Documentation A cylinder is a gridded surface given as a family of circles whose positions vary along a set of parallel lines, keeping the cross sectional horizontal curves of a constant shape. NOTE! Given the same working assumptions as in the previous note, a Cylinder can be given by two circles, giving us the control points of the form ((P1, P2, P3),(P4, P5, P6)).
