I collect a series of curves (from clinical images, they are parallel in z direction) and want to loft them. However, because of the image processing, some curves are twisted according to a rotation point in x-y plan (fig1). Thus the lofted surface has the “gaps” (fig2). What I can do now is to manually twist the curves back to minimize the gaps by my eyes (fig3). It’s a time consuming work.
My question is, is it possible to realize the “twisting back” automatically? In my mind it is a quite difficult work, and any suggestion or idea are welcome and appreciated.
The rhino file including the curves and the rotation point is attached.
