Please err on the side of caution when dealing with unknown code.
GRASS is too big, too complex, too much history to start removing stuff
just because the current crop of developers aren't familiar with it.
grep, cvs, and mailing list searches must be done:
grepping for g3dcell doesn't find much, just lib/gis/opencell.c
That is in the GRASS 5 cvs since the beginning of the cvs (1999).
grass63$ grep -rI g3d * | wc -l
see lib/g3d/ lib/g3d/snap.gif
The r3.* modules #include <grass/G3d.h> and depend on libgrass_g3d.so
3D rasters are now stored in $MAPSET/grid3/$MAPNAME/cell, so probably
g3dcell is an old place for that and is now unused.
Maybe Helena knows...?
