What is Virtual Reality in Computer Graphics?
/ April 11, 2018

Virtual Reality is a major asset and aspect of our future. It is the key to experiencing, feeling and touching the past, present and the future. It is the medium of creating our own world, our own customized reality. Modeling is used to build structures that serve as proxies for other objects. Virtual reality is more than just interacting with 3D worlds. By offering presence simulation to users as an interface metaphor, it allows operators to perform tasks on remote real worlds, computer generated worlds or any combination of both. The simulated world does not necessarily have to obey natural laws of behavior. Such a statement makes nearly every area of human activity a candidate for a virtual reality application. However, we can identify some application areas were benefits are more straightforward than others. Overview of Virtual Reality A virtual reality system is essentially an interactive simulation that can represent a real or abstract system. Virtual Reality (VR) is the use of computer graphics and other technologies to create a simulated environment in which the user interacts.  While computer graphics supplies the visual component of the experience via a normal screen, a stereoscopic display, or head‐mounted technology; a variety of other devices…

What is Multimedia Database in Computer Graphics?
/ April 10, 2018

The exponential growth of the technological advancements has resulted in high-resolution devices, such as digital cameras, scanners, monitors, and printers, which enable the capturing and displaying of multimedia data in high-density storage devices. Furthermore, more and more applications need to live with multimedia data. However, the gap between the characteristics of various media types and the application requirements has created the need to develop advanced techniques for multimedia data management and the extraction of relevant information from multimedia databases. At the heart of multimedia information systems lies the multimedia database management system. Everyone deals with multimedia at every walk of lives. We work with multimedia and are surrounded by multimedia. Due to the advancement of modern computer and information technology, multimedia systems play more and more impact on our lives. Overview of Multimedia Database Multimedia database is a kind of database like any other databases containing multimedia collections. Multimedia is defined as the combination of more than one media, they may be of two types–static and dynamic media. Text, graphics, and images are categorized as static media; on the other hand, objects like- animation, music, audio, speech, video are categorized as dynamic media. Graphic images may consist of cliparts, photographs,…
