MPAS_GRID_DISPLAY_OPENGL\ Display MPAS Grids {#mpas_grid_display_opengl-display-mpas-grids align=”center”} ============================
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.
grid_cells filename.nc
where
displays a plot of the polygonal faces of the primal mesh.
triangulation_faces filename.nc
where
displays a plot of the faces of the dual triangulation.
triangulation_lines filename.nc
where
displays a plot of the lines of the dual triangulation.

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.
You can go up one level to the MATLAB source codes.
