Description

Seminar paper from the year 2018 in the subject Film Science, grade: 1,3, Technical University of Munich, language: English, abstract: Cartoon films nowadays look incredibly realistic, compared to movies produced twenty years ago. To make something that was computer generated look realistic is not an easy task. This short paper discusses how animated movies are rendered and which techniques exist. The general rendering pipeline will be explained and real time rasterization will be compared to the REYES algorithm used in movie production. Ray tracing, its extensions, problems and current solutions will be discussed in detail. Finally, hybrid rendering systems and the performance of rendering systems over the years will be discussed in this state-of-the-art report. The performance of the various rendering techniques is also highlighted and the differences between them are shown.
