Now that we're using a mesh rather than a real sphere_sweep there's no
reason why we should limit ourselves to having a circular cross section.

In this macro I use an additional spline to describe the shape of the cross
section.

This is beautiful!  Thanks for posting it.

Is it simple to change this a bit to make the cross-section of the swept
object constant when taking a slice through the object parallel to a
specific plane (e.g. x,z)?  Currently the cross-section is constant when
taking a slice through the plane normal to the USpline (path of sweep).

The result would be a bit more caligraphic...the sweep would be 'thinner'
when going certain directions than others.

Thanks,
Leo

I think that what you're describing is the default behaviour of an
isosurface spline, like all the ones on this page and the page before it

<http://www.econym.demon.co.uk/isotut/splines.htm>

The effect isn't very pronounced in these images, but you can probably
make it out in the right of the Bent Prism image.
