Importing time-dependent mesh I have recently found that Mathematica (a mathematics software) may export .stl files, which may be used for Blender. This is very good for me because I am interested in mathematics visualization, and this team Mathematica-Blender seems to be most convenient for this purpose. However, I suppose that when working with animations, I will need curves or surfaces which move according to mathematic equations. See for example the figures in the following video:

Film Dimensions, Chapter 4

It is extremely easy to export just one mesh, allowing me to use Blender for mathematics pictures. But for animations, since Blender does not seem to support high mathematics, it would be great to export somehow a time-dependent mesh. Is there something like this available? More concretely, focusing on the Blender problem (and not in Mathematica), is there any file type from which Blender may import a time dependent mesh?

Any idea or suggestion will be welcome.
You can use the NewTek MDD and PC2 formats (though you may have to enable their separate addons in the user preferences to get those import/export formats to appear).

This can be used in conjunction with the 'Mesh Cache' modifier to play back a sequence of external meshes:



There also appears to be a script to import .obj sequences as well, which tends to be a more common format, found here at BlenderArtists, but I am not  sure of any potential limitations it may have.
