    Three-dimensional metamorphosis (or morphing) establishes a smooth transition from a source object to a target object. The primary issue in 3D metamorphosis is to establish surface correspondence between the source and target objects, by which each point on the surface of the source object maps to a point on the surface of the target object. Having established this correspondence, we can generate ... View full abstract»

    The natural world is rich in complex and beautiful visual phenomena. Many of these are ripe for simulation by computer graphics. The author discusses digital lightning. His aim is to accurately match the natural phenomena, and not simply make something that could pass as an example of it View full abstract»

  • The ambient spaces of computer graphics and geometric modeling

    Publication Year: 2000, Page(s):76 - 84
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (428 KB)

    Four types of ambient mathematical spaces underlie the algebra and geometry of computer graphics and geometric modeling: vector spaces, affine spaces, projective spaces, and Grassmann spaces (H.G. Grassmann, 1894-1911). The author considers at length the theoretical advantages of the coordinate-free approach to understanding geometry. He focuses attention on the operations of addition, subtraction... View full abstract»

  • Choosing rendering parameters for effective communication of 3D shape

    We conducted a series of perceptual experiments to assess the contributions of rendering parameters to the perception of the shape of three-dimensional objects. For the experiments, observers viewed graphically rendered displays consisting of pairs of rotating objects and judged whether their shapes were identical. For some pairs they were, while for other pairs they differed by varying amounts. W... View full abstract»

  • Maya: “So ya wanna be a rock 'n roll star” revisited [animation product]

    In 1995, the company today known as Alias/Wavefront (A/W) held a press conference to announce its next-generation animation product, Maya. A/W claimed this future 3D animation tool would increasingly serve the artist, not the other way around. Maya addressed a basic problem: When artists working at a drafting table reach for a new pencil, they never look away from the part of the drawing they're w... View full abstract»

  • Mosaicing ultrasonic volumes for visual simulation

    Publication Year: 2000, Page(s):53 - 61
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (496 KB)

    The article addresses the problem of mosaicing a large volume from a set of small volumes acquired from a 3D ultrasound device. The formation of large volumes is necessary for an ultrasound visual simulator. Trainees using the simulator learn how to identify and diagnose a wide range of medical cases by operating a simulated ultrasound device on a mannequin, without any need for actual patients. T...

  • Using a flatbed scanner as a stereoscopic near-field camera

    Publication Year: 2000, Page(s):38 - 45
    Cited by:  Papers (5)  |  Patents (1)

    It is shown that flatbed scanners are inherently high quality 3D scanners. Currently developed first prototypes have many applications in industry and multimedia. Because of their big depth of focus, they can be used not only for scanning printed paper, but also for scanning small objects. The nonparallel optics also make it possible to create stereoscopic images of small objects with flatbed scan... View full abstract»

  • Speech/gesture interface to a visual-computing environment

    We developed a speech/gesture interface that uses visual hand-gesture analysis and speech recognition to control a 3D display in VMD, a virtual environment for structural biology. The reason we used a particular virtual environment context was to set the necessary constraints to make our analysis robust and to develop a command language that optimally combines speech and gesture inputs. Our interf... View full abstract»

  • Data signatures and visualization of scientific data sets

    Publication Year: 2000, Page(s):12 - 15

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (220 KB)

    Today, as data sets used in computations grow in size and complexity, the technologies developed over the years to deal with scientific data sets have become less efficient and effective. Many frequently used operations, such as eigenvector computation, could quickly exhaust our desktop workstations once the data size reaches certain limits. On the other hand, the high-dimensional data sets we col... View full abstract»

    The Iowa Communications Network (ICN) is a statewide, state administered, fiber optics network. Iowa State University (ISU) is one of the fiber optics endpoints and one of the main entities using the ICN to reach the Iowa community. As part of the ICN outreach activities at ISU, we are investigating how the ICN can be integrated with our research projects in virtual reality (VR). We're particularl... View full abstract»

  • Morphology-based data elimination from medical image data

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (404 KB)

    Modern medical imaging lets us create accurate computer models of anatomical structures. Some of these models can be animated to visualize joint kinematics. A model's size and complexity can significantly affect the efficiency of any desired animation or interactive manipulation. The model normally takes the form of a polygonal mesh; the more facets in the mesh, the slower the rendering process. B... View full abstract»
