MPAS_GRID_DISPLAY_OPENGL, C++ programs which read information from an MPAS Grid file, stored in NETCDF format, and display the main (mainly hexagonal) mesh or the dual triangulation, using OpenGL.

MPAS_GRID_DISPLAY_OPENGL is available in a C++ version.
FERN_OPENGL, a C++ program which uses OpenGL to display the Barnsley fractal fern.
MPAS_DRAW, a C++ program which reads an MPAS NETCDF file and allows the interactive user to select grid and solution information to be displayed using OpenGL.
MPAS_GRID_DISPLAY, MATLAB programs which can read an MPAS NETCDF grid file and display the primary polygonal mesh or the dual triangular mesh.
NETCDF, a data directory which contains examples of NETCDF files, a format for the interchange of scientific data.
NETCDF_MPAS, a data directory which contains examples of MPAS grid data stored as NETCDF files.
NETCDF_MPAS, a C++ library which reads MPAS grid data stored as NETCDF files.
GRID_CELLS retrieves the information defining the polygonal grid cells, and displays them.
TRIANGULATION_FACES retrieves the 3 cell centers around each vertex, and draws the corresponding faces of the triangulation. The display is a triangulated sphere surface.
TRIANGULATION_LINES retrieves the pairs of cell centers that are neighbors, and draws lines to connect them. This actually creates the lines of the triangulation. The display is a triangulated sphere, but there are no areas filled in on the surface, so you can see through to the other side.
