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

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.

[osg-users] VertexArray from a loaded .osg file.
Hi, i'm using osggis to convert an esri shape file to an .osg file. i want to use the scenedata, more precisely the vertex positions from that file. i need them for an analyzing function, and won't add that loaded file directly into my scenegraph, because i don't want to display it before analyzing is done. 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?
