Thanks Brad, osga is really what I was looking for. It can store everything and it contains index, so the only overhead on open is to read the index (and not the whole file as with some other formats). I am going to try it. John On Thursday 08 of December 2011 20:20:16 Christiansen, Brad

Hi Torben and Xenon, I was studying OSG sources... (as usual way to study OSG) BTW: What are your performance requirements? Main requirement: I need to load base level geometry and base resolution textures ASAP, f.ex 1s. I will probably inline base-level texture data into the base-level

Hi, what is the best file format for paged scene database? The database may be both - small and big (gigabytes) and it may or may not contain geospatial data. The special requirement is that it should be possible to store non-standard data like reflective color (not present in OpenGL), for

Hi, you can also check out osgEarth. I like the fact that it can convert data (imagery and terrain) into a tms compatible format (jpg, png, tiff). How you display the data is up to you, you can add shaders to do fancy things per layer if you want. regards jp On 06/12/2011 17:44, Chris

Thanks Chris and J.P., I am wondering that flt and vpb and similar formats does not support paging (PagedLOD). In that case, osgb seems to be the best format. Can it store texture data internally, or all jpegs and pngs have to stay as separate files (possibly increasing data fragmentation)?

Hi, you can Control whether it should store the textures internally or externally. the default is internally. BTW: What are your performance requirements? Cheers, Torben -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=44263#44263
