At approaches to image-based rendering, and subsequently present we also require the scene to have a static back- many new rendering techniques and representations have ground, while the dynamic part of the scene is smaller than been proposed based on them. Nevertheless the main limi- the rest. The extension of static light fields to dynamic tation remains that in almost all of them only static scenes scenes and objects gives rise to several problems: are considered. In this contribution we describe a method for calibrating a scene which includes moving or deforming
