    Animating the drape of different cloths must address complex physical behaviors. This particle approach uses optimizations that make it faster than earlier implementations and allow it to simulate behavior over time. The modeling system presented computes the full trajectories of particles and not just the final positions. This offers several important advantages. Since the full history of each pa...

  • An evolving system for simulating clothes on virtual actors

    Publication Year: 1996, Page(s):42 - 51

    This cloth modeling and animation system aims to support virtual actors who can dress and undress themselves. It now creates autonomous clothes, independent of the synthetic human wearing them. The interactive editor, proportion box and body-scaling feature provide a set of intuitive tools for animators to design a rich variety of human shapes, and we have shown how to dress them with autonomous c...

  • Fun with premultiplied alpha

    The computer graphics universe consists of pixels. Pixels, in turn, consist of components: red, green, blue, and the coverage or opacity value alpha. For various reasons it is convenient to store and process a given rgbα quadruple with the rgb values already multiplied by α. This was first pointed out in the original Porter-Duff compositing paper (1984) and I presented some further jus... View full abstract»

  • 3D scanning in apparel design and human engineering

    Much work remains before 3D anthropometric imaging systems can be used successfully in automated apparel design and other applications requiring accurate human body size data. Furthermore, the development of basic anthropometric data extraction tools and other related application software must be greatly enhanced, regardless of the scanner type or proposed application. Still, based on current prog... View full abstract»

  • It's really not a rendering bug, you see

    Publication Year: 1996, Page(s):21 - 25
    Cited by:  Papers (8)  |  Patents (2)

    Most rendering algorithms deliberately employ approximations and other shortcuts for efficiency. These economies-not coding errors-produce characteristic image artifacts. This article classifies the best-known varieties. We wrote this article in the hope of saving programmers a lot of time debugging something that is really not a bug, but instead a limitation of the algorithm. Our taxonomy is not ...

  • Computer graphics techniques for modeling cloth

    Publication Year: 1996, Page(s):28 - 41

    In this survey, we present a contemporary overview of cloth modeling techniques. 19 modeling techniques are summarized and categorized by their main theoretical method: geometrical, physical, or hybrid. The techniques within each category do not follow well-defined patterns. We therefore generally report each work independently according to the chronology of publication. At the end of the discussi... View full abstract»

  • More origami solids

    Publication Year: 1996, Page(s):81 - 85
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1084 KB)

    There are a bunch of interesting programming projects hiding within the subject of origami, and unit origami in particular. Certainly one of the most straightforward is to write a program that will read some form of origami notation and create a 3D geometry file of the result, which you can then render. Or you can use the same information to create folding diagrams. These are both very hard proble... View full abstract»

  • Visualizing production planning data

    Publication Year: 1996, Page(s):7 - 10

    Visualization of production planning data for decision making in manufacturing is nearly nonexistent. The planning problems at the Electronic Card Assembly and Test plant (ECAT) at IBM Austin, Texas, prompted the research project reported in this article. The project studied the characteristics of this type of managerial data, then developed special visualization techniques for constructing visual... View full abstract»

    If a woven cloth composite “ply” cannot fit a surface exactly, “darts” must be cut. Algorithms that define these darts for a CAD system resolve anomalies in the 3D ply View full abstract»

    Virtual driving environments represent a challenging test for virtual reality technology. We present an overview of our work on the problems of scenario and scene modeling for virtual environments (VEs) in the context of the Iowa Driving Simulator (IDS). The requirements of driving simulation-a deterministic real-time software system that integrates components for user interaction, simulation, and... View full abstract»
