triangulation_svg, a C++ code which creates a Scalable Vector Graphics (SVG) image of a triangulation, which can be displayed by an web browser.

The code reads one file listing the nodes, and a second file consisting of groups of 3, 4 or 6 nodes that make up elements.


triangulation_svg prefix
where 'prefix' is the common prefix for the node and element files, and will also be used to name the output file:

TRIANGLE_SVG, a C++ code which uses Scalable Vector Graphics (SVG) to plot a triangle and any number of points, to illustrate quadrature rules and sampling techniques.

TRIANGULATION, a C++ code which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.

TRIANGULATION_NODE_TO_ELEMENT, a C++ code 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_PLOT, a C++ code which plots the nodes and elements of a triangulation as a PostScript (PS) file;
