I'm using OSG v. 1.2
I'm following
http://www.openscenegraph.org/index.php?page=UserGuides.Osgdem
(exept gdaladdo -r average, which is not working for me).
All is somewhat well (maybe, too slow database
generation), but texture and mesh are misaligned (in fact,
one of them is flipped around Y axis). Data files are OK.
Is there bug in DataSet.cpp?
Steps to reproduce:
1) Download
http://www-static.cc.gatech.edu/data_files/large_models/ps/ps_texture_1k.png
and
http://www-static.cc.gatech.edu/data_files/large_models/ps/ps_height_1k.png
Verify that files are matching.
2)
$ gdal_translate ps_height_1k.png ps_height_1k.tif
$ gdal_translate ps_texture_1k.png ps_texture_1k.tif
3)
$ osgdem -t ps_texture_1k.tif -d ps_height_1k.tif -l 3 -v
0.001 -o puget.ive -a puget.osga
4)
$ osgviewer puget.osga
Playing with t & l keys, it's clearly visible that mapping
does not follows mesh.
