These screenshots were taken from the slideshow3D (an OSG based presentation tool), which loaded a PagedLOD database generated by the OSG's osgbluemarble example program. The source data was Nasa's true colour, whole earth imagery (21600x21600 land_shallow_topo_east.tif and land_shallow_topo_west.tif images). The viewer pages in tiles on demand, whilest maintaining a solid frame rate (90Hz on an Linux based AlthonXP1700 + GeforceFX 5600).
