Abstract:: This paper addresses the problem of interactively modeling large street networks. We introduce a modeling framework that uses tensor fields to guide the generation of a street graph. A user can interactively edit a street graph by either modifying the underlying tensor field or by changing the graph directly. This...

Creator:: Oregon State University. Dept. of Computer Science, Neill, Patrick J., Metoyer, Ronald A., 1971-, and Zhang, Eugene
Abstract:: Fluid simulation on interacting deformable surfaces is a challenging problem that has many applications. In this paper, we present a framework in which artistic as well as physically realistic flows can be generated on surfaces during deformation and collision. Our simulation system provides comprehensive control over the motion and deformation...

Creator:: Oregon State University. Department of Computer Science, Zhang, Eugene, Yeh, Harry Hsiu Jen, Lin, Zhongzang, and Laramee, Robert S.
Abstract:: Most existing flow visualization techniques focus on the analysis and visualization of the vector field that describes the flow. In this paper, we employ a rather different approach by performing tensor field analysis and visualization on the gradient of the vector field, which can provide additional and complementary information to...

Creator:: Oregon State University. Department of Computer Science, Zhang, Eugene, Lin, Zhongzang, Yeh, Harry Hsiu-jen, and Laramee, Robert S.
Abstract:: Visualizing asymmetric tensors is an important task in understanding fluid dynamics. In this paper, we describe topological analysis and visualization techniques for asymmetric tensor fields on surfaces based on analyzing the impact of the symmetric and antisymmetric components of the tensor field on its eigenvalues and eigenvectors. At the core...

Creator:: Oregon State University. Department of Computer Science, Zhang, Eugene, Yeh, Harry Hsiu Jen, Lin, Zhongzang, and Laramee, Robert S.
Abstract:: The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight into the vector field that is difficult to infer from traditional trajectory-based vector field visualization techniques. We describe the structures in the eigenvalue and eigenvector fields of the gradient tensor and how these...
