  • Asymmetric tensor analysis for flow visualization 
    Oregon State University. Dept. of Computer Science; Zhang, Eugene; Yeh, Harry Hsiu Jenq; Lin, Zhongzang; Laramee, Robert S. (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2007)
    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 ...
  • Efficient Morse decompositions of vector fields 
    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 ...
  • Efficient Morse decompositions of vector fields 
    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 ...
  • Surface-Based Flow Visualization 
    Edmunds, Matt; Laramee, Robert S.; Chen, Guoning; Max, Nelson; Zhang, Eugene; Ware, Colin (Elsevier, 2012-12)
    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 progres ...
  • Topological analysis and visualization of asymmetric tensor fields 
    Oregon State University. Dept. of Computer Science; Zhang, Eugene; Lin, Zhongzang; Yeh, Harry Hsiu-jen; Laramee, Robert S. (Corvallis, OR : Oregon State University, Dept. of Computer Science, 2007)
    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 ...
  • Topological analysis of asymmetric tensor fields for flow visualization 
    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 ...
  • Vector field editing and periodic orbit extraction using Morse decomposition 
    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 ...
