ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention pertains to the field of origami and papercraft. More particularly, the present invention pertains to constructing three-dimensional shapes from paper, or more generally any printable and foldable surface, according to a plan, affixed to the paper, that indicates where on the paper to place images so as to be displayed on the visible surfaces of the constructed figure.
2. Description of Related Art
How to construct from paper a cubical shape, such as a so-called “waterbomb,” is well known. For example, “The Ultimate Papercraft and Origami Book” by Paul Jackson and Angela A'Court, provides a description of how to construct a waterbomb starting with a square piece of paper and constructed by aligning edges and centerlines. The cubical shape that results is proportional in size to the single dimension of the square paper used to construct it. A piece of paper 8.5″ on a side, which is as large a square piece of paper as can be produced from letter-size paper (i.e. paper of dimensions 8.5″×11″), will produce a cube approximately 2.125″ on a side (vs. a cube 2.750″ on a side for an 11″×11″ square piece of paper).
What is not known is how to use essentially all of a piece of non-square paper, and so be able to produce a larger cube from letter-size paper. In addition, what is not shown in the prior art is how to indicate on a piece of non-square paper where to place images so as to end up displayed on a side of a cube constructed from essentially all of the paper.
What is needed more generally is a way of indicating how to construct a three-dimensional figure from a piece of paper (or any foldable printable surface) bearing images that end up on visible surfaces of the constructed figure. In addition, what is needed is a way of indicating how to use paper that is non-standard in shape, for example rectangular but non-square, in the construction of a cube, without simply cutting the paper to form a standard shape of paper (for example, cutting rectangular paper into square paper in case of constructing a cube).
SUMMARY OF THE INVENTION
Accordingly, the present invention provides a construction paper from which to construct, according to the principles of origami and papercraft, a three-dimensional figure having visible surfaces, the construction paper comprising: a piece of paper or more generally any piece of foldable material that can be used as a printing surface (including for example foldable transparency film used by laser printers and copy machines, such as is sometimes made using stress oriented polyethyleneterephthalate available under the trade designation “Mylar” from E.I. duPont deNemours Corp. of Wilmington, Del.); and a construction diagram, the construction diagram comprising an image matrix and fold lines, the image matrix for indicating what areas of the paper will end up on visible surfaces of the three-dimensional figure, and the fold lines for showing how to fold the paper to produce the three-dimensional figure; wherein an area indicated by the image matrix corresponds to either an entire visible surface or to part of a visible surface, and if to part of a visible surface, the area is folded into an orientation so as to unite with other areas of the image matrix and so provide an entire visible surface.
In another aspect of the invention, the paper is non-standard, in that it is different in shape than the paper that would normally be used to construct the intended three-dimensional figure, and some fold lines are truncated, i.e. are truncated based on the difference between the paper used and the standard paper, so as to adapt the non-standard paper to a standard paper corresponding in size to the larger dimension of the non-standard paper.
In a particular embodiment, the three-dimensional shape is substantially a cube. In that embodiment, the standard paper is square, and in truncating fold lines of non-standard (non-square rectangular) paper, some fold lines are truncated and the paper is folded as if it were square in shape having as the length of any side the larger length of the non-standard paper. The result is a cube as large as could be constructed from a square piece of paper with each side having a length equal to the greater of the two lengths of the non-standard (non-square rectangular) paper.
Sometimes it is preferable to trim some of the paper beyond the construction diagram, depending on the dimensions of the paper. Usually, the excess is removed from the two ends of the longer dimension of the paper.
The construction paper of the present invention can be created for the most part on a computer, or on different computers connected by a network. Ultimately, however, when a tangible construction paper is produced, if color pictures are to be affixed to any areas of the image matrix, the construction paper is preferably produced by printing the construction diagram on paper, or any other printable and foldable printable surface, using a color printer.
