Jason, Luigi,
The same problem occurs with the latest Nightly Tarballs
( 2006-12-05 ), cleanly built on Linux FC4.
Ciao,
Paul

I' ll chechout as soon as possible and I' ll let you know the result.
Is there a parameter to set in order to disable the shifting or is
it infering from the dataset?

Hi Luigi and Paul,
Just to clarify, are you guys using the latest CVS or a previous
version. As Robert and Gert mentioned, that line is changed in
the CVS
to fix the problem that Gert found. If you're not using the latest,
could you do a CVS update and see if you have the same problems?
Thanks,
Jason

Hi Luigi and Paul,

Using your data, I have the same problems (shift in image wehen lod

This problem seems related to the line
double xoffset = d_bb.xMin() < s_bb.xMin() ? -360.0 : 0.0;
in osgTerrain/DataSet.cpp, line 520
With this deta, this value is getting set (incorretly? ) to -360.0
If you reset it to 0.0, the problem seems to go away
Hope it helps in diagnosis
The above line is part of fix to handle geocentric datasets that
cross
over the dateline that I applied a couple of months back. Since then
Jason has done a fix to it so that it isn't applied inappropriately -
as some dataset you don't want to have the offset added. Perhaps
Jason's fix isn't general enough.
I'm currently focused on completely some other work so can't dedicate
myself to looking into this right now so if others can jump in an
spot
a fix then please do.
Robert.
