Trying to simulate a rubber hose, I started wondering, can a curve be twisted?
In the image below bending is illustrated and the rotated frame is meant to illustrate the “twisting” of the curve.
The idea is to simulate a rubber hose connected between two independent moving parts. Initially I did that with segments of polylines which where forced to equal vector angles between segments, and so the segments would behave more or less like the illustrated nurbs curve.
But if I would like to, not only bend the hose, but also “twist” the hose (the curve or the polyline segments) like you would twist a rubber hose making it coil, how would I go about simulating something like that? (using either a nurbs curve or polyline segments). Has anyone tried simulating something such with GH?
The hose (center curve) must start and end aligned with the frame Normals (perpendicular to the planes) since this defines the orientation and rotation of the end-couplings of the rubber hose.
