    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 techn ...
  • Oregon State University. Dept. of Computer Science; Chen, Guoning; Mischaikow, Konstantin Michael; Laramee, Robert S.; Zhang, Eugene (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2007)
    Existing topology-based vector field analysis techniques rely on the ability to extract the individual trajectories such as fixed points, periodic orbits and separatrices which are sensitive to noise and errors introduce ...
  • Oregon State University. Dept. of Computer Science; Chen, Guoning; Mischaikow, Konstantin Michael; Laramee, Robert S.; Zhang, Eugene (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2007)
    Vector field analysis plays a crucial role in many engineering applications, such as weather prediction, tsunami and hurricane study, and airplane and automotive design. Existing vector field analysis techniques focus on ...
  • Palacios, Jonathan; Yeh, Harry Hsiu-jen; Wang, Wenping; Laramee, Robert S.; Vincent, Paul; Zhang, Eugene (Corvallis, OR : School of Electrical Engineering and Computer Science, Oregon State University, 2013)
    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 f ...

    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 analyzin ...
  • Oregon State University. Dept. of Computer Science; Zhang, Eugene; Yeh, Harry Hsiu Jen; Lin, Zhongzang; Laramee, Robert S. (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2007)
    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 an ...
  • Oregon State University. School of Electrical Engineering and Computer Science; Chen, Guoning; Mischaikow, Konstantin Michael; Laramee, Robert S.; Pilarczyk, Pawel; Zhang, Eugene (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2006)
    Design and control of vector fields is critical for many visualization and graphics tasks such as vector field visualization, fluid simulation, and texture synthesis. The fundamental qualitative structures associated wit ...
