Easily Create Origami with Curved Folds and Surfaces

Origami―making shapes in basic terms via folding―reveals a desirable sector of geometry woven with quite a few representations. the realm of origami has stepped forward dramatically because the creation of machine courses to accomplish the mandatory computations for origami design.

3D Origami Art offers the layout tools underlying 3D creations derived from computation. It comprises a number of images and layout drawings known as crease styles, that are on hand for obtain at the author’s web site. in the course of the book’s transparent figures and outlines, readers can simply create geometric 3D buildings out of a suite of strains and curves drawn on a second plane.

The writer makes use of numerous shapes of sheets similar to rectangles and standard polygons, rather than sq. paper, to create the origami. a number of the origami creations have a 3D constitution composed of curved surfaces, and a few of them have advanced types. even if, the historical past thought underlying all of the creations is particularly uncomplicated. the writer indicates how diversified origami types are designed from a typical theory.

Example text

With commercially available CG or CAD software, you can make a 3D shape, arrange configuration faces onto a plane, and apply the methods in this book to draw a 3D origami crease pattern. Still, trial and error in design is a tough thing as each step takes time. So, I have written ­several 3D origami design-dedicated software programs myself. For instance, ORI-REVO has been developed for the easy design of the axisymmetric 3D ­origami shapes presented in Chapters 1 and 2. The software screen is structured as shown.

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. After folds, the shape becomes two ­connected solids as in the photo. The ­connected section is the twist-closing structure. 2. The upper and lower shapes do not have to be identical as far as the equally spaced vertical mountain fold lines and the slant v­ alley fold lines for a twist-closing structure run seamlessly across the crease patterns.

7b. 7c, allowing the units to be placed and connected at the vertices of the square tiling pattern. Pleats have orientations. On the neighboring units, the pleat faces oppositely from the other. 3 Connecting Different 3D Origami Shapes Identically shaped units can be connected by the method described earlier. Even differently shaped units can be connected as long as their connectors are the same width. 8 cannot be connected as is because their connectors are different widths. In this case, the connector width of either crease pattern can be made equal to the other by enlarging or reducing the entire crease pattern.
