Real-Time 3D Sumi-e Painting (sketches_0118)

Introduction This sketch presents a method for real-time 3D Sumi-e rendering. Sumi-e is the one of representative art forms of the Black ink painting in Korea, Japan and China. Most of researches about Sumi-e paintings in NPR (Non-Photorealistic Rendering) have focused on 2D or 2.5D Sumi-e brushwork simulation. We suggest a new automated rendering system for 3D image of Sumi-e painting. The followings are three main contributions. First, 3D Sumi-e rendering needs new concept of Sumi-e painting. We newly model 5 features of Sumi-e painting for 3D and suggest rendering algorithms for each ones: Nong-dam, Brush Stroke, Bal-Muk, Atmospheric Depth & Inside Omission and Paper Effect. Second, only an experienced user could generate Sumi-e image on previous the 2D drawing system. We present an immediate Sumie drawing system using an arbitrary 3D model as an input data. Third, fast real-time rendering should be guaranteed on a 3D game and a VR system. We achieve real-time rendering using hardware-accelerated rendering algorithms, which is an effective method on the graphics hardware of the customer level. Our system consists of Pentium IV 1.7GHz, 640M RAM, nVIDIA GeForce4 Ti 4400 video card. The 3D model has 14,000 faces can be rendered from 12 to 140 frames per second with various painting styles.
