| Thanks to the prompt development of modern science and technology, profound changes have taken place in 2D animation industry. Sand animation, being one of new 2D manifestations, becomes favored in modern life by its original and characteristic audio and visual effects.Traditional sand animation usually focus on sand painting performance or taking a freeze shoot to reach the effects of sand animation, which have a strict request of sites, lights, and equipments. As a result, sand animation failed to integrates itself to the swift track of modern computer science; render its whole performance cut lackluster, especially in its scene cut.This paper deals with the scene cut of sand animation through application of 2D computer animation technology. Namely, computer-designed sand animation. Aiming to improve traditional sand animation and create a new manifestation of scene cut, this paper puts forward methods and principles of computer-design sand animations in order to meet modern aesthetic needs of 2D animation. |
