4 % Plots cubed-sphere data in mercator projection. (x,y) are
5 % coordinates, c is cell-centered scalar to be plotted.
6 % All arrays (x,y,c) should have dimensions of NxNx6 or 6NxN.
7 %
8 % The default plotting mode is shading faceted. Using this or
9 % shading flat, (x,y) should be the coordinates of grid-corners
10 % and can legitimately have dimension (N+1)x(N+1)x6.

12 % If using shading interp, then (x,y) must be the coordinates of
13 % the cell centers.
