Bill and Jaro,
(I am sending this to developers list too, in case that
somebody would like to look at it)
which version of GRASS do you have ?
It appears that the nviz bug is in beta8 and
later versions (Justin tried it on SGi
and Bob reports it too), but not in the older versions.
I put a small test DEM at (approx 300x200) http://www2.gis.uiuc.edu:2280/modviz/hooder/hoodtest.ascii
(Bill you can find it in location hood, mapset helena as sel.80)
and 3 images together with the nviz state files
so you can view it exactly as I did. Please check
whether you will see the same problem in your older versions
of nviz.
the images and state files are:
hoodeltest1.gif hoodel1.state this one has the masked-out areas quite visible
hoodeltest2.gif hoodel2.state this one is OK
hoodeltest3.gif hoodel3.state this one has the masked areas only as black points
As for r3.showdspf, the p option which draws walls of the box obviously
does not work - this option reads from the grid3 file rather than
dspf file which is used by isosurface so it appears that the grid3 part
is broken. For GRASS5.0 this can be considered lack of functionality but
it would be useful to solve it for 5.1
Jaro, I think that Markus has resolved the vis5d, grid3 problem.

Hela,
I have never encountered a such problem in my grass5.0beta6. I am
still using early versions of NVIZ adopted for Mesa (nviz2.1, nviz2.2).
I displayed your test data using various positions, zooms, exagg, etc.
without any problem.
We should track down the change in the NVIZ code which caused this bug...
Maybe Markus could send us a complete list of bugfixes and changes made in the NVIZ
for each relevant version of GRASS?

sure.
Find attached the log from 29. Dec. 2000 up to today.
This are the tags:
o GRASS 5 beta 10: tagged as "release_grass5beta10_7_december_2000"
o GRASS 5 beta 9: tagged as "release_grass5beta9_6_december_2000"
o GRASS 5 beta 8: tagged as "release_grass5beta8_26_july_2000"
o GRASS 5 beta 7: tagged as "release_grass5beta7_20_april_2000"
o GRASS 5 beta 6: tagged as "release_grass5beta6_16_feb_2000"
So if beta6 was o.k., the bug can be traced within CVS as CVS was started
in 1999.
