Hi Rafa. I just found this article in the OSG Forums and am very interested in osgvp.
Is there a tutorial on osgvp? And if so, would you tell me where? I've downloaded the "snapshot" for all platforms and am compiling the projet with maven. I just need a good tutorial as to how to use this product. I really really like the fact that it can possibly load my dted and cib terrain data on the fly w/o having to pre-generate this data specifically for osg. Thanks so much Rafa.
