Hi Robert,
In CullVisitor when culling it uses the current CullingSet when checking
for small feature culling, that is why i changed both the current
CullingSet and the settings in CullVisitor in my callback, so that the
current node isn't culled by small feature culling as well as the

Hi all,
The class osg::TextureRectangle seems to be using an OpenGL extension,
which is not supported in all OpenGL implementations. Unfortunately, it
seems that osg::TextureRectangle checks for support of these extensions
only when the texture is being applied (in TextureRectangle::apply),

HI Ryan,
This problem will be down to the camera manipulators setting their
default mode position based on the total bounding sphere that encloses
your whole scene including lights.
Setting the home position of the camera manipulators directly would be
one way of tackling this problem.

Leonard,
It's highly unlikely that a Terrapage model would be in an orthographic or
stereographic projection. I'm pretty sure Terrex can only support localized
projections like UTM and state plane.
If you are trying to guess what CS the terrain is in, take a lat/long you
know is on the terrain

OK, the selectorId=6 means that you have a flat, geographic dataset,
i.e., x=long, y=lat. The values may be offset (by the origin values in the
projinfo), but it is probably that simple.

The glx/gl finding issue is one I've seen from even before the cmake

For some odd reason, a source type of GL_UNSIGNED_BYTE rather than _FLOAT
