Vector fluid: a vector art representation of fluid

We present a new approach for rendering fluid with a style of vector graphics. The proposed method of vector art rendering of fluid exhibits a curly, beautiful and clear silhouette which deserves artistic expression. (See Figure 1) In computer vision, fluid has been mainly focused on capturing realistic behavior. Thanks to the much contribution of seminal works, large knowledge of photorealistic rendering of fluid have been amassed. On the other hand, although some approaches of the artistic rendering of fluid proposed [Selle et al. 2004; Eden et al. 2007], it seems that the area is not researched intensively and this kind of rendering technique still remains untouched. In order to achieve vector art rendering, we have to track the target region in fluid. However, popular methods of tracking interface model fluid with density field or collection of particles which introduce sudden topological changes and it is challenging to track them precisely. Instead, we consider the velocity field is infinitely continuous so that none of the part of fluid contour intersects each other at any state. Even though such consideration is questionable in physically derived model, this concept of non-intersection of contour leads a very simple algorithm and exhibits nice results. In this paper we first briefly describe the algorithm for vector fluid rendering and secondly we show some artworks created by our method to demonstrate the potential of our algorithm.
