    The idea for building a VR model of the NTU campus came about six years ago when the School of Computer Engineering purchased a powerful graphics workstation with advanced modeling software systems, MultiGen-Paradigm's MultiGen and Vega. Three-dimensional Web visualization developed rapidly. Personal computers became capable of making VR walkthroughs even in shared virtual worlds. Cybertown create... View full abstract»

    Theresa-Marie Rhyne has lately been organizing efforts for a number of researchers to produce lists of top visualization problems. This visualization viewpoints column is a look back at the top five problems that drove our work developing Vis5D, Cave5D, and VisAD. Some of these problems are high-minded and some are grubby and gritty. View full abstract»

    First, most graphics articles originate from computer graphics professionals in computer science departments or computer technology companies. Their job is to extend and refine graphics technology itself, and tell us of their progress. Apply computer graphics in a new area. The best applications articles occur when new technologies and equipment allow a new problem domain to benefit from graphics-... View full abstract»

  • Synergistic visual/haptic rendering modes for scientific visualization

    Our approach uses a visual/haptic interface to display scientific data both graphically and haptically. The haptic interface provides a natural means of interacting with the data through direct tactile sensing and manipulation of the data display. Our experience with this interface suggests that users understand the data more clearly when the haptic component acts as a synergistic companion to the... View full abstract»

  • Touch-based haptics for interactive editing on point set surfaces

    A modeling paradigm for haptics-based editing on point set surfaces exploits implicit surfaces, physics-based modeling, point-sampled surfaces, and haptic. We propose a point-based geometry representation that we initially designed for dynamic physics-based sculpting, but can easily generalize to other relevant applications such as data modeling and human-computer interaction. By extending the ide... View full abstract»

  • Evaluation of drawing on 3D surfaces with haptics

    We describe experiments for evaluating the speed and accuracy of a haptic drawing interface, particularly in terms of the effects of changing two haptic characteristics the magnitude of the friction force and the use of smooth, interpolated-normal force shading in combination with the effect of stereo displays and shadows. Because surface geometry affects the sense of touch, we studied the efficac... View full abstract»

    Haptic state-surface interaction techniques, which encode modes into force states, make interactions with 3D objects more fluid and natural. Our techniques comprise only a subset of those necessary to support a fully functional haptic application with capabilities similar to a drawing program such as Adobe Illustrator. However, these techniques can potentially simplify some common operations, such... View full abstract»

    We focus on the realism/transparency aspect of haptic rendering. We introduce a novel approach that enables physically correct and accurate simulation of contact wrench Wc for general rigid objects in real time, taking into account not only friction and gravity but also dynamic effects. Our method for contact force and moment simulation builds on the real-time identification of geometri... View full abstract»

    The virtual reality for maintainability (Revima) VR system supports maintainability simulation in aeronautics. Within this project we have developed and integrated a haptic device, the large haptic interface for aeronautic maintainability (LHIfAM). We use this device to track hand movements and provide force feedback within the large geometric models that describe aircraft engines. The user moveme... View full abstract»

    We present a much easier way to capture the geometric structure of many Crop circle formations, using a special-purpose language. There are three distinct types of objects in Crop: scalars (floating-point or integer numbers), points (represented by pairs of numbers), and objects (circles, ellipses, and polygons). In this paper we label variables starting with the letters s, p, or o to identify the... View full abstract»
