Hi Ryan,
You make no mention of what type of file you are trying to load. Only
a small number of the OSG plugins support reading form heightfield,
only two of which read height fields directly - these are the gdal and
ive plugins.

i have a doubt: is it possilble to display a bounding sphere in

Thanks in advance

Hi,
It sound normal for me to have a y rotation for result.

Hi,
Bounding sphere is not a drawable, but an osg::Sphere exist, so with you BS
radius and center, you can create a new Sphere to visualize your BS.
Careful to the transformation matrices when getting the center and radius.
