Visual effects that allow a new dimension to display different objects, are increasingly appearing in daily life. Their appearance is caused by the rapid development of technical sciences and computer graphics. The frequently asked question is how do they achieve these visual effects, 3D animation and virtual reality. All of these are products of computer graphics and animation, visual areas of computer science that is developing at a breathtaking speed, and are used in engineering, science, medicine, arts, and military applications. Nowdays 3D animation has overcome method of classical animation because of growing presence of computer technology, but principles of classical animation are not completely ignored. In computer animation, the best results are achieved by the authors and animators trained by principles of classical animation, because they know the technical principles that can be applied to any configuration form. Precise knowledge of the classical techniques today is more important than ever, especially in the phase of the project because the computer animation allows far more improvisation than classical. Basic principles of traditional animation defined by the Walt Disney Studios before nearly 80 years are now also used in 3D animation. Theoretical part of this thesis describes 12 principles of Disney animation, application of these principles in a 3D environment and their implementation. Besides, certain sections describes the rules for modeling 3D model suitable for animation and the process of animation, which also constitutes the basis for practical part of this thesis. The practical part shows a stylized human figure which performs certain actions in accordance with the basic principles of animation.
