[GRASS-user] 3D raster color coding

[Francois Chartier]

Hi,

I have created a 3D raster from soil properties with about 70K points, with
a* lot of help from the mailing list i must say*.
from the copy of the metadata of the 3d raster (below) it would confirm
that the 3D raster worked and the grid is populated with data.
I have copied below the r3.colors and assigned  'aspectcolr' as a trial.
Unfortunately in the Display window nothing shows up, whether in 2D or in
3D view.  I do not know what i am doing incorrectly.

Once I am done and able to develop the 3D raster of the soil properties, I
will prepare a simple step by step for developing such a raster which may
be useful for others.
