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.
