Real-Time Line Rendering Using 2D Curvature

Abstract

In the inking process of cartoon rendering, the line was given change and the method of changing the thickness of the line was developed. For representation of the cartoon graphics like hand-drawn animation, the method of changing the thickness of the line by the curvature like a pencil line was developed. However, sometimes the method didn't match projection coordinate curvature because it used 3D model curvature. In this paper, we developed the method compute 2D curvature of each line, and it drew line which thickness changes with each 2D curvature in real-time.
