...Computer Graphics –B.C.A. (VIth sem ) Viral B. Polishwala Chapter - 6 : Applications of Computer Graphics Computers have become a powerful tool for the rapid and economical production of pictures. There is virtually no area in which graphical displays cannot be used to some advantage, and so it is not surprising to find the use of computer graphics so widespread. Although early applications in engineering and science had to rely on expensive and cumbersome equipment, advances in computer technology have made interactive computer graphics a practical tool. Today, we find computer graphics used routinely in such diverse areas as science, engineering, medicine, business, industry, government, art, entertainment, advertising, education, and training. Figure 1-1 summarizes the many applications of graphics in simulations, education, and graph presentations. Before we get into the details of how to do computer graphics, we first take a short tour through a gallery of graphics applications. 6.1 Presentation Graphics One of the major application areas is presentation graphics, used to produce illustrations for reports or to generate 35-mm slides or transparencies for use with projectors. It is used to produce illustrations for reports or to generate slide for with projections. Examples of presentation graphics are bar charts, line graphs, surface graphs, pie charts and displays showing relationships between parameters. 3-D graphics can provide more attraction to the presentation...

...Computer graphics designer Name University of Maryland University College 08 October 2013 Computer graphics designer Graphic designers create visual concepts, by hand or using computer software, to communicate ideas that inspire, inform, or captivate consumers. They help to make an organization recognizable by selecting color, images, or logo designs that represent a particular idea or identity to be used in advertising and promotions. The digital media and Web technology major is the career that feed my passion, because this career will help me prepare in the field of digital design. I know that this professional field is the correct career for me, because according to the Learning Evaluation and Assessment Directory I took in the EDCP 100 Module Learning Preferences, my best learning style is Tactile, where my strengths have to do with everything that involve engaging physically learning. Therefore, is a fact that I’m a "hands-on learner" which means that I should look for a career where I can use my learning by doing style. I could separate my dreams in two kinds. First will be the dreams that I will like to achieve for my family and second the dreams I will like to achieve professionally work wise. For instances, my family dreams are been able to buy my mother a home and make her life comfortable. I want to be able to provide my wife and children with a good living. I want to be able to provide my children the tools they will need for their education. The...

Essentially, it’s a dot. • The image shown here is the letter S drawn in an area of 20 X 20 square pixels • The more pixels in an image, the smoother the image will appear. Terminology: resolution • Resolution: the number of pixels that can be displayed on a computer monitor. • When the resolution of a monitor is increased, pixels are smaller and closer together, so images appear smaller. • Typical computer monitor and HD television screen resolutions these days are • 720p: means 1366 pixels across by 768 pixels down • 900p: means 1600 pixels across by 900 pixels down • 1080p: means 1920 pixels across by 1080 pixels down All of the above are used in HDTVs and newer LCD displays (computer screens). 2 Resolution: Example of 900p 1600 pixels 900 pixels This screen has a total of 1,440,000 pixels Cartesian Coordinates • In math class, you learned about the Cartesian coordinate system. – Uses X (horizontal) and Y (vertical) axes – (0, 0) is at the center (also called the origin) – An increase in X means moving to the right – An increase in Y means moving up. – The Cartesian coordinate system has both positive and negative...

It discusses the ways in which various forms of information are used and the need for interconnection and networking facilities. ROAD MAP FOR PART ONE Chapter 2 Business Information The requirements for data communications and networking facilities in an organization are driven by the nature and volume of information that is handled. Chapter 2 provides an overview of the four basic categories of information used in any organization: audio, data, image, and video. The chapter discusses some of the salient characteristics of each type and looks at their networking implications. Chapter 3 Distributed Data Processing Chapter 3 describes the nature and role of distributed data processing (DDP) in an organization. Virtually all business information systems organizations are distributed, and the networking and communications requirements are driven by the way in which data and applications are distributed.

Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photography with various...

...CHAPTER 1 INTRODUCTION Even though modern technology has invested millions, even billions, into projection screen technology, high definition projectors, and even projectors for our cell phones, we have forgotten that we will always need something to project on. Unfortunately, with the tragic proliferation of advertising these days, we are probably looking at a future world where all the space on the buildings is taken for billboards and other various projected ads. The only place that would not be taken is the spaces that people walk through. However, that is an option that we can use, with the Heliodisplay or Fogscreen projector. [pic] Figure.1.1 Heliodisplay. Current technologies attempt to create the visual perception of a free-floating image through the manipulation of depth cues generated from two-dimensional data employing well-established techniques. A few examples of these include stereoscopic imaging via shutter or polarized glasses, as well as auto-stereoscopic technologies composed of lenticular screens directing light from a conventional display, or real-imaging devices utilizing concave mirror arrangements. All of these technologies suffer convergence and accommodation limitations. In order to resolve this visual limitation, the image and its perceived location must coincide spatially. A well-established method solving this constraint is by projection onto an invisible...

...How virtual reality work Virtual reality is a 3-dimensional, computer-generated graphic representation of objects or scenes with the aim of giving the viewer an illusionary sense that such objects or scenes exist in reality. Virtual reality has been designed to address one or more of our senses--visual (sight), auditory (hearing), tactile (feel) and olfactory (smell). As of now, computer and electronic scientists and engineers are working on a system that will include the sense of taste. For virtual reality to work, there are three imperatives--a computer, special software and the individual user. There are various input devices to greatly enhance the virtual reality experience and make it work--items such as helmets, glasses, joysticks, mice and wands. These input devices are designed to record and measure electronic signals and convert them into a physical world. In this video, the author-Oliver Kreylos wanted to explain the ways on how our sight respond can generate the change in virtual reality image. This video is divided into four parts, namely: 3D vision, Stereoscopic display, Head tracking and HMD vs CAVE and the author will explain individually how different technique work together with picture. Part I- 3D Vision Humans have two eyes located side-by-side in the front of their head, each eye captures its own view and the two separate images are sent on to the brain for processing. When the two images arrive simultaneously in the back of the brain, they...

...Reality Gets Better Unit 4 IP Christina Connell MGMT305-1104-01 AIU Online Reality Gets Better What is the difference between virtual reality and augmented reality? Virtual reality computer programs are designed to simulate real life. The user wears special clothing and head gear that allows them to be completely immersed in the program. The clothing helps them to navigate through the system because it takes the body movements of the user and communicated that to the computer. For example, if you are taking a virtual tour of a house and you want to walk to the next room your feet moving communicate to the computer the direction to take you. Augmented reality is technology that allows the user to enhance visualization of reality. It takes real life images and enhances them with graphics to give the user a different perspective of reality. A great example of this is used in the medical field. During surgery they can use augmented reality software to superimpose ultrasound images on the patient to help the surgeon know where the problem is. Of course it is used in our everyday or at least every weekend life when we watch sports and they show those lines on the field showing where the first down goal is (Laudon, 2010). Why is augmented reality so appealing to marketers? Marketing is a business that is all about appealing to the customer. How do you get the attention of the consumer? You have the flashier ads and the attention getting signs. How about...

...DVD player or computer. Film trailers could be added on to DVD format and burned onto disks but isn’t really popular as it wouldn’t really be needed. User generated content can be transferred onto DVD, CDs or ROM an example would be remixes of music can be burned onto a CD and can be copied numerous times to sell that CD or just give it out to friends to listen to and see what they think. You can pretty much transfer anything onto a CD, DVD or RAM. Only audio files can be burned or opened on a CD but on DVDs audio and video can be added. Games can be transferred on to discs then inserted into a gaming PC or gaming console to be played by the user, these are very popular in this generation as gaming has advanced and improved in so many ways in recent years. Education learning purposes are used on DVDs and CDs for example a child learning basic skills would be able to do so simply by watching a DVD and allowing them to learning in a more fun way than rather reading a book or being told by another person. Presentations Short films can be added on presentations to make presentations more interesting rather than just simply showing a whole load of text boxes, short videos will be able to explain better to students or audience rather than reading it out to them. E learning is used on presentations as a presentation can be just a slideshow explain the background of a topic or teaching the audience on how to complete a task for example a slideshow explaining how a computer sends signals...
