[GRASSLIST:5534] spherical globe projection in nviz

Don't I remember that nviz used to be able to wrap lat-lon rasters onto a
spherical globe.

I think that Bill Brown even made a cover of Grassclippings with such a globe
mapping (perhaps I show my age here :wink: ).

Can it still do that? How?

AFAIK, the OpenGL NVIZ has never done that. Perhaps an Irix version?
While not exactly GRASS, the program Xplanet can do that with a suitable
image input (http://xplanet.sourceforge.net/).

Yes, it will have been the SG3d software which only runs on SGI.
The source code is included in 5.0.x:
src.contrib/GMSL/SG3d/

[BTW: There is also
src.contrib/GMSL/sg4d/
]

Kind regards
