triangle_display, a MATLAB code which plots a triangulation using files associated with Jonathan Shewchuk's triangle() program.
TRIANGLE_DISPLAY reads the node and element files created by the TRIANGLE program, and displays the information. The user controls how "visible" the nodes and elements are; in particular, nodes can be suppressed, or displayed, or displayed and numbered, and the same is true for elements.
TRIANGLE_DISPLAY is essentially a version of TRIANGULATION_DISPLAY modified to read input files that use the TRIANGLE format.
Jonathan Shewchuk provides a program called showme(), which is able to show the same information, and to perform other interesting operations. However, there are at least three reasons why the TRIANGLE_DISPLAY program is useful:
triangle_display ( 'prefix', node_vis, element_vis )where 'prefix' is the common prefix for the node and element files.

triangle_display is available in a MATLAB version.
fem_basis_t3_display, a MATLAB code which displays a basis function associated with a linear triangle ("t3") mesh.
fem_basis_t6_display, a MATLAB code which reads a quadratic triangle mesh and displays any associated basis function.
gridlines, a MATLAB code which gives the user more control over drawing gridlines on a graph than the builtin "grid on" command.
mesh_display, a MATLAB code which reads data defining a polygonal mesh and displays it, with optional numbering.
tri_surface_display, a MATLAB code which reads data defining a triangular mesh of a 3d surface and displays it.
triangle_files, a data directory of examples of files used by the triangle and showme programs.
triangle_io, a MATLAB code which can read or write some of the files created by jonathan shewchuk's triangle() program.
triangulation_display, a MATLAB code which reads files defining a triangulation and displays an image.
triangulation_plot, a MATLAB code which plots a triangulation as a postscript file.
