A, Ismaila W.O Department of Computer Science and Engineering, Ladoke Akintola University of Technology, Ogbomoso, Nigeria *Email: leye_falohun@yahoo.com Abstract Computer graphics is the representation and manipulation of image data by a computer using various technology to create and manipulate images (Shirley et.al., 2005). The development of computer graphics has made computer easier to interact with, and better for understanding and interpreting different types of data. Three-Dimensional (3D) computer graphics represent geometric data that is stored in the computer for the purpose of performing calculations and rendering 2D images which may be for lateral display or for real-time viewing. In this work, 3D computer graphic software is used to produce a model of a real - life assembling of computer devices into a full-blown desktop computer. The work is presented in a video viewing format tat will facilitate independent coupling of systems through a ‘watch-and-fix’ paradigm. Keywords: 2D, 3D, IDE, Assembling, Photo-realistic, Data-visualization, Rasterization. 1. Introduction It is pertinent to discuss Information Communication and Technology development as it serves as a tool in which everyone get updates about everything happening in the environment. Information gets to us through various means which may be text oriented, visual or object- oriented. From observation, people tend to get and understand a message sent out through a visual means than with text or sound, because not everybody can read or hear but everyone can understood and interpret what they see. as a picture speaks more than one million words. Following this observation, there is the need to develop a tool that will give meaning or interpretation to information in form of visual means rather than text. Hence, the need to study and implement events using graphics. This research work attempts to discuss the importance of computer graphics and implement one of its applications relating to computer science and engineering viz-a-viz assembling a personal system unit using computer graphics software firstly by modelling all peripherals to be used and then animating it so that all the peripherals would be brought together to form a complete system unit. 2. Background of Study Computer graphics is the representation and manipulation of image data by a computer using various technologies to create and manipulate images (Shirley et al, 2005). The development of computer graphics has made computer easier to interact with, and better for understanding and interpreting many types of data. Computer graphics is used mostly in the creation of an image that looks like a photograph from a real life, but portrays something that could not actually be taken as a picture. Also it may be desired to create an animation for a movie that portrays an alien creature or creating an architectural rendering to get an idea of what the final building will look like; it is called photo-realistic. The main problem in computer graphics is how to create desired images, time available to create these images, creating a series of image very quickly hopefully 30 per second or more that responds to their inputs; it is referred to as real-time or interactive graphics (Slater et al, 2002). The study of Computer graphics covers a wide range of areas and it is being implemented in data visualization, computer art, entertainment, developing a graphical user interface, virtual reality environment, simulators and graphical display, computer graphics, graphs and charts, computer animation, computer vision, computer modeling, graphics presentation, computer aided design, image processing, manipulation and storage of geometric objects and rendering, converting a scene to an image, shading and illumination of objects, motion capture, medical imaging, photorealistic image synthesis (Yu et. al., 2009). The aforementioned applications can only be achieved when some techniques are mixed and matched. One of the techniques is to begin by attempting to understand the concepts of pixels and how computer represent colors, which is the format for what computer graphics algorithms output. The other is how to represent input data in programs run
