    Discusses a dot-graphics plotting technique that allows a control system to read voxel data at a constant rate, despite the random-scan nature of the writing method. If we assume the data is arranged in consecutive slices, then the constrained 3D optimization problem reduces to a 2D one. In this article, we investigate and seek to optimize the efficiency with which the voxels within each slice are... View full abstract»

    Few tools exist for the system-level investigation of the nervous system function, just electroencephalography (EEG), functional brain imaging techniques, and large-scale simulation. Of these, simulation has contributed the least to our understanding. We describe the construction and application of a simulation environment that uses visualization as the interface to control and analyze the behavio... View full abstract»

    Offset curves have diverse engineering applications, spurring extensive research on various offset techniques. In a paper on offset curve approximation (Lee et al., 1996), we suggested a new approach based on approximating the offset circle instead of the offset curve itself. To demonstrate the effectiveness of this approach, we compared it extensively with previous methods. To our surprise, Tille... View full abstract»

  • Real-time fluid simulation in a dynamic virtual environment

    Simulating physically realistic complex fluid behaviors in a distributed interactive simulation (DIS) presents a challenging problem for computer graphics researchers. The authors consider how solving the 2D Navier-Stokes equations via a computational fluid dynamics method lets us map surfaces into 3D and achieves realistic real-time fluid surface behaviours View full abstract»

  • Signs of significance [digital displays]

    Because they're so important, signs need to be very clear. Simplicity means that you don't risk having the style of the presentation conflict with the underlying message. Blandness means you avoid contamination or distortion of the message. So a simple, bland sign should be perfectly legible and perfectly boring. If you're careful and clever, you can work in some design as well. In this article, I... View full abstract»

    In immersive virtual environments, our eyes and ears are usually the most important channels of perception. However, you might expect that their creators would include other senses in VEs so as to represent the largest range of stimuli. After all, humans are creatures of many senses and rely upon all of them in day-to-day living. In crafting virtual worlds for exploration, VE developers usually ai... View full abstract»

  • Animals with anatomy

    In general, computer graphics achieves greater realism using methods that simulate the real world rather than ad hoc methods that just appear somewhat realistic. To this end, we need to develop modeling and animation approaches based on anatomical and physiological principles. The method presented in this article models any animal that has a jointed endoskeleton moved by muscles and covered by a f... View full abstract»

    Given the increasing digitization of information, even a casual observer can see the diminishing role that standard paper-based libraries will (and already do) play in education. More students and professionals than ever before access and process information digitally over networks and the Internet. How then should colleges and universities accommodate students whose academic needs not only fluctu... View full abstract»

  • Faking dynamics of ropes and springs

    This article presents a method to model flexible linear bodies: ropes, cords, springs, and the like, for animation production. The resulting models can easily be animated in a manner that convincingly fakes dynamic behavior. The models were animated using the keyframe animation system, which provides traditional spline-based control of the models' animatable parameters View full abstract»

  • A shape synthesizer

    Publication Year: 1997, Page(s):40 - 51
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (252 KB)

    The article discusses a new shape synthesizer that fosters creative 3D modeling of shapes difficult to develop without a computer. It builds on principles from sound synthesis, mapping them directly into 3D geometry. The article focuses on creative and expressive modeling and development rather than faithfully representing manufacturing processes. The modeling environment lets a designer interacti...
