correspond to a single point on the child curve, and you again make triangular faces, but the opposite way. My offset() code can produce the face list for connecting the parent and child curves where both deletion and insertion of points may occur.

penSCAD exposed the Clipper offset module as a function. It seems very fast and robust. I think it has been requested before and all the 2D geometry modules are fast enough to be functions and I can't see any downsides. Even if somebody has a function with the same name it would just override the built in. > PR#4478 will, among other things, let you render a 2D object into a list of lists of points, which achieves that goal. > > _______________________________________________ > OpenSCAD mailing list > To unsubscribe send an email to discuss-leave@lists.openscad.org
