Asymmetric tensor analysis for flow visualization

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...

Topological analysis of asymmetric tensor fields for flow visualization

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...

Tensor Field Design and Analysis for Applications in Computer Graphics and Scientific Visualization

Creator:

Palacios, Jonathan

Abstract:

Many applications in computer graphics and geometry processing rely on the ability to locally orient 2D and 3D entities on a surface, or inside a volume, such as the sinusoidal kernels in Gabor noise, the color and geometry textures in pattern synthesis, and the finite elements in remeshing. In these...
