Hi Art,
I have considered implemented Texture LOD controls in the OSG before,
but haven't actually had a direct need for them, so following the
extreme programming principle of only implemented what you need I have
left this one till there was a concrete need... looks like the time
has come :-)
Hi,
I'm the author of the osgvolume example. Its just a quick

Hi Bart,
You can get the frame number form the osg::FrameStamp, you'll find
this attached to the NodeVisitor that is traversing and calling the
callbacks etc. Or just get it from the viewer.

The --terrain functionality is very early days though (checked in
