Just one additional note, for people wanting to use 'persp' and 
'surface3d' for plotting maps: The 'col' argument differs between 
'persp' and 'surface3d'. For 'persp', it specifies the colour of the 
facets, so it should have (nrow-1)*(ncol-1) values. For 'surface3d' it 
specifies the colours of the vertices, so it should have nrow*ncol 
values.
