    We discuss about industrial augmented reality. Each industrial process imposes its own peculiar requirements. This creates the need for specialized technical solutions, which in turn poses new sets of challenges. Because most industries must concern themselves with at least some of these industrial procedures, we consider design, commissioning, manufacturing, quality control, training, monitoring ...

    Visualization has fueled the growth and understanding of many scientific and engineering fields. In computational fluid dynamics, for example, engineers now use numerical calculations to accurately simulate many engineering problems that once required the use of physical experiments involving wind and water tunnels. CFD has come to serve as an instrument in the design of many familiar engineering ... View full abstract»

    Capturing the appearance of objects under different lighting conditions is useful in texture acquisition, bidirectional reflectance distribution function (BRDF) measurement, and image-based data acquisition. With the acquired data, we can render virtual objects realistically. During the data capture, we must record both the radiance and the light vector. Measuring the light vector is not necessari...

    Color is one of the basic building blocks of image creation, yet many computer-based methods for selecting and working with colors remain unchanged from the time of their invention two decades ago. Although some advanced color tools are available for specific tasks, such as color correction, virtually none exist to help users select a set of colors and work with them effectively. The author's tool... View full abstract»

    Digital products are easy to copy, reproduce, and maliciously process in a network environment. Over the past decade, watermarking has emerged as an important technology for protecting copyright of multimedia products. We present a method for embedding and detecting watermarks in vector graphics images containing polygonal lines, and present results from simulated attacks. Our proposed algorithm e...

    Interactive scene walkthroughs have long been an important computer graphics application area. More recently, researchers have developed techniques for constructing photorealistic 3D architectural models from real-world images. We present an image-based rendering system that brings us a step closer to a compelling sense of being there. Whereas many previous systems have used still photography and ... View full abstract»

    Changing an object's appearance by adding geometric details is desirable in many real-world applications. Bump mapping has acted as an alternative to adding geometrical details, to an otherwise smooth object. But constructing visually interesting bump maps requires practice and artistic skills. Computer vision techniques have helped for modeling real-world objects and their surface details. In our... View full abstract»

    Polygons are a ubiquitous modeling primitive in computer graphics. However, modeling with polygons is problematic for highly faceted approximations to smooth surfaces. The sheer size of these approximations makes them impossible to manipulate directly. Subdivision solves this problem by representing a smooth shape in terms of a coarse polygonal model. The subdivision rules used during this refinem... View full abstract»

    To make a synthetic picture with computer graphics, we usually imagine a camera of some sort, taking a picture of a scene. Such cameras range from the simplest pinhole camera to a sophisticated simulation of optics and shutters. We explore some interesting, alternative imaging models - such as digital cubism. We harness the possibilities for communicating ideas and story points in new and expressi... View full abstract»

    A hyperbolic paraboloid is a rather fancy name for a second-order surface more commonly called a saddle point. Three mutually skew lines in space K,L and M determine a unique hyperbolic paraboloid in which they are all embedded. We discuss about the construction of two-and three-line construction geometry. The implicit equation and the parametric equation for one of the two families of embedded li... View full abstract»

    Many cultural heritage applications require 3D reconstruction of real-world objects and scenes. Over the past few years, it has become increasingly common to use 3D digitization and modeling for this purpose. This is mainly due to advances in laser-scanning techniques, 3D modeling software, image-based modeling techniques, computer power, and virtual reality. Our approach integrates several techno...
