2D Origami Teapot With Diagram |On the right is a 2D origami
teapot folded from one piece of square paper. The model can be
folded by anyone interested in origami, yet it keeps the
proportions of the Utah teapot unchanged.| On the left is a
teapot with a teacup, also folded from one piece of square paper
(both pot and cup). The configuration of the origami model in
the diagram was modeled by simulating rigid origami, which is
origami represented as rigid polygons linked to each other with
hinges on crease lines. Foward kinematics of the multi-vertex
origami was calculated by combining single-vertex constraint
equations by Belcastro and Hull.1 The University of Tokyo
