Hi all,

if I may add my 2 cents:

btw3: Though its doubtlessly more correct to complain about impossibility to
normalize vector of length zero instead of returning <0,0,0> like old
versions did, this behaviour should perhaps be mentioned in "changes that
may break old scenes". TORSPLINE is probably not the only macro out there
that relies on "vnormalize( <0,0,0> ) = <0,0,0>" - my polyhedron-WIP did so,
too :-(

btw4: how about shay's cheap_sweep.inc, published a while ago in the
appropriate newsgroup ? that could be a replacement for many applications of
torspline, though it doesn't give the same geometry - BUT it might as well
suffer from changed behaviour. Didn't test that yet, but there's lots of
vnormalize-calls in it ...
