    If you're into computer graphics, you have to love matrices, but sometimes matrices are so complicated. They have determinants, eigenvalues, singular value decompositions... . What does all this stuff really mean? What does it mean, for example, to take the square root of a matrix? How about the logarithm of a matrix? I have built up my intuition about matrices by playing extensively with the simp... View full abstract»

    Dramatic changes prompted by the growing global Internet affect how users deal with information. We are passing from a world in which a few devotees managed information to an environment in which many people consume widespread, diffuse information. Along with the excitement comes the recognition that information consumers need effective and efficient tools. Together with unstructured information-s... View full abstract»

  • Visualization in propositional logic

    Publication Year: 1996, Page(s):6 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (336 KB)

    We are visually exploring a current problem in propositional logic related to information processing, specifically n-traces. Traces represent subsets of possible consequences which can be inferred classically from partitions of the set of inputs. We are interested in the relationship between a given set of Boolean inputs and its respective trace(s). Let Σ be a set of sentences or data. In pa... View full abstract»

  • Animating human locomotion with inverse dynamics

    Publication Year: 1996, Page(s):50 - 59
    Cited by:  Papers (43)  |  Patents (6)

    Because the major force components (the internal muscular forces and torques) are not known a priori over time, you cannot use forward dynamics to predict how the human body will walk. The alternative to the apparently intractable problem of specifying the joint torque patterns in advance is to use inverse dynamics to analyze the torques and forces required for the given motion. Such an analysis c... View full abstract»

    Looks at some practical approaches to improving the process of interacting with information distributed over the global information infrastructure, specifically for the World Wide Web. The introduction of NCSA Mosaic changed the way we get information over the Web. With the click of a button, Mosaic's graphical user interface made it possible to browse and retrieve literally any information access... View full abstract»

    If you have any interest in meteorology, you can learn a lot by trawling the World Wide Web. As with other subjects, it presents a wealth of in-depth data; a modem is the key to the previously inaccessible ivory tower of knowledge. You can get weather data and images that you can't get from TV or newspapers, and you can do it when you want rather than waiting for a newscast or newspaper edition. Y... View full abstract»

  • Visualizing retrieved information: a survey

    Clearly, the presentation method for information retrieved from the global information infrastructure (GII) makes a big difference to users. The NCSA Mosaic interface, for example, with its point-and-click multimedia page presentation, swelled popular interest in the World Wide Web. This experience suggests the possibility of increased usefulness if we apply visualization techniques to information... View full abstract»

    As computer-based video becomes ubiquitous with the expansion of transmission, storage, and manipulation capabilities, it will offer a rich source of imagery for computer graphics applications. This article looks at one way to use video as a new source of high-resolution, photorealistic imagery for these applications. If you walked through an environment, such as a building interior, and filmed a ... View full abstract»

  • Parameterized gait synthesis

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3272 KB)

    This article presents a method of producing gaits by using control mechanisms analogous to windup toys. The synthesis technique is based on optimization. One of the primary characteristics of “virtual windup toys” is that they are oblivious to their environment. This means that these creatures or simulated toys have no active control over balance. Nevertheless, “blind” para... View full abstract»

    A fundamental aspect of information visualization involves the display of relationships among objects. Much of this information can be represented by networks with nodes corresponding to objects and links representing their relationships. Node and link diagrams, although natural choices to display this class of data, are easily overwhelmed with too much information, becoming cluttered and visually... View full abstract»

    A new paradigm for designing complex engineering systems has emerged from computer graphics and CAD/CAM technology. Virtual design environments allow users to design and visualize all stages of the product. They not only free designers from the two dimensions of pencil and paper but also eliminate costly construction of physical mock-ups. We are developing the necessary technology for interactive ...

  • The role of computer graphics and visualization in the GII

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (340 KB)

    However captivating and encouraging its potential, the global information infrastructure (GII) has a long way to go before reaching full effectiveness. The GII must address real user needs and capabilities rather than developers' opinions on them. Otherwise, this information universe will become a cemetery, a massive burial site for an infinitely large amount of data and information. Visualization... View full abstract»

    Describes a technique for creating dot patterns that approximate solar phenomena such as sun dogs and solar halos. I extend the simulation to include energy considerations, smooth images and color. I present a summary of the basic process for creating the dot patterns. We start by imagining a perfectly hexagonal ice crystal, which may be thin compared with its radius (in which case we call it a pl... View full abstract»

    Computer-generated images without depth-of-field effects always look surreal. A new technique and algorithm are presented which solve the problem of simulating these effects in VR and other real-time applications. The adaptive convolution approach can generate depth-of-field effects in real time using commercially available hardware filters. The picture-processing algorithm proposed can be easily ...

  • Put: language-based interactive manipulation of objects

    Our approach to scene generation capitalizes the expressive power of natural language by separating its aptness in specifying spatial relations from the difficulties of understanding text. We are implementing an object-placement system called Put that uses a combination of linguistic commands and direct manipulation. The system is language-based, meaning that its design and structure are guided by... View full abstract»
