I've just started looking at Helix3D. It looks pretty awesome.

I was just wondering if anyone knew if it was possible or how difficult it would be to add a dynamic texture to something like the Earth demo, so as you zoomed in, you give the zoomed in region higher resolution textures? there are already a map tiling library (brutile) that can handle the fetching of the correct tiles from a mapserver, so it would just be a matter of replacing the texture with the correct resolution one in the correct place right?

Yes, this would be a nice demo! I think you also need some level-of-detail (LOD) algorithm here - if you zoom in and tilt you will expose a large number of tiles! Does anyone know an easy way to solve this?

How would the dynamic texture work though? I don't know much about this kind of thing. I know how it works in a 2d environment, but am out of my depth with 3d at the moment.

MapSUI is a great example of map streaming using brutile, so i guess it would be a similar thing to this. I would be willing to lend a hand with the mapping side of things if someone can help with the 3d side of things!

If we can get this working i can see it looking like google earth, which would be awesome.
