A survey of the virtual rebuilding of manufacturing process based on virtual and reality technologies

Traditional patterns of manufacturing training have a lot of problems, such as high cost, low efficiency and so on. Simulative training for producers based on virtual reality and human-computer interaction, is one of the most economical methods at present. This paper proposes the virtual rebuilding of manufacturing process based on virtual and reality technologies, analyses its status quo at home and abroad, and introduces its key technologies and algorithms, including the simulation object modeling, virtual scene production, human-computer interaction, production process simulation and the simulation result assessment. At last, it makes the summary and looks forward to the future.
