... animator. The most basic computer animation tools assist the process of hand animation by automatically interpolating between the keyframes of images or models. Animation tools have also been developed to composite together multiple layers of an animated scene in much the same way that layers of cels are used in traditional animation. Other more powerful techniques make use of algorithms that render the images from geometric descriptions of the scene. These techniques change the task from drawing sequences of images by hand to using computer tools to effectively specify how images should change over time. In spite of the explosion of 3D computer graphics in film and video, and a plethora of research, many problems remain still open. Most of the animations you see commercially are still done through key framing techniques, which are highly, labor intensive and not necessarily intuitive or enabling of the creative process. ...
