Hi Shyane,
I've not been at my desk too consistently this last few weeks due to
school holidays, so not able to dig down into all threads.
A couple of general comments. If intersections are slow then consider

Hi Shayne,
If KdTree aren't helping performance then you either have a bottleneck
outside the actual ray to triangle intersection, or perhaps the
KdTree's aren't being assigned

Hi Shayne,
The LOS and HAT techniques use the osgUtil::IntersectionVisitor

Hi Shyane,

school holidays, so not able to dig down into all threads.
A couple of general comments. If intersections are slow then consider
enabling the building KdTree's on your scene graph, this will greatly
improve
Hi Shayne,
Also, if you're intersecting against a PagedLOD database the highest
level of detail of the database is loaded and cached by the
DatabaseReadCallback in the osgSim::HeightAboveTerrain class. So if
your intersections are grouped spatially together they have a better
chance of being
Since I didn't receive any input or feedback on my previous inquiry, I'm
assuming no one has used osgSim very much in an extensive setting.?.?
At any rate, I've done some further investigation. It appears that
performance is very poor when HAT inquiries are randomly called in different
portions
