We present an optimization of the height-field water-column based approach for water simulation, providing three-dimensional animation of water flow on natural terrains. Our approach eliminates the storage and management of redundant virtual pipes between columns of water and also removes output dependency for parallel implementation, making it efficient for interactive computer graphics applications. We show a GPU implementation of the proposed method that runs at interactive frame rates with rich lighting effects on the water surface, including light wavelength dependent attenuation and light scattering.

A technique to synthesize a 3-D Kabuki face model from ancient images is proposed. Kabuki is a traditional Japanese theater art. Kabuki researchers can know some ancient information of Kabuki from the ancient 2-D images such as Ukiyo-e (Japanese drawing) and Kumadori images (Kabuki makeup). Compared with the real face images in photographs and paintings, the face images in Ukiyo-e and Kumadori images were distorted a little from the real face for art representation. Hence, it is necessary to synthesize a new 3-D face model between the 3-D real face original model and the 2-D images. A deformation technique is proposed for transforming 3-D real face original models according to the 2-D images, and a mapping algorithm is given to map the images onto the 3-D face shape model. To ensure balance between precision and smoothing of 3-D model deformations and mappings, the radial basis function (RBF) is developed and a multilevel RBF is proposed. This multilevel RBF solver can be used to deform the 3-D real face model as well as map the 2-D images onto the 3-D face model. Some experimental results are given to demonstrate the effect of this technique.
