    The purpose of 3D scanning is to bridge the real world with the virtual world. A practical system would not only produce photorealistic models, but would also be inexpensive and easy to use. We took a 3D scanner developer's viewpoint to review different 3D digitizing techniques. We briefly compare existing systems and give special consideration to active optical triangulation-based scanners View full abstract»

    One of the most interesting ways of assembling small units is along one of the lattices that make up crystals. In this column I live entirely in a 2D world, so the crystals are nothing but collections of polygons in the plane. It is well known that there are only three regular polygons that can tile the plane. Here the verb tile means to cover the infinite plane with a set of polygons so that no g... View full abstract»

    As we progress into applications that incorporate interactive life-like 3D computer graphics, the mouse falls short as a user interface device, and it becomes obvious that 3D computer graphics could achieve much more with a more intuitive user interface mechanism. Haptic interfaces, or force feedback devices, promise to increase the quality of human-computer interaction by accommodating our sense ... View full abstract»

    Quantifying physical abnormalities, guiding corrective and plastic surgery, manufacturing clothing, three-dimensional CAD, and other related fields all benefit from the increasing use of 3D scanners. These scanning systems reconstruct a 3D surface as a large set of polygonal meshes. Although Cyberware scanning systems have become a commercial standard, they have two main drawbacks. First, for larg... View full abstract»

    Both the National Research Council (NRC) report “Virtual Reality: Scientific and Technological Challenges” and the more recent NRC report “Modeling and Simulation: Linking Entertainment and Defense” discuss the need for nontraditional degree programs that focus more closely on the issues of how we develop the software and content for networked virtual environments (VEs).

    Often applied to spatial data for decision making purposes, GIS is growing rapidly as information technologies find use in new fields. The paper discusses an alternative user interface designed using a formal mathematical model and human factors engineering. It relies on direct manipulation of icons representing spatial and temporal data layers View full abstract»

    Vision can be a powerful interface device for computers because of its potential for sensing body position, head orientation, direction of gaze, pointing commands, and gestures. Such unencumbered interaction can make computers easier to use. We describe vision algorithms for interactive graphics and present vision-controlled graphics applications using these algorithms. Some applications employ an... View full abstract»

    Over the ages, healers have used imagery of many sorts to understand and explain illness and injury. From the deification of the beings associated with various illnesses to the advent of modern computer-aided imagery, healers have wanted to understand and see what is happening inside of their patients' bodies. I examine the imaging technologies doctors can use now, look at some advances and their ... View full abstract»

    The whole point of doing 3D graphics is the third dimension. Since the screen is only two-dimensional, the third dimension appears only indirectly in terms of perspective and occlusion. Correct occlusion testing is, however, fairly sensitive to precision problems in the depth calculation. I review the traditional way to represent depth and describe a new technique that appears in the new generatio... View full abstract»

    The earliest bit-mapped graphical computers have progressed to bring real-time 3D rendering and digital video to the desktop, but the common physical interface remains unchanged from the first workstations. As a result, many applications, such as modeling or navigating in virtual worlds, are often limited not by processing speed but by the users' difficulty in conveying desired actions to the comp...

    PCs with substantial 3D graphics are arriving on desktops everywhere. It was only a few years ago that people sniggered at PC graphics and laughed out loud at the notion of PCs with robust and versatile operating systems. Now, however, PC operating systems-especially Windows NT-have software development, networking, multiprocessing, and other tools to rival Unix environments. A user or developer c...
