QUAD_SURFACE_DISPLAY is a MATLAB program 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 program which demonstrates the creation of a 3D "ball and stick" image;
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.
MPAS_GRID_DISPLAY, MATLAB programs which can read an MPAS NETCDF grid file and display the primary polygonal mesh or the dual triangular mesh.
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.
QUAD_SURFACE, a data directory which contains a description and examples of 3D surfaces defined by a quadrilateral mesh.
TET_MESH_DISPLAY, an 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 which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
TRIANGULATION_MASK, a MATLAB program which takes an existing triangulation and deletes triangles and their corresponding nodes as requested by the user.
TRIANGULATION_ORDER1_DISPLAY, a MATLAB program which reads files defining a piecewise constant triangulation of data, and displays a corresponding 3D surface.
TRIANGULATION_ORDER3_CONTOUR, a MATLAB library 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 library 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 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 can make plot the nodes and triangles that make up a finite element mesh.
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.
QUAD_SURFACE_DISPLAY_TEST reads node, quadrilateral and value data from files, and calls QUAD_SURFACE_DISPLAY to plot it. Files you may copy include:
