Introduction Computer Graphics (CG) is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. Computer Graphics is the pictorial representation and manipulation of data by a computer. Applications of Computer Graphics Data Visualization – Charts and Graphs Computer Aided Design (CAD)-Now a days used in different sectors Virtual Reality o VR: User interacts and views with a 3D world using “more natural” means o Best VR Data Visualization o Scientific, Engineering, Medical data o Visualizing millions to billions of data points o Different schemes Education and Training o Models of physical, financial, social systems o Comprehension of complex systems Computer Art o Fine and commercial art o Performance Art o Aesthetic Computing o SIGGRAPH (Special Interest Group on Graphics and Interactive Techniques) Games/Movies Image Processing o Manipulating images using efficient algorithm.

Page 2 of 4 Computer graphics in CAD A major use of computer graphics is in design processes, particularly for engineering and architectural systems. For some design applications; objects are first displayed in a wireframe outline form that shows the overall sham and internal features of objects. Software packages for CAD applications typically provide the designer with a multi window environment. Each window can show enlarged sections or different views of objects. Standard shapes for electrical, electronic, and logic circuits are often supplied by the design package.
