Please read the Quick Start Guide, or grep the source for intersection.

 is it possible to use the VertexArray from the loaded scenefile in a new
 created Drawable (which will display my analyzing results), AND add
 additional vertices, based on the analyzing process to it?
 Or will i have to allocate a new VertexArray for my Drawable and copy the
 loaded file's VertexArray by Value into it?


Yes, ref counting means you can share objects such as osg::Vec3Arrays.  Note
that OSG itself has a .shp plugin that loads the shape files as Vec3dArray
which while very slow for rendering are very good to accuracy.
