I've got [url=]this image of Earth 370 million years ago[/url], [url=]Mollweide projection[/url].

I'm running Wolfram Mathematica 8 in the campus lab. What instructions do I need to type in to convert this to a globe?

I found this algorithm which can project an image onto a sphere, but it doesn't get rid of the black parts:

sphere = SphericalPlot3D[1, {theta, 0, Pi}, {phi, 0, 2 Pi},
Mesh -> None, TextureCoordinateFunction -> ({#5, 1 - #4} &),
PlotStyle -> Directive[Texture[image]], Lighting -> "Neutral",
Axes -> False, Boxed -> False]


I'm thinking I should convert the map to the Mercator projection first. Is there an algorithm for this?
