I must make a very smooth, cosmetically impeccible brass tube that tapers

It must be bent in three non-planar curves, none exceeding 45 degrees of
bend.

Anybody got any favorite methods?

Thanks,

If it were me, I'd try to make a straight tube with no taper. And the above
is what I'd end up with. :-/
