Vector field editing and periodic orbit extraction using Morse decomposition

Creator:: Chen, Guoning, Mischaikow, Konstantin Michael, Laramee, Robert S., Pilarczyk, Pawel, Zhang, Eugene, and Oregon State University. School of Electrical Engineering and Computer Science
Abstract:: 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 with vector fields are fixed points, periodic orbits, and separatrices. In this paper we provide a new technique that allows for...

Topological analysis, visualization, and design of vector fields on surfaces

Creator:: Chen, Guoning
Abstract:: Analysis, visualization, and design of vector fields on surfaces have a wide variety of major applications in both scientific visualization and computer graphics. On the one hand, analysis and visualization of vector fields provide critical insights to the flow data produced from simulation or experiments of various engineering processes. On...

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...

Painterly rendering using space-time varying style parameters

Creator:: Kagaya, Mizuki
Abstract:: Automatic painterly rendering systems have been proposed but they opted for selecting a single style to generate paintings from images, which lacks the ability of creatively using multiple styles to focus important objects and deemphasize unimportant part of the scenes. We provide a multi-style painting framework to address this issue...

Surface-Based Flow Visualization

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...

Interactive tensor field design and visualization on surfaces

Creator:: Zhang, Eugene, Hays, James H., Turk, Greg, and Oregon State University. Department of Computer Science
Abstract:: Designing tensor fields in the plane and on surfaces is a necessary task in many graphics applications, such as painterly rendering, pen-and-ink sketch of smooth surfaces, and anisotropic remeshing. In this paper, we present an interactive design system that allows a user to create a wide variety of surface tensor...

Information space mapping with adaptive multiplicatively weighted Voronoi diagrams

Creator:: Trubin, Stanislav I.
Abstract:: Traditional application of Voronoi diagrams for space partitioning creates Voronoi regions, with areas determined by the generators’ relative locations and weights. Especially in the area of information space (re)construction, however, there is a need for inverse solutions; i.e., finding weights that result in regions with predefined areas. In this thesis,...

Visualization in environmental science

Creator:: Winters, Kirsten M.
Abstract:: The VISualization of Terrestrial and Aquatic Systems (VISTAS) software development project began with the proposition that visualization would increase the ability of scientists to explore and communicate their data, especially complex datasets that span multiple spatial and temporal scales. A case study of VISTAS articulates how and why scientists intend...

Design of 2D Time-Varying Vector Fields

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...

Asymmetric tensor visualization with glyph and hyperstreamline placement on 2D manifolds

Creator:: Palke, Darrel, Chen, Guoning, Lin, Zhongzang, Yeh, Harry, Laramee, Robert, and Zhang, Eugene
Abstract:: Asymmetric tensor fields present new challenges for visualization techniques such as hyperstreamline placement and glyph packing. This is because the physical behaviors of the tensors are fundamentally different inside real domains where eigenvalues are real and complex domains where eigenvalues are complex. We present a hybrid visualization approach in which...
