Creator:: Chen, Yongshuai, Zhang, Eugene, and Yeh, Harry
Abstract:: In the companion paper (Chen & Yeh, J. Fluid Mech., vol. 749, 2014, pp. 577–596), collisions of counter-propagating solitary waves were studied experimentally by analysing the measured water-surface variations. Here we study the flow fields associated with the collisions. With the resolved velocity data obtained in the laboratory, the flow...

Creator:: Chi, Ming-Te, Yao, Chih-Yuan, Zhang, Eugene, and Lee, Tong-Yee
Abstract:: Illusory motions refer to the phenomena in which static images composed of certain colors and patterns lead to the illusion of motions. This paper presents an approach for generating illusory motions on 3D surfaces which can be used for shape illustration as well as artistic visualization of line fields on...

Creator:: Palacios, Jonathan, Yeh, Harry Hsiu-jen, Wang, Wenping, Laramee, Robert S., Vincent, Paul, and Zhang, Eugene
Abstract:: Three-dimensional symmetric tensor fields have a wide range of applications in solid and fluid mechanics. Recent advances in the topological analysis of 3D symmetric tensor fields focus on the local behaviors of tensor fields at degenerate points, which usually form curves. In this paper, we make a number of observations...

Creator:: Zheng, Youyi, Tai, Chiew-Lan, Zhang, Eugene, and Xu, Pengfei
Abstract:: This paper introduces a simple yet effective shape analysis mechanism for geometry processing. Unlike traditional shape analysis techniques which compute descriptors per surface point up to certain neighborhoods, we introduce a shape analysis framework in which the descriptors are based on pairs of surface points. Such a pairwise analysis approach...

Creator:: Edmunds, Matt, Laramee, Robert S., Chen, Guoning, Max, Nelson, Zhang, Eugene, and Ware, Colin
Abstract:: With increasing computing power, it is possible to process more complex fluid simulations. However, a gap between increasing data size and our ability to visualize them still remains. Despite the great amount of progress that has been made in the field of flow visualization over the last two decades, a...

Creator:: Chen, Guoning, Kwatra, Vivek, Wei, Li-Yi, Hansen, Charles D., and Zhang, Eugene
Abstract:: Design of time-varying vector fields, i.e., vector fields that can change over time, has a wide variety of important applications in computer graphics. Existing vector field design techniques do not address time-varying vector fields. In this paper, we present a framework for the design of time-varying vector fields, both for...

Creator:: Szymczak, Andrzej and Zhang, Eugene
Abstract:: In this paper, we introduce a new approach to computing a Morse decomposition of a vector field on a triangulated manifold surface. The basic idea is to convert the input vector field to a piecewise constant (PC) vector field, whose trajectories can be computed using simple geometric rules. To overcome...
