Fractal geometry has become popular in the last 15 years,its applications can be found in technology, science, oreven arts. Fractal methods and formalism are seen today as ageneral, abstract, but nevertheless practical instrument forthe description of nature in a wide sense. But it wasComputer Graphics which made possible the increasingpopularity of fractals several years ago, and long aftertheir mathematical formulation. The two disciplines aretightly linked.The book contains the scientificcontributions presentedin an international workshop in the "Computer GraphicsCenter" in Darmstadt, Germany. Thetarget of the workshop was to present the wide spectrumof interrelationships and interactions between FractalGeometry and Computer Graphics. The topics vary fromfundamentals and new theoretical results to variousapplications and systems development. All contributions areoriginal, unpublished papers.The presentations have beendiscussed in two working groups; the discussion results,together with actual trends and topics of future research,are reported in the last section.The topics of the book are divides into four sections:Fundamentals, Computer Graphics and Optical Simulation,Simulation of Natural Phenomena, Image Processing and ImageAnalysis.

Turbulente gasf|rmige Ph{nomene wie Wolken, Rauch, Dunst, Flammen etc. werden ben|tigt, um den Realit{tseindruck rechnergenerierter Bilder von Au~enszenen zu erh|hen. Solche Effekte werden sowohl im Bereich der optischen Simulation (Flug- und Fahrsimulatoren) als auch als Spezialeffektef}r rechnergenerierte Animation ben|tigt. Die Schwierigkeit dabei ist einerseits, da~ solche gasf|rmigen Objekte recht komplex sind, andererseits,da~ sie einer Dynamik in Form einer turbulenten Ver{nderung ihrer Form mit der Zeit unterliegen. In diesem Buch werden alle wichtigen existierendenVerfahren zur Generierung solcher Effekte evaluiert und mit vollkommen neuenAlgorithmen erweitert und erg{nzt. Als Basis der Modellierung dienen geeignet parametrisierte fraktale Strukturen; um dynamische turbulente Bewegung zu imitieren, werden zeitvariante Fraktale eingef}hrt. Die Visualisierung von Volumendaten wird ebenfalls detailliert erl{utert. Sowohldie Theorie als auch die Algorithmen werden mit Hilfe zahlreicher Abbildungen ausf}hrlich evaluiert und diskutiert.Das Buch wendet sich prim{r an computergraphikorientierte Berufe (Computeranimateur, Ingenieur, Software-Entwickler, Sumulationstechniker), die solche Effekte modellieren und visualisieren wollen oder sich mit der Visualisierung von Volumendaten, z.B. im Bereich der Medizin oder Ingenieurwissenschaften, besch{ftigen. Die detaillierte Behandlung des Stoffes, der systematische und anschauliche Aufbau des Buches sowie die zahlreichen Abbildungen machen es auch f}r den Studenten, Hobby-Programmierer und interessierten Laien attraktiv.

This book constitutes the thoroughly refereed post-conference proceedings of the Third International Workshop on Computational and Clinical Applications in Abdominal Imaging, held in conjunction with MICCAI 2011, in Toronto, Canada, on September 18, 2011. The 33 revised full papers presented were carefully reviewed and selected from 40 submissions. The papers are organized in topical sections on virtual colonoscopy and CAD, abdominal intervention, and computational abdominal anatomy.

This book contains the final versions of the proceedings of the fifth EUROGRA­ PHICS Workshop on Rendering held in Darmstadt, Germany, between 13-15 June 1994. With around 80 participants and 30 papers, the event continued the successful tradition of the previous ones establishing the event as the most im­ portant meeting for persons working on this area world-wide. After more than 20 years of research, rendering remains an partially unsolved, interesting, and challenging topic. This year 71 (!) papers have been submitted from Europe, North America, and Asia. The average quality in terms of technical merit was impressive, showing that substantial work is achieved on this topic from several groups around the world. In general we all gained the impression that in the mean time the technical quality of the contributions is comparable to that of a specialised high-end, full­ scale conference. All papers have been reviewed from at least three members of the program committee. In addition, several colleagues helped us in managing the reviewing process in time either by supporting additional reviews, or by assisting the members of the committee. We have been very happy to welcome eminent invited speakers. Holly Rush­ meier is internationally well known for her excellent work in all areas of rendering and gave us a review of modelling and rendering participating media with em­ phasis on scientific visualization. In addition, Peter Shirley presented a survey about future rends in rendering techniques.
