TITLE:Shading Approach for Artistic Stroke Thickness using 2D Light Position * Shading Approach for Artistic Stroke Thickness using 2D Light Position [#xf7ddc92] CENTER:&size(16){''[[Takashi Ejiri>Members/TakashiEjiri]], [[Yuki Morimoto>Members/YukiMorimoto]], [[Tokiichiro Takahashi>Members/TokiichiroTakahashi]]''}; CENTER:&size(16){''ACM SIGGRAPH 2014''}; ~ We present an approach for determining stroke thickness in illustrations based on two-dimensional (2D) light position. Stroke rendering is particularly important for cartoons and illustrations in nonphotorealistic rendering (NPR). In cartoons and illustrations, stroke thickness is varied for effective expressions. ~ [Goodwin et al. 2007] proposed a shading approach to artistic stroke thickness using a three-dimensional (3D) model. However, shading 2D images using 2D light position remains a challenge. ~ We propose a method to render artistic stroke styles by varying thickness considering the distance from a 2D light position. ** Images [#dd787ef6] |#ref(./t-ejiri-2014-08-international_1.png,nolink,center);| ** Tags [#dc9781f9] &tag(Takashi Ejiri,SIGGRAPH); |
