ORI-REF: A Design Tool for Curved Origami based on ReflectionA lot of designing methods for origami with mathematical approaches have been studied. It was revealed that designing curved origami is a difficult problem. However, it is relatively easy to design a curved origami which has only planar curved folds. The planar curved fold is generated simply by reflecting a part of a curved surface. As shown in below image, a reflection adds a curved fold on a sh
