[GRASSLIST:9622] still have problem with volume visualization

GRASS GRASS user

Hello List Members,

please somebody help me visualizing volmues.
I created a rast3D type volume map, and I would like to see it in nviz.
But adding to nviz a volume has no effect at all. I see nothing.
Is there a tutorial about this topic?

Thanks,
Istvan

Istvan,

I have added a draft new volume manual page to the
NVIZ help menu in CVS [1]. It should also arrive on
the Web server by tomorrow.

Meanwhile you may try the Slovakia3D data set
with these instructions:

-> Slovakia precipitation data (Chapter 7)
    slovakia3d.tar.gz

Hello,
thank you for the help. I downloaded the slovakian dataset, and I
managed to visualize volumes in nviz.
But with my datas I still have problem.
Maybe if someone would try to load it into Grass and see what is wrong
with it, it would be a great help for me.

Thank you,
