[osg-users] How to implement pagedLOD without reading from files?

Hi Robert,

I think I have all the coding done and in my opinion  it should work.
But it doesn't and I figured out why.
When using osgDB with my own ReaderWriter it automatically uses the
dynamic load feature and the ReaderWriter is expected to be a dll in the
plugins folder.
Unfortunately my ReaderWriter is very much depending on many classes I
have in my
project and also has dependencies to Qt.
Creating such a dll would be a complete overkill of link dependencies.
Is there any way avoiding the dynamic load mechanism and using an
instance of a
class being part of my static libs?

Thanks in advance for any hints.
