Hi Fred,
Are you aware of RangeMode PIXEL_SIZE_ON_SCREEN in osg::LOD ?
it's not using the position on screen, but it is efficiently calculating
the diameter of the bounding sphere in pixels on screen, and switches
lod level on that basis.

Hi,
I am trying to implement a view dependent LOD scheme that needs the size and
position of a drawable (or a node) on screen. A 2D bounding box could make the
job. Is there something already done in OSG or should I continue to use
unproject on vertices ?
Regards,
