Hardware-Accelerated real-time rendering for 3D Sumi-e painting

This paper presents a method for real-time 3D Sumi-e rendering using 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 hardware. 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.
