There are two traditional methods for making polyhedra out of paper: polyhedral nets and modular origami.In the net method, the faces of the polyhedron are placed to form an irregular shape on a flat sheet of paper, with some of these faces connected to each other within this shape; it is cut out and folded into the shape of the polyhedron, and the remaining pairs of faces are attached together.
2-fold 3-fold 5-fold The 5-fold projection is the main drawing on the right page. Max Brückner: Vielecke und Vielflache (1900) Colored as compound of five octahedra, with 3 great circles for each octahedron. The area in the black circles below corresponds to the frontal hemisphere of the spherical polyhedron.
The fold-and-cut problem asks what shapes can be obtained by folding a piece of paper flat, and making a single straight complete cut. The solution, known as the fold-and-cut theorem, states that any shape with straight sides can be obtained. A practical problem is how to fold a map so that it may be manipulated with minimal effort or movements.
In geometry, a space-filling polyhedron is a polyhedron that can be used to fill all of three-dimensional space via translations, rotations and/or reflections, where filling means that; taken together, all the instances of the polyhedron constitute a partition of three-space.
Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
There are several types of 3D woven fabrics that are commercially available; they can be classified according to their weaving technique. [7]3D woven interlock fabrics, are 3D woven fabrics produced on a traditional 2D weaving loom, using proper weave design and techniques, it could either have the weaver/z-yarn going through all the thickness of the fabric or from layer to layer.
