This is the same problem that i reported earlier under the topic:
'Re: [osg-users] VPB: Call to GDALRasterBand::RasterIO returns wrong
"no data values" for gtopo30'
See previous post for a "hacky" work-around.
BTW, in the similar globe that I created there was some relief on land
as well, and I suspect there is some relief on the land in your model as
well if you just zoom close enough. The problem is that sea level is put
55537 meter above actual sea level, which makes all other relief fade...;)

Hi Robert;
I have try to create the earth database like John's;
osgdem --bluemarble-west -t land_shallow_topo_west.tif --bluemarble-east -t
land_shallow_topo_east.tif --geocentric -o earth/earth.ive --so build.source
osgdem -s build.source -d E020N90.DEM -d /E020N40.DEM -v 1.4 -l 6
And the result is http://img127.imageshack.us/my.php?image=earthto6.png Land
height relief didn't created, only Sea height relief could be seen. I don't
understand why its command created this dirty database. Any thinking about it?
Thanks so much..

Subject: Re: [osg-users] VPB: texture banding at all tile levels
Hi John,
This is a new one for me, never seen banding reported before.
Could you try running a release build of osgdem to see if the problem persists.
Also try out the database on other computers with different hardware
as there is chance that you are seeing a OpenGL driver problem.
Robert.

Hi,
VPB: revision 911
OSG: revision 8323
The following command line is used to create a simple globe (all DEM files
from gtopo30 are used):
./osgdemd -d in/gtopo30/E020N40.DEM [...snip...] -d in/gtopo30/W180S60.DEM
--bluemarble-east -t in/bluemarble/land_shallow_topo_east.tif
--bluemarble-west -t in/bluemarble/land_shallow_topo_west.tif --geocentric
--radius-equator 6378000 --radius-polar 6378000 -v 1.4 -l 6 -o
out/simple_globe.ive -a out/simple_globe.osga
It does not matter what kind of Globe I try to create, I get black bands in
the texture on all tile levels. Please see the screen shots below:

ftp://ftp.weatherone.tv/private/jvl/vpb_texture_banding_2.png
ftp://ftp.weatherone.tv/private/jvl/vpb_texture_banding_3.png
ftp://ftp.weatherone.tv/private/jvl/vpb_texture_banding_4.png
I successfully generated the globe with an earlier OSG revision on a
different computer. However, my memory fails me an I cannot recall the
revision number. Is anyone else experiencing this problem?
Best regards,
John
