Hi Glenn,
That's right J-S. osgEarth never actually writes any terrain geometry to
disk. Rather, it generates terrain tiles at run time as you navigate the
scene. The only relationship to VPB is that they both use osgTerrain.
OK, that's much clearer.
Very interesting. If terrain is never written to disk though, won't
there be lots of effort re-done over and over, say in multiple runs of
the software where the user goes over the same areas? You could probably
cache generated terrain to disk since I guess the Earth changes only
seldom :-)
I guess you generate low LODs first so that the user gets to see
something at least, and then refine as time goes by... What kind of time
can you expect to get good detail, and can you move about freely while
the updates are progressing?
This sounds a bit like my Masters project, where you could move around a
scene and move/deform objects, and the high-quality lighting would
update progressively without ever stopping interaction.
Good work, I look forward to trying it out.
J-S
