HI Zeki, I've just seen that you've made three similar posts with no answers to any of them yet. It's generally best to be patient and stick to one thread per topic rather than splurt it out ever where. If it's a new topic it's also best to start a new thread.
As for the problems you have right now it's hard to know where to start as it's hard to know what you actually understand about scene graphs, OSG particularly, and what you've done so far. The best we can do at this stage is provide general answers. First up, what it sounds like you are trying to achieve is done by OSG users all the time, terrain visualization it's very much one of the OSG core areas of usage. The OSG is capable it's just a matter of learning how to use it. Rather than diving in at the deep end and trying to develop your application right away it may be best to start learning about the various bits of software from a more ground up approach. Getting one of the OSG books would probably be a good starting place. For you particular needs I think you'll need to deal with what coordinate system you want to work in, this will mean converting your path data into the scene graphs coordinate system, or creating the scene graph in the path data's coordinate system, or converting back and forth. The later might be best if you are dealing with whole earth databases as the scene graph will be in Earth Center Earth Fixed. Robert.
