Thanks,

I am an OpenGL man myself. I know that WW used to be OpenGL running under OpenSceneGraph but they have apparently changed to C# with directX. God knows why - some external pressure I presume or that the programmer was only familiar with that API. They give some real tenuous reasons for it in their FAQ. Still, its up to them.

Interesting info on Celestia LODs. My ViewingDale is geared up for more arbitrary images instead of planets per se, so there are no fixed levels. It doesn't map onto a sphere like celestia and also its orthographic so no height field like WW or google earth.

If we get this map on WW then maybe afterwards ill come back and see what we can do with Celestia too and maybe host on the mother lode too. Its a free map after all.
