Computer Animation

Nadia Magnenat Thalmann, Daniel Thalmann · 1998

Introduction The main goal of computer animation is to synthesize the desired motion effect which is a mixing of natural phenomena, perception and imagination. The animator designs the object's dynamic behavior with his mental representation of causality. He/she imagines how it moves, gets out of shape or reacts when it is pushed, pressed, pulled, or twisted. So, the animation system has to provide the user with motion control tools able to translate his/her wishes from his/her own language. Computer animation methods may also help to understand physical laws by adding motion control to data in order to show their evolution over time. Visualization has become an important way of validating new models created by scientists. When the model evolves over time, computer simulation is generally used to obtain the evolution of time, and computer animation is a natural way of visualizing the results obtained from the simulation. To produce a computer animation sequence, the animator ha

Animation is the production of consecutive images, which, when displayed, convey a feeling of motion. An-imated images are almost magical in their ability to capture our imagination. By telling a compelling story, astounding with special e ects, or mesmerizing with abstract motion, animation can infuse a sequence of inert images with the illusion of motion and life. Creating this illusion, either by hand or with the assistance of com-puter software, is not easy. Each individual image, or frame, in the animated sequence must blend seamlessly with the other images to create smooth and continuous motion that ows through time. Traditionally, animation was created by drawing images of the characters for each frame in the action. At the start of the production, the animator is given storyboards, which are sketches depicting the sequence of major actions and illustrating the expressions of the characters. The animator also works from a nished soundtrack, which determines the timing of the piece. In older animations, the background scenery was often stationary and the characters were painted on cels, pieces of clear celluloid that could be stacked on top of the background. Most hand animation is created with keyframing where a lead animator creates the key, or most important frames, and a second animator creates the in between frames. Regardless of the medium, the challenge for the animator is to create images that impart expressiveness and life to the character. The most basic computer animation tools assist the process of traditional animation by automatically gener-

A wide variety of techniques are used in the process of creating a complex computer animation such as DisTo appear in the Encyclopedia of Computer Science, from International Thomson Computer Press, Fourth Edition. ney and Pixar's Toy Story (www.toystory.com). These techniques can be grouped into two main classes: two dimensional (2D) and three dimensional (3D). Although there is some overlap between the two classes, 2D techniques tend to focus on image manipulation while 3D techniques usually build virtual worlds in which characters and objects move and interact. 1 Two-dimensional Animation The impact of 2D techniques can be as spectacular as the addition of the film character ET to a shot of the moon or as su

Computer animation may be defined as a technique in which the illusion of movement is created by displaying on a screen or recording on a device a series of individual states of a dynamic scene. The key issue of computer animation is defining motion, commonly known as motion control methods (MCMs). MCMs may be classified according to the nature of the information that is directly manipulated: geometric, physical, or behavioral
