Shading Approach for Artistic Stroke Thickness using 2D Light Position

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.
