3D output to pdf for animation?

Hello List,

I know I may be hoping for too much, but is there a way to get the 3D figures into a file that may be converted to an animated pdf?

Pdf now allows for inclusion of a 3D figure, and as far as I can see it needs to be in U3D or PRC format.

Has anybody been successful converting any of the matplotlib output file types to U3D or PRC?

Eventually I would like to add the figure in a Latex document and use movie15 to get a rotatable 3D images in my document.
