Conventional Animation,Animation can be defined in different ways. For John Halas [1968], one of the world’s most famous animators, “movement is the essence of animation.” A similar approach defines animation as “art in movement.” Some more precise definitions are given below:

诱使

Computer Animation,Although computer plays an ever-increasing role in animation, the term “computer animation” is imprecise and can sometimes be misleading. This is because the computer can play a variety of different roles:

Keyframe and Painting Systems,We showed in Chap. 3 that numerous steps in conventional animation can be assisted or improved by computer. In particular, the computer can be used:.These different aspects will be studied in detail.

向下

Motion Control in 3D Animation,Most authors [Magnenat-Thalmann and Thalmann 1985b] distinguish between two types of three-dimensional computer animation: keyframe animation and algorithmic animation.

Human Modeling and Animation,As stated by Norman Badler [1982], one of the best-known specialists in this area, modeling realistic human forms remains one of the most difficult and challenging problems.

Object-oriented and Actor Languages and Systems,As indicated in Chap. 6, modeled computer animation involves three main activities:

Hidden Surfaces, Reflectance, and Shading,mputer-generated image, lines which could not really be seen by an observer first must be removed. This process has been a common research theme since the first three-dimensional systems; numerous algorithms have been proposed to solve the problem [Sutherland et al. 1974].
