Origami consists of folding paper to build a shape, such as the legendary Japanese crane.
Now you can take this art directly to the computer with Pepakura Desginer, which is an application that enables you to create schemes with 3D shape models that you have created with other programs and then print them and build them.
You just have to leave Pepakura Desginer to trace the folds of any figure you would like to create in paper in three dimensions. When you have your scheme traced, print it and build it with your own hands.
