transforming 2D plots to the surface of a sphere

Hi there Sagers:

I'm trying to use a cartographic projection f:R2S2R3 to map Sage 2D graphics objects onto the sphere S2. Projecting points is easy, but how can i project polygons or function plots? Do i somehow grab the graphics object points and use point3d and f?

Thanks for your attention. Alex
