The general technique of ink-and-wash drawing consists of brush, ink and paper modeling and brush movement, ink diffusion and paper material simulation. In this paper, we suggest the simplified Qing's tank model that can decrease the computational time of ink diffusion and absorption on korean paper. The suggested drawing system is classified the characteristics of ink-and-wash into ink-shade, diffusion, line and paper. Also, the user's movement using motion sensor and IR sensor in wiimote is transmitted to brush position and direction.

This paper presents a method for real-time 3D Sumi-e rendering us ing normal graphics hardware. Sumi-e is one of the traditional oriental painting styles. Most research on Sumi-e paintings has focused on 2D or :2.5D Sumi-e brushwork simulation. On these systems. complicated user's hand drawing is required to generate the image of Sumi-e effects. and it can render the 2D or 2.5D Sumi-e images only. We present an automated rendering system for 3D image of Sumi-e painting. It uses 3D common object as an input data and does not need any additional input of user brushwork. Especially for the real-time rendering. hardware-accelerated algorithm for Sumi-e rendering is newly suggested in our system. It is designed with efficiency for customer level graphics hard ware. The results of this paper show that the features of traditional Sumi-e painting are successfully modeled and that 3D Sumi-e painting is rendered in real-time effectively.
