Computer Graphics


Published on

Computer graphics are graphics created using computers and the representation of image data by a computer specifically with help from specialized graphic hardware and software.
The interaction and understanding of computers and interpretation of data has been made easier because of computer graphics. Computer graphic development has had a significant impact on many types of media and have revolutionized animation, movies and the video game industry.

Computer Graphics

  1. 1. Prepared & Submitted by… Deepak Kumar Mohapatra
  2. 2. Overview • • • • • • • • • Introduction History Evolution Images Animation Concepts and Principles GPU Applications Conclusion
  3. 3. • The term computer graphics refers to "almost everything on computers that is not text or sound” • Refers to creation, Storage and manipulation of pictures and drawing using a digital computer. • Effective tool for presenting information. • Computer aided design. • Computer aided manufacturing.
  4. 4. What is Computer Graphics? • Creation, Manipulation, and Storage of geometric objects (modelling) and their images (rendering). • Display those images on screens or hardcopy devices • Image processing • Others: GUI, Haptics, Displays (VR) etc
  5. 5. • In 1960, William Fetters a graphic designer for Boeing Aircraft Co. proposed his 3D structure of the human body. This structure was called “Boeing Man”. William Fetters 1928 - 2002
  6. 6. He did so by drawing the 3-D structure of the human body, then scanning them to create images in a 2-D environment such as the computer screen.

  8. 8. In the same year General Electric launched a computer named “TX-2” specially designed for graphic generation. This computer used “Motion Capture” to generate 3-D representation of moving objects like the human body. It also used a lightpen and a scanning pad to draw 3D structures. Motion Capture is the process of recording movement onto a digital model like the TX-2.
  9. 9. Cont... In the early 1980s, the availability of bit-slice and 16bit microprocessors started to revolutionise high resolution computer graphics terminals 3D graphics became more popular in the 1990s in gaming, multimedia and animation. computer graphics have only become more detailed and realistic, due to more powerful graphics hardware and 3D modeling software.

  11. 11. Images In common usage, an image or picture is an artefact, usually two-dimensional, that has a similar appearance to some subject - usually a physical object or a person.
  12. 12. IMAGES
  13. 13. Examples.. Vector Image Pixel Art Image
  14. 14. Computer Animation • Computer animation is the art of creating moving images via the use of computers. • Computer animation is also referred to as CGI (Computer-generated imagery or computergenerated imaging), especially when used in films.
  15. 15. • Images are typically taken by devices such as cameras, mirrors, lenses, telescopes, microscopes, etc. Digital images include both vector images and raster images, but raster images are more commonly used. • The following information should help you get started in the field of computer graphics:  Pixels  Graphics  Rendering  Modeling  Display or Visualization
  16. 16. Morning Evening
  17. 17. • A Graphics Processing Unit or GPU is a dedicated graphics rendering device for a personal computer, workstation, or game console. • It is of two types: a) Integrated b) Dedicated Dedicated GPU Integrated GPU
  18. 18. • Graphics Driver is a collection of application programs for handling tasks related to multimedia, especially game programming and video. For example The Direct X.
  20. 20. There are a variety of uses for computer animation. They can range from fun to practical and educational ones. •Computational physics •Computer-aided design •Computer simulation •Digital art •Education •Graphic design •Infographics •Information visualization •Rational drug design •Scientific visualization •Video Games •Virtual reality •Web design •Computational biology
  21. 21. The world of computer graphics concentrate on reinforcement of performance and the better techniques to bring reality in its output.
