    For large-scale visualization applications, the visualization community urgently needs general solutions for efficient parallel I/O. These parallel visualization solutions should center around design patterns and the related data-partitioning strategies, not file formats. From this respect, it's feasible to greatly alleviate I/O burdens without reinventing the wheel. For example, BIL (Block I/O La... View full abstract»

    Tree visualization is one of the best-studied areas of information visualization; researchers have developed more than 200 visualization and layout techniques for trees. The treevis.net project aims to provide a hand-curated bibliographical reference to this ever-growing wealth of techniques. It offers a visual overview that users can filter to a desired subset along the design criteria of dimensi... View full abstract»

    This tutorial provides a starting point for curve-based modeling. It introduces three rough categories of curve-based-modeling methods: extruding 2D shapes, inflating 2D shapes, and drawing 3D curves. This tutorial introduces representative methods that yield positive results while also exposing several issues related to curve-based modeling. View full abstract»

    Sketching on paper is a quick and easy way to communicate ideas. However, many sketch-based systems require people to draw in contrived ways instead of sketching freely as they would on paper. NaturaSketch affords a more natural interface through multiple strokes that overlap, cross, and connect. It also features a meshing algorithm to support multiple strokes of different classifications, which l... View full abstract»

  • Large-Scale Physics-Based Terrain Editing Using Adaptive Tiles on the GPU

    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (12780 KB) | HTML iconHTML Multimedia Media

    Physics-based approaches could simplify terrain modeling by increasing its realism. However, most simulations provide only a low level of user control because they fail on large-scale phenomena or focus only on the modeling of limited effects. A new physics-based system for digital terrain editing is suitable for digital-content authors such as game designers, artists, and 3D modelers. It doesn't ... View full abstract»

    Interest has been growing in the behavioral animation of autonomous actors in virtual worlds. However, authoring complicated interactions between multiple actors in a way that balances control flexibility and automation remains a considerable challenge. A proposed behavior-authoring framework gives users complete control over the domain of the system: the state space, action space, and cost of exe... View full abstract»

    Photosketcher is an interactive system for progressively synthesizing novel images using only sparse user sketches as input. Photosketcher works on the image content exclusively; it doesn't require keywords or other metadata associated with the images. Users sketch the rough shape of a desired image part, and Photosketcher searches a large collection of images for it. The search is based on a bag-... View full abstract»

    Researchers have used depth images to approximate scene geometry in a variety of interactive 3D graphics applications. Previous researchers constructed images using orthographic or perspective projection, which limits the approximation quality to what's visible along a single view direction or from a single viewpoint. Images constructed with nonpinhole cameras can improve approximation quality at ... View full abstract»

    Researchers have studied brain injury in children by assessing linear and angular accelerations, without taking into account vibratory loads. A proposed approach employs a new mathematical head model that includes vibration to analyze how shaken-baby syndrome affects babies. To account for vibrations, it applies the finite-element method to model the stresses, strains, and displacements in the nec... View full abstract»
