3D Graphics Fundamentals
11BegGameDev.qxd 9/20/04 5:20 PM Page 211 chapter 11 3D Graphics Fundamentals his chapter covers the basics of 3D graphics. You will learn the basic concepts so that you are at least aware of the key points in 3D programming. However, this Tchapter will not go into great detail on 3D mathematics or graphics theory, which are far too advanced for this book. What you will learn instead is the practical implemen- tation of 3D in order to write simple 3D games. You will get just exactly what you need to 211 11BegGameDev.qxd 9/20/04 5:20 PM Page 212 212 Chapter 11 ■ 3D Graphics Fundamentals write a simple 3D game without getting bogged down in theory. If you have questions about how matrix math works and about how 3D rendering is done, you might want to use this chapter as a starting point and then go on and read a book such as Beginning Direct3D Game Programming,by Wolfgang Engel (Course PTR). The goal of this chapter is to provide you with a set of reusable functions that can be used to develop 3D games. Here is what you will learn in this chapter: ■ How to create and use vertices. ■ How to manipulate polygons. ■ How to create a textured polygon. ■ How to create a cube and rotate it. Introduction to 3D Programming It’s a foregone conclusion today that everyone has a 3D accelerated video card. Even the low-end budget video cards are equipped with a 3D graphics processing unit (GPU) that would be impressive were it not for all the competition in this market pushing out more and more polygons and new features every year. -

Progressive Imagery with Scalable Vector Graphics -..:: VCG Rostock
Progressive imagery with scalable vector graphics Georg Fuchsa, Heidrun Schumanna, and Ren´eRosenbaumb aUniversity of Rostock, Institute for Computer Science, 18051 Rostock, Germany; bUC Davis, Institute of Data Analysis & Visualization, Davis, CA 95616 U.S.A. ABSTRACT Vector graphics can be scaled without loss of quality, making them suitable for mobile image communication where a given graphics must be typically represented in high quality for a wide range of screen resolutions. One problem is that file size increases rapidly as content becomes more detailed, which can reduce response times and efficiency in mobile settings. Analog issues for large raster imagery have been overcome using progressive refinement schemes. Similar ideas have already been applied to vector graphics, but an implementation that is compliant to a major and widely adopted standard is still missing. In this publication we show how to provide progressive refinement schemes based on the extendable Scalable Vector Graphics (SVG) standard. We propose two strategies: decomposition of the original SVG and incremental transmission using (1) several linked files and (2) element-wise streaming of a single file. The publication discusses how both strategies are employed in mobile image communication scenarios where the user can interactively define RoIs for prioritized image communication, and reports initial results we obtained from a prototypically implemented client/server setup. Keywords: Progression, Progressive refinement, Scalable Vector Graphics, SVG, Mobile image communication 1. INTRODUCTION Vector graphics use graphic primitives such as points, lines, curves, and polygons to represent image contents. As those primitives are defined by means of geometric coordinates that are independent of actual pixel resolutions, vector graphics can be scaled without loss of quality. -

An Online System for Classifying Computer Graphics Images from Natural Photographs
An Online System for Classifying Computer Graphics Images from Natural Photographs Tian-Tsong Ng and Shih-Fu Chang fttng,[email protected] Department of Electrical Engineering Columbia University New York, USA ABSTRACT We describe an online system for classifying computer generated images and camera-captured photographic images, as part of our effort in building a complete passive-blind system for image tampering detection (project website at http: //www.ee.columbia.edu/trustfoto). Users are able to submit any image from a local or an online source to the system and get classification results with confidence scores. Our system has implemented three different algorithms from the state of the art based on the geometry, the wavelet, and the cartoon features. We describe the important algorithmic issues involved for achieving satisfactory performances in both speed and accuracy as well as the capability to handle diverse types of input images. We studied the effects of image size reduction on classification accuracy and speed, and found different size reduction methods worked best for different classification methods. In addition, we incorporated machine learning techniques, such as fusion and subclass-based bagging, in order to counter the effect of performance degradation caused by image size reduction. With all these improvements, we are able to speed up the classification speed by more than two times while keeping the classification accuracy almost intact at about 82%. Keywords: Computer graphics, photograph, classification, online system, geometry features, classifier fusion 1. INTRODUCTION The level of photorealism capable by today’s computer graphics makes distinguishing photographic and computer graphic images difficult. -
Graphics Formats and Tools
Graphics formats and tools Images à recevoir Stand DRG The different types of graphics format Graphics formats can be classified broadly in 3 different groups -Vector - Raster (or bitmap) - Page description language (PDL) Graphics formats and tools 2 Vector formats In a vector format (revisable) a line is defined by 2 points, the text can be edited Graphics formats and tools 3 Raster (bitmap) format A raster (bitmap) format is like a photograph; the number of dots/cm defines the quality of the drawing Graphics formats and tools 4 Page description language (PDL) formats A page description language is a programming language that describes the appearance of a printed page at a higher level than an actual output bitmap Adobe’s PostScript (.ps), Encapsulated PostScript (.eps) and Portable Document Format (.pdf) are some of the best known page description languages Encapsulated PostScript (.eps) is commonly used for graphics It can contain both unstructured vector information as well as raster (bitmap) data Since it comprises a mixture of data, its quality and usability are variable Graphics formats and tools 5 Background Since the invention of computing, or more precisely since the creation of computer-assisted drawing (CAD), two main professions have evolved - Desktop publishing (DTP) developed principally on Macintosh - Computer-assisted drawing or design (CAD) developed principally on IBM (International Business Machines) Graphics formats and tools 6 Use of DTP applications Used greatly in the fields of marketing, journalism and industrial design, DTP applications fulfil the needs of various professions - from sketches and mock-ups to fashion design - interior design - coachwork (body work) design - web page design -etc. -
