Stylized line rendering for three-dimensional models

Line rendering is an important issue in the field of Non-Photorealistic Rendering. How to use lines to describe the features of 3D models properly has long been a challenging goal for researchers, especially when some artistic rules have to be obeyed. In this article, a new method has been proposed for illustrating loose line style. We proposed a mathematical model according to the features of loose lines, our main work focus on three aspects as follows: silhouette artistic thickness performance, silhouette loose style display, and the temporal coherence of line texture performance.
