Photorealistic Rendering Techniques

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.

It contains 28 selected international contributions presented at the Fifth Eurographics Workshop on Rendering, held in Darmstadt, Germany, in June 1994. After more than 20 years of development, rendering of realistic images remains an interesting and challenging field. The book covers a wide spectrum of topics including not only the "classics" such as radiosity, ray tracing, meshing and sampling, and Monte Carlo and viewing solutions, but also new areas of increasing interest, such as participating media, dynamic solutions and walkthroughs, and wavelets
