Animation
- 1. WELCOME
- 3. INTRODUCTION • Computer animation is the process used for generating animated images by using computer graphics. The more general term computer generated imagery encompasses both static scenes and dynamic images, while computer animation only refers to moving images. • Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film.

- 6. DEVELOPMENTS IN CGI TECHNOLOGIES ARE REPORTED EACH YEAR AT SIGGRAPH, AN ANNUAL CONFERENCE ON COMPUTER GRAPHICS AND INTERACTIVE TECHNIQUES, ATTENDED EACH YEAR BY TENS OF THOUSANDS OF COMPUTER PROFESSIONALS. DEVELOPERS OF COMPUTER GAMES AND 3D VIDEO CARDS STRIVE TO ACHIEVE THE SAME VISUAL QUALITY ON PERSONAL COMPUTERS IN REAL-TIME AS IS POSSIBLE FOR CGI FILMS AND ANIMATION One of the earliest steps in the history of computer animation was the 1973 movie Westworld, a science-fiction film about a society in which robots live and work among humans, though the first use of 3D Wireframe imagery was in its sequel, Futureworld (1976), which featured a computer-generated hand and face created by then University of Utah graduate students Edwin Catmull and Fred Parke.
- 7. • Animation is the rapid display of a sequence of images of 2-D or 3-D artwork or model positions in order to create an illusion of movement. The effect is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in several ways. The most common method of presenting animation is as a motion picture or video program, although there are other methods.
- 8. 2D ANIMATION 2D animation figures are created and/or edited on the computer using 2D bitmap graphics or created and edited using 2D vector graphics. This includes automated computerized versions of traditional animation techniques such as of, interpolated morphing, onion skinning and interpolated rotoscoping.
- 9. 3D COMPUTER GRAPHICS (IN CONTRAST TO 2D COMPUTER GRAPHICS) ARE GRAPHICS THAT USE A THREE-DIMENSIONAL REPRESENTATION OF GEOMETRIC DATA (OFTEN CARTESIAN) THAT IS STORED IN THE COMPUTER FOR THE PURPOSES OF PERFORMING CALCULATIONS AND RENDERING 6D IMAGES. SUCH IMAGES MAY BE STORED FOR VIEWING LATER OR DISPLAYED IN REAL-TIME. 3D ANIMATION
- 10. 3D computer animation combines 3D models of objects and programmed or hand "keyframed" movement. Models are constructed out of geometrical vertices, faces, and edges in a 3D coordinate system. Objects are sculpted much like real clay or plaster, working from general forms to specific details with various sculpting tools.
- 11. Pixar Animation Studios, commonly referred to as simply Pixar (pronounced /ˈpɪksɑr/ and stylized as PIXAR), is an American computer animation film studio based in Emeryville, California. The studio has earned 26 Academy Awards, seven Golden Globes, and three Grammy Awards, among many other awards and acknowledgments.
- 12. Success of Pixar – TOY STORY
- 13. Computer animation can be created with a computer and animation software. Some impressive animation can be achieved even with basic programs; however, the rendering can take a lot of time on an ordinary home computer. Because of this, video game animators tend to use low resolution, low polygon count renders, such that the graphics can be rendered in real time on a home computer.
- 14. FUTURE OF ANIMATION One open challenge in computer animation is a photorealistic animation of humans. The non-photorealistic/cartoonish direction is more like an extension of traditional animation.
