Hello,

Do you mean how the matrix is projected on the (x,y)-plane? In that
case, you can reverse de rows of the matrix as in
mesh (reverse(mat), x0, y0, width, height) $
On the other hand, I'm planning to rename object 'mesh' and call it
'elevation_grid', as in VRML. The idea is to call 'mesh' a new more
general 3d graphic object. Some experimental examples and explanations here:

I can also change how the matrix is projected on the (x,y)-plane in a
more convenient way, perhaps following standards in image analysis.
Also, I'm open to suggestions on the naming of the two functions.
Thanks.
