quad_surface_display, a MATLAB code which can display a 3D surface that is defined by a mesh of quadrilaterals.
The input from the user includes:
quad_surface_display ( node_num, node_xy, quad_num, quad_node, value )where

quad_surface_display is available in a MATLAB version.
ball_and_stick_display, a MATLAB code which demonstrates the creation of a 3d "ball and stick" image;
bezier_surface_display, a MATLAB code which reads two files defining a bezier surface and displays it within MATLAB.
mesh_display, a MATLAB code which reads data defining a polygonal mesh and displays it, with optional numbering.
obj_display, a MATLAB code which reads an obj file defining a 3d object and displays it within MATLAB.
polygonal_surface_display, a MATLAB code which reads two files defining a polygonal surface and displays it within MATLAB.
quad_surface, a data directory which contains a description and examples of 3d surfaces defined by a quadrilateral mesh.
tet_mesh_display, an MATLAB code which reads files defining a tet mesh and displays an image within MATLAB.
tri_surface_display, a MATLAB code which reads data defining a triangular mesh of a 3d surface and displays it.
triangulation, a MATLAB code which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
triangulation_mask, a MATLAB code which takes an existing triangulation and deletes triangles and their corresponding nodes as requested by the user.
triangulation_order1_display, a MATLAB code which reads files defining a piecewise constant triangulation of data, and displays a corresponding 3d surface.
triangulation_order3_contour, a MATLAB code which can make a contour plot of a scalar quantity that is defined on a finite element mesh of three-node triangles.
triangulation_order6_contour, a MATLAB code which can make a contour plot of a scalar quantity that is defined on a finite element mesh of six-node triangles.
triangulation_orient, a MATLAB code 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 code which can make plot the nodes and triangles that make up a finite element mesh.
triangulation_refine, a MATLAB code which reads data defining a triangulation, replaces each triangle by four congruent smaller ones, and writes the new triangulation information to a file.
