This paper introduces a novel method to automatically generate camera animation for scenes with objects in motion. A means of bounding the scene is first discussed, in order to provide a restricted surface for the camera to move along. Methods for generating static views of a scene are then developed, based on prior literature in the field of optimal camera views. Methods for producing smooth animations for camera paths are developed. This is broken up into two constraints; the minimum distance constraint and the minimum angle constraint. Finally, a camera path is produced based on the two prior constraints. This framework is then applied to the problem of facial tracking and visualizing a large scene.
