Abstract: This paper describes a realistic interactive method for modeling leaves by
deformation based on Laplacian coordinates. This method generates the leaf meshes Using the
silhouette and axial venation data of a leaf as input. The leaf surface can be edited interactively by
using Laplacian coordinates as deformation calculation. The silhouette and axial venation data can
be obtained using laser scanner or calculated by vein patterns. Experimental results show that the
proposed method is very fast in deformation calculation and enough for real-time interactive
application, with good universality. The generated 3D leaves model can not only maintain its area,
but also show realistic effects.

Key words: interactive design, leaves modeling, realistic modeling, Laplacian coordinates
