Easily Create Origami with Curved Folds and Surfaces
Origami―making shapes purely via folding―reveals a desirable region of geometry woven with various representations. the realm of origami has stepped forward dramatically because the creation of desktop courses to accomplish the mandatory computations for origami design.
3D Origami Art offers the layout equipment underlying 3D creations derived from computation. It comprises various pictures and layout drawings referred to as crease styles, that are to be had for obtain at the author’s site. in the course of the book’s transparent figures and outlines, readers can simply create geometric 3D constructions out of a collection of strains and curves drawn on a second plane.
The writer makes use of a variety of shapes of sheets similar to rectangles and commonplace polygons, rather than sq. paper, to create the origami. some of the origami creations have a 3D constitution composed of curved surfaces, and a few of them have complex varieties. notwithstanding, the historical past concept underlying all of the creations is particularly easy. the writer indicates how various origami varieties are designed from a standard theory.

Getting a bit away from the concept of “wrapping a solid” gives more freedom for creating a variety of shapes based on the same principle. 18. Its folded shape is an inverted mirror image. When one crease pattern is placed above the other, their vertical mountain fold lines are aligned at the same intervals, and boundary valley fold lines coincide with each other. For this reason, the fold lines are connected seamlessly throughout the two crease patterns and can actually be folded. 2 crease pattern is added with a twist-closing structure at the top and bottom ends.
Set θ to 180°/N, where N is the number of circumferential segments used for making the solid and equals the number of components placed. Therefore, N is 6 in this example. indb 7 7 5/12/16 12:53 PM a b b mountains because the projections should be on the outer surface. 17 Layout of fold lines for making projections on 3D-pleat cylinder type. also place the new point so as to divide the middle horizontal line and the bottom side at the above-mentioned ratio. 16c.
