< Hello Grass Users,

Dear John:
Get from the "moon" server the "g.gnuplot.3d" program. This program of Janne
Soimasuo creates 3-d images of vector maps for display with the "g.gnuplot"
program. But the intermediate files created by "g.gnuplot.3d" are in ASCII
format, with the X Y coordinates of the original vector map and the Z value
from the choised elevation raster map.
Bye,
Evaristo
