    Haptic rendering allows users to "feel" virtual objects in a simulated environment. We survey current haptic systems and discuss some basic haptic-rendering algorithms. In the past decade we've seen an enormous increase in interest in the science of haptics. Haptics broadly refers to touch interactions (physical contact) that occur for the purpose of perception or manipulation of objects. These in... View full abstract»

    A platform-independent occlusion culling library for dynamic environments, dPVS, can benefit such applications as CAD and modeling tools, time-varying simulations, and computer games. Visibility optimization is currently the most effective technique for improving rendering performance in complex 3D environments. The primary reason for this is that during each frame the pixel processing subsystem n... View full abstract»

  • A haptic-rendering technique based on hybrid surface representation

    Publication Year: 2004, Page(s):66 - 75

    A novel haptic rendering technique using a hybrid surface representation addresses conventional limitations in haptic displays. A haptic interface lets the user touch, explore, paint, and manipulate virtual 3D models in a natural way using a haptic display device. A haptic rendering algorithm must generate a force field to simulate the presence of these virtual objects and their surface properties... View full abstract»

    Haptics is a valuable tool in minimally invasive surgical simulation and training. We discuss important aspects of haptics in MISST, such as haptic rendering and haptic recording and playback. Minimally invasive surgery has revolutionized many surgical procedures over the last few decades. MIS is performed using a small video camera, a video display, and a few customized surgical tools. In procedu... View full abstract»

    The program of scientific investigations planned in the framework of the restoration of Michelangelo's David produced several useful guidelines for defining and developing innovative ways to process and visualize 3D data in cultural heritage applications. Our ultimate goal was to include 3D graphics among the tools which can help restorers select the proper restoration procedures for the task at h... View full abstract»

    New sophisticated haptic-rendering algorithms let users experience virtual objects through touch. We systematically investigate the unrealistic behavior of virtual haptic textures. The emerging science of haptic rendering consists of delivering properties of physical objects through the sense of touch. Owing to the recent development of sophisticated haptic-rendering algorithms, users can now expe... View full abstract»

    Developed with optimization and access as its central tenets, the simulation aimed originally to simulate a biologically diverse landscape (initially tropical islands) and simulate the ape inhabitant's cognitive processes. The cognitive simulation relies on two competing 3D mathematical effects to describe two basic cognitive effects - fear and desire. The simulation creates a rich ecological envi...

    Particle Flurries is an interactive approach to 3D flow visualization. The approach produces a "synoptic visualization" and is used to examine both internal and external flows. Synoptic visualizations give viewers a synopsis of all flow features simultaneously. Good examples of 2D synoptic visualizations are weather maps from both TV news reports and online Web pages. The human visual system is ad... View full abstract»

    The StorySpace project studies the role new interface technologies might play in high school education. With this approach in mind, StorySpace is specifically designed to support and enhance classroom narrative, an already well-established classroom activity. StorySpace strives to achieve this through adherence to three design goals. The first is to trigger student reflection and interpretation. T... View full abstract»

    We survey the haptics literature and identify conditions under which haptic interaction displays can enhance human perception and performance. Integrating haptic interactions in multimodal systems requires understanding user's sensory, perceptual, and cognitive abilities and limitations. Haptic design guidelines can aid developers of multimodal interactive systems. Haptic interaction relates to al... View full abstract»

    A method for synthesizing the haptic response of nonlinear deformable objects from data obtained by offline simulation helps create surgical simulators with high-fidelity haptic feedback. Haptic displays provide users with artificially created tactile sensations. One important use of these displays is to recreate the experience caused by contact between a tool and an object. This capability can be... View full abstract»

    Everybody loves making pictures with a spirograph. Spirograph produces planar curves that are known as roulettes. The simplest way to create a roulette is probably to use a circle for the wheel and a straight line for the frame. This results in a figure that has the special name cycloid. Spirograph only has a few curve types available. To make other types of curves, it might be useful to attach a ... View full abstract»
