TRIANGULATION_PLOT\ Plot a Triangulation {#triangulation_plot-plot-a-triangulation align=”center”} ====================
TRIANGULATION_PLOT is a C++ program which plots a triangulation.
TRIANGULATION_PLOT reads one file listing the nodes, and a second file consisting of groups of 3 or 6 nodes that make up triangles, and creates an Encapsulated PostScript image of the triangulation.
triangulation_plot prefix node_vis triangle_vis
where prefix is the common prefix for the node and triangle files, and will also be used to name the output file:
and node_vis is an integer defining the node visibility:
and triangle_vis is an integer defining the triangle visibility:

TRIANGULATION_PLOT is available in a C++ version and a FORTRAN90 version and a MATLAB version.
TRIANGLE, a C program which computes a triangulation of a geometric region.
TRIANGULATION, a C++ library which is useful for working with triangulations.
TRIANGULATION_DISPLAY, a MATLAB program which displays the nodes and elements of a triangulation on the MATLAB graphics screen;
TRIANGULATION_DISPLAY_OPENGL, a C++ program which reads files defining a triangulation and displays an image using Open GL.
TRIANGULATION_NODE_TO_ELEMENT, a C++ program which reads files describing a set of nodes, their triangulation, and the value of one or more quantities at each node, and outputs a file that averages the quantities for each element. This operation in effect creates an “order1” finite element model of the data.
TRIANGULATION_ORDER3, a directory which contains a description and examples of order 3 triangulations.
TRIANGULATION_ORDER6, a directory which contains a description and examples of order 6 triangulations.
TRIANGULATION_SVG, a C++ program which creates an SVG image of a triangulation, which can be displayed by a web browser.
ELBOW3 is an elbow-shaped region, triangulated using order 3 triangles.
ELL3 is an order 3 triangulation of a set of nodes in an L-shaped region.
ELL6 is an order 6 triangulation of a set of nodes in an L-shaped region.
HEX_HOLES3 puts a set of nodes into the double hexagonal hole region using CVT techniques, and creates an order 3 triangulation using TABLE_DELAUNAY.
LAKE3 uses constrained CVT methods to place nodes inside and on the boundary of the problem 14 triangulation region, a lake with an island. An order 3 triangulation is used.
