TRIANGULATION_ORDER1_DISPLAY is available in a MATLAB version.
BEZIER_SURFACE_DISPLAY, a MATLAB program which reads two files defining a Bezier surface and displays it within MATLAB.
MESH_DISPLAY, a MATLAB program which reads data defining a polygonal mesh and displays it, with optional numbering.
OBJ_DISPLAY, a MATLAB program which reads an OBJ file defining a 3D object and displays it within MATLAB.
PLY_DISPLAY, a MATLAB program which displays an image of a 3D graphics file in PLY format;
POLYGONAL_SURFACE_DISPLAY, a MATLAB program which reads two files defining a polygonal surface and displays it within MATLAB.
PWC_PLOT, a MATLAB library which converts the definition of a piecewise constant function into plottable data.
QUAD_MESH_ORDER1_DISPLAY, a MATLAB program which plots piecewise constant data associated with a mesh of quadrilaterals;
QUAD_SURFACE_DISPLAY, a MATLAB program which reads files defining a 3D quadrilateral mesh surface and displays it within MATLAB.
STLA_DISPLAY, a MATLAB program which reads an ASCII STL file defining a 3D object and displays it within MATLAB.
TET_MESH_DISPLAY, a MATLAB program which reads files defining a tet mesh and displays an image within MATLAB.
TRI_SURFACE_DISPLAY, a MATLAB program which reads data defining a triangular mesh of a 3D surface and displays it.
TRIANGULATION, a MATLAB library of routines for carrying out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
TRIANGULATION_DISPLAY_OPENGL is a C++ program which reads files defining a triangulation and displays an image using Open GL.
TRIANGULATION_NODE_TO_ELEMENT, a MATLAB 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_CONTOUR, a MATLAB library which makes a contour plot of a scalar quantity that is defined on a finite element mesh of three-node triangles.
TRIANGULATION_ORDER6_CONTOUR, a MATLAB library which makes a contour plot of a scalar quantity that is defined on a finite element mesh of six-node triangles.
TRIANGULATION_ORIENT, a MATLAB program that reads data defining a triangulation, makes sure that every triangle has positive orientation, and if not, writes a corrected triangle file.
TRIANGULATION_PLOT, a MATLAB library which plots the nodes and triangles that make up a finite element mesh.
TRIANGULATION_QUAD, a MATLAB program which estimates the integral of a function over a triangulated region.
TRIANGULATION_REFINE, a MATLAB program which reads data defining a triangulation, replaces each triangle by four congruent smaller ones, and writes the new triangulation information to a file.
