Hi Sonya, you have to go through the buttons (forward, backward) in the presentation to see the screenshots. Nevermind. WIth paging I was meaning paging from disk when you have for example huge data that can not fit in the memory all in once, so for this kind of maps I wrote a loader that pages only the visible parts of the maps, with the native osg::PagedLOD.
For you I would suggest to try the 2D ortho settings in the projection matrix for your camera, and probably do some mods in one of the available camera manipulator. Underneath you will still be working in 3D but the display and the interface will be 2D Nick On Thu, May 8, 2014 at 12:03 PM, Sonya Blade <[email protected]>wrote: > Thank You in advance Nikolov, > > I couldn't find any source on the net showing the screenshots of the > mentioned project, the link you provided shows just 3 second banner of it. > Anyway, its good to hear that there are users who have used osg in their > projects with success. > > >My app was even using paging in 2D.
