NURBS available in BOSL2
I've added NURBS to BOSL2 for those interested in this sort of thing. I'm
not really sure about what amazing possibilities this opens up, but
something, I guess?
@Adrian Mariano avm4@cornell.edu
, nice! I guess it depends on how deep you want to get into NURBS. It can
be used as a basis for just about all curves and surfaces (including
circles, and helices). Not sure what it will add to OpenSCAD, but I will
definitely have to check it out.

Dear all,
I just downloaded nurbes.scad an added it to my "bosl-dir"... neverthess
I receive alot of error messages. Is there a place where I always can
find the complete set of BOSL2 library? (e.g. as zip-file??)
Many thanks

You can always download a ZIP from Github repository:

You can also use Git sub module. This works very well and has lots of nice features but requires the use of Git. I can show you how to do this if that is of interest.

what's best practice to use NURBS patches in your design ?
To get a water-tight model, you need to exactly attach to the points of the
patch.
A Loft between a circle and the patch is viable ?

We've had NURBS, I think in a 2 degree version, in linuxcnc for quite
some time. Decades even. Does barrel profiles on a linuxcnc driven lathe
and such. The lathe makes it 3d, Ditto a 4 axis or more mill. From the
docs it can do full circles but doesn't have to. Whether this definition
matches yours might be open to interpretation. Check out "G5" in the
LinuxCNC docs.

suuuper!
This seems to be a very useful function for 3D-modeling..
include <bosl2/std.scad>;
include <bosl2/nurbs.scad>;
pts = [[13,43],[30,52],[49,22],[24,3],[40,-30]];
debug_nurbs(pts,2);
!!!!rotate_extrude(angle=360, convexity=2);
npts = nurbs_curve(pts, 2, splinesteps=3);
color("red")move_copies(npts) circle(r=1);
Can I do anything to move the created curve -via rotating- into a volume?
yours Karl

I pulled BOSL2 over with git, and now I can update it any time with "git
pull".
From my OpenSCAD library directory, "git clone
https://github.com/BelfrySCAD/BOSL2" and then at any time, from inside
that directory, "git pull" to update.
I think you maybe want something like
rotate_extrude(....) polygon(npts);
or maybe
rotate_sweep(npts, angle=360, ...);
But note that the resulting geometry is self-intersecting, hence invalid,
because the line that closes the polygon of your nurbs curve crosses the
curve.
