Philip Dutr´e(2008)AbstractThe photo-realistic modeling and animation of complex scenes in 3D re-quires a lot of work and skill of artists even with modern acquisition tech-niques. This is especially true if the rendering should additionally be per-formed in real-time. In this thesis we follow another direction in com-puter graphics to generate photo-realistic results based on recorded videosequencesofoneormultiplecameras.
