FAQs:

Q1: What are computer graphics?

A1: The process of creation of pictures with the help of a computer is known as Computer Graphics. The end product of the computer graphics is a picture. This could be a business graph, drawing, and engineering sheets. To create and manipulate pictures on a display device is the use of computers . It comprises of different software techniques to create, store, modify, represents pictures.

Q2: What is the difference between 2-D and 3-D graphics?

A2:

 2D Graphic system 3D Graphic system Usage of only two coordinates X and Y Usage of three coordinates X, Y and Z Techniques and their application are fundamental to mechanical drawings, electrical engineering projects, clothing construction and architecture Techniques and their application are fundamental to the entertainment, games, and computer-aided design industries

Q3: What are the application of Computer graphics ?

A3:

1. For engineering and architectural systems etc, Computer-Aided Design is required.
2. Presentation Graphics
3. Computer Art
4. Entertainment
5. Education and Training
6. Visualization
7. Image Processing
8. Graphical User Interface
Q4: What are the different methods of 3D object representations?

A4:

1. Polygon and Quadric surfaces: For simple Euclidean objects
2. Spline surfaces and construction: For curved surfaces
3. Procedural methods: Eg. Fractals, Particle systems
4. Physically based modeling methods
5. Octree Encoding
6. Isosurface displays, Volume rendering, etc.
Q5: What is the scope under Computer graphics?
A5: Advertisement industry, Print Industry, Web designing industry etc need Graphic designers. Photoshop, Gimp, Flash, Dreamweaver, Fireworks, Blend or more applications need to be studied by new designers.
• For the visual style and images in magazines, newspapers, product packaging, and movie and television productions, Art directors are responsible.
• Handmade objects, such as pottery, glassware, textiles, and other objects that are designed to be functional create art for sale and exhibition by Craft and fine artists by using a variety of materials and techniques.
• To design page layouts for newspapers, books, brochures, and other items which printed or published online, desktop publishers use computer software.
• To convert the designs of engineers and architects into technical drawings, drafters use software .
• The concepts for manufactured products, such as cars, home appliances, and toys are developed by Industrial designers.
• Animation and visual effects for television, movies, video games, and other forms of media are created by Multimedia artists and animators.
• To communicate complex and technical information more easily, technical writers prepare instruction manuals, how-to guides, journal articles, and other supporting documents.
• Websites are created and designed by Web developers.
