A few days away from the board and you geniuses have wrought a revolution. (As the World Turns, so to speak.)

My 3D tools are Carrara, Hexagon and SketchUp, all capable of good low poly output. For winding order, which would be the best export format, OBJ, 3DS, or DXF? How about Viewpoint's mts/mtx and the U3D standard?

Add my handclapping to an earlier recommendation for texture mapping. And here is a curve ball for you: normals maps. As you know, with normals maps you can show a lot of pseudo 3D on lowpoly models.

You might talk with Viewpoint about a partnership. They nearly killed off the best web 3D with a lousy business model. Rather belatedly, they now have made Viewpoint models free to distribute, published with a free utility, Enliven. If Enliven could write KML for mts geometry and mtx scripting, that would be a hit for Google Earth. I'm thinking Viewpoint would be eager for any chance to make a comeback.

I realize that Google Earth may not be optimized for "virtual reallity" at model scale, but you have the best access to a potentially HUGE market, which is interactive place-based 3D. Any storefront business is going to want its building and sign on Google Earth!
