Storoke-based Suibokuga-Like Rendering for Three-Dimensional Geometric Models

Abstract

Non-photorealistic rendering has become an important research topics in computer graphics in recent years. We have previously proposed a non-photorealistic rendering method to generate Suibokuga-like images of trees. This method was suitable only for representing trees in Mokkotsuho paintings because the images were generated from three-dimensional skeleton data. In this paper, we propose a method to generate Suibokugalike images of arbitrary objects from three-dimensional geometric models, such as polygonal models. The proposed method realizes Kou, Ten, and Shun brush stroke techniques for creating Sensenbyoho paintings, which are a typical Suibokuga style for representing landscapes. Moreover, the images can be generated from arbitrary viewpoints and light source information. The ability of this method is demonstrated by showing various example.

A stylization method of Chinese ink painting for 3D tree

“…Thus we select tree point clouds as the input. Compared with the methods based on the skeleton model [Zhang et al 1999] and the polygonal model [Sato et al 2004;Way et al 2002], our method is more robust because it is based on raw 3D point clouds of the trees. However, the methods based on the skeleton model and the polygonal model pay more attention to the rendering of trunks and ignore the rendering of leaves that are emphasized in our method.…”

“…It is noted here that the second kind of methods are what we concern about. At present, in the second kind of methods, the given geometric models of trees to be rendered include skeleton model [Zhang et al 1999] and polygonal model [Sato et al 2004;Way et al 2002]. In this paper we firstly present a concise and novel rendering method based on the point clouds tree models, which is another kind of geometric models of trees and could provide more details about trees, in Chinese ink painting stylization.…”

“…The key point of the methods is constructing lots of different strokes of both trees' appearance and Chinese ink painting stylization. Another kind of methods is rendering by using texture mapping or other algorithms on given geometric models of the trees [Sato et al 2004;Way et al 2002;Zhang et al 1999] . It is noted here that the second kind of methods are what we concern about.…”

“…The problem could be handled effectively when rendering on 3D area. Thus it is meaningful to carry out the research work of Chinese ink painting rendering of trees based on 3D area [Sato et al 2004;Way * e-mail:wyh 925@163.com et al 2002;Zhang et al 1999;Chan and Akleman 2002;Li and Yu 2006;Li 2013]. …”

“…Being one of the objects that often appear in Chinese landscapes ink paintings, trees are worth noticing in the Chinese ink painting stylization rendering field [Chu and Tai 2005;He 2008;Li and Yu 2006;Li 2013;Sato et al 2004;Wang and Wang 2007;Xie et al 2011;Yang et al 2012]. …”
