You mean mipmaps that are stored in the in OpenSG Image? Those are
automatic, whenever you use the Image in a texture. In general, if you
have the texture's filter set to use mipmaps, they are created when the
texture is uploaded.
However, the paper you reference talks about dynamically created
mipmaps. Those are a different story, and I don't have an immediate
solution for that, as it will take a multipass rendering approach. It
would be very interesting to be able to get this as an option for the
TextureGrabForeground (hint, hint :).
