.
TRIANGULATION_ORDER3, a data directory which contains examples of TRIANGULATION_ORDER3 files, a description of a linear triangulation of a set of 2D points, using a pair of files to list the node coordinates and the 3 nodes that make up each triangle;
TRIANGULATION_ORDER4, a data directory which defines TRIANGULATION_ORDER4 files, a description of a linear triangulation of a set of 2D points, using a pair of files to list the node coordinates and the 4 nodes that make up each triangle;
TRIANGULATION_ORDER6, a data directory which contains examples of TRIANGULATION_ORDER6 files, a description of a quadratic triangulation of a set of 2D points, using a pair of files to list the node coordinates and the 6 nodes that make up each triangle.
TRIANGULATION_PLOT, a FORTRAN90 program which creates an Encapsulated PostScript image of a triangulation.
TRIANGULATION_T3_TO_T4, a FORTRAN90 program which reads information about a 3-node triangulation and creates data defining a corresponding 4-node triangulation (vertices + centroid);
BOX4 is a rectangular region.
There are 44 nodes and 24 elements.
