3D Visualization In Computer Graphics

Abstract :

In the last several years, three-dimensional computer graphics has become a critical technology in the PC world. 3D graphics capability is a prerequisite for two major markets: Computer-aided industrial and mechanical design (for which the majority of workstations and high-end PCs are sold today) and entertainment (especially computer games, which are driving significant new PC hardware and software purchases by consumers).

Abstract:
3D computer graphics (in contrast to 2D computer graphics) use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing, here we explain The process of creating 3D computer graphics and it can be sequentially divided into three basic phases: 3D modeling which describes the process of forming the shape of an object, layout and animation which describes the moti ....etc

Definition
Affordable bandwidth will be as essential to the Information Revolution in the21 st century as inexpensive power was to the Industrial Revolution in the 18 th and 19 th centuries. Today's global communications infrastructures of landlines, cellular towers, and satellites are inadequately equipped to support the increasing worldwide demand for faster, better, and less expensive service. At a time when conventional ground and satellite systems are facing increasing obstacles and spiraling costs, a low cost solution is being advocated. ....etc

INTRODUCTION

There are various applications that require a 3D world to be simulated as realistically as possible on a computer screen. These include 3D animations in games, movies and other real world simulations. It takes a lot of computing power to represent a 3D world due to the great amount of information that must be used to generate a realistic 3D world and the complex mathematical operations that must be used to project this 3D world onto a computer screen. In this situation, the processing time and bandwidth are at a ....etc

WireGL A Scalable Graphics Subsystem for Clusters
Abstract
WireGL is a framework for scalable interactive rendering on a cluster of workstations. WireGL provides the OpenGL API to each node in a cluster, virtualizing multiple graphics accelera- tors into a sort-_rst parallel renderer with a parallel interface. Using exible display manage- ment, WireGL can drive a variety of output devices, from standalone displays to tiled disp ....etc

ABSTRACT
A Graphics Processing Unit (GPU) is a microprocessor that has been designed specifically for the processing of 3D graphics. The processor is built with integrated transform, lighting, triangle setup/clipping, and rendering engines, capable of handling millions of math-intensive processes per second. GPUs allow products such as desktop PCs, portable computers, and game consoles to process real-time 3D graphics that only a few years ago were only available on high-end workstations. Used primarily for 3-D applications, ....etc

Abstract: Watermarking techniques are primarily used for copyright protection. A simple and robust watermark-like digital authentication scheme is proposed. This work has two major merits. First, the watermark used in the proposed authentication scheme is the same type used in the original image, e.g. grey level images. Second the proposed scheme meets the requirements for watermarking techniques. lllegal users cannot perceive and break the watermark signed from the original image. Furthermore, the signed watermark is robust ....etc

Abstract”
Creating a 3D Graphics Rendering Engine is not a trivial task as users often demand for high quality output and performance. With the development of computer graphics hardware, graphics engine is a research focus. In this paper, an object-oriented 3D graphics engine”Gingko is presented and implemented. We discussed the general architecture of this engine and the relationships of every module. Not only does this engine support extendable software architecture, but also it provides high efficient scene ren ....etc
