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.

Are you trying to do terrain?

VPB isn't a format. VPB is a tool. It generates data in any OSG-writable
format,
including .osg/.ive/.osgt/.osgb. It does support terrain paging with Pag
Hi,
you can Control whether it should store the textures internally or externally.
the default is internally.
BTW: What are your performance requirements?

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 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.

Well, generally the only paged formats OSG supports (excepting specialized

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 inst
