Origami modeling method of leaves of plants and CG image generation of flower arrangement

When certain types of digitate leaves are folded up along their main veins as in leaf buds, their margins of leaves are found to form a simple curve or a few lines. From the viewpoint that the venation and the folding leaf buds would be closely related each other, we will propose a origami modeling method. By use of this method it is shown that complex digitate shapes such as Acer, Cacalia yatabei and Humulus lupulus would be well produced. We will apply this method to get grass stems and twigs of trees and then generate their CG images. We will see that the poetic beauty of wild plants is well produced by our method. To show this fact we will generate CG images of flower arrangement with plants obtained by our method
