    We present a rule-based approach combined with traditional geometric modelling techniques that allows easy generation of many branching objects including flowers, bushes, trees, and even nonbotanical objects. A set of components describing structural and geometrical elements of plants maps to a graph that forms the description of a specific plant and generates the geometry. Users get immediate fee...

    We introduce and investigate the fundamental similarities and differences of watermarking 3D graphic models compared to 2D images, and propose some solutions to address a class of applications of digital watermarking-the verification of 3D polygonal models. To our knowledge, watermarking of 3D objects for verification purposes has not been addressed in any published literature. The proposed scheme... View full abstract»

    Digital watermarking has been increasingly applied to hide information in digital multimedia data, thus enlisting the watermarking technology in the difficult fight against intellectual property rights infringement. The authors have developed a secure, robust watermarking algorithm and applied it in digital streaming MPEG-2 format video-the format of choice in the broadcast and video stock industr...

    We explain how to use color under the constraints of a window system for three types of applications, discussing each topic in parallel for the X Window System and Microsoft Windows. The focus is on displaying images with special attention to color fidelity, discussing techniques for keeping a consistent appearance between applications, and device portability issues View full abstract»

    Digital watermarks offer a way to counter copyright piracy on the global network. We summarize the fundamental concepts of watermarking and describe a general framework for a copyright protection system. Watermarks efficiently protect copyright when basic demands can be satisfied. However, the demand for watermarks to remain robust under digital image-processing operations has not yet been fully s... View full abstract»

    This article addresses the modeling aspects of macrostructured texture synthesis often avoided by other methods. We aim to develop a system that provides an intuitive, interactive, continuous, and easy-to-use control to users during the entire synthesis process. Therefore, we propose efficient new solutions for the following four problems: interactive and easy control of the macrostructure attribu... View full abstract»

    Polygons are everywhere, but one place the author didn't expect to see polygons is in the Fourier transform, but he found them there as well. The Fourier transform is an indispensable tool in signal processing. In computer graphics, it helps us understand and cure problems as diverse as jaggies on the edge of polygons, blocky looking textures, and animated objects that appear to jump erratically a...

    Michelangelo carved his Florentine Pieta, the second of three Pieta statues, from a single block of marble while in his 70s. The piece includes posed figures of Christ in the arms of the Virgin Mary, Nicodemus (properly Joseph of Arimathea) looking on, and Christ touching Mary Magdelene. The statue was thought to be for the artist's tomb. Two years after he had stopped working on the unfinished pi... View full abstract»

    In 1997 the US Army's Simulation, Training, and Instrumentation Command (STRICOM), recognizing the increasingly attractive economies of scale associated with PC 3D rendering technology, awarded a contract to the University of Central Florida's Institute for Simulation and Training (IST) to study the suitability of PCs for military real-time visual simulation (VisSim). The result was the Low-Cost V... View full abstract»
