Abstract &   Background	Abstract With the fast development of 3D scanning techniques, 3D models are nowadays intensively used as an emerging type of digital media. Techniques for efficient and robust processing of digital geometry have also become an active area of research in computer graphics. In this paper, several research topics in digital geometry processing field is discussed. These topics almost cover the whole pipeline about modeling, analysis, optimization and applications of digital geometry. The goal is to provide the readers with a comprehensive study of digital geometry processing and hopefully it is helpful to their future research. Keywords computer graphics; digital geometry Background With the development of 3D acquisition techniques, 3D geometric models are more and more widely available. Thus it’s ever demanding to process 3D geometric data in an efficient and reliable way. Research into digital geometry processing has become an active direction in recent years. A variety of algorithms have been proposed, with the potential applications of digital manufacturing, entertainment and cultural heritage protection etc. As a research field with quick evolution, it’s a challenging task to have an overview idea of various aspects of the direction. In this paper, the authors summarize the recent progress in digital geometry processing into a few topics, covering major problems in the digital geometry processing pipeline, namely modeling, analysis, optimization, and applications. The authors hope this work will be beneficial to researchers in the field.
