-With the development of science and technology, virtual reality technology as a new technology has been applied to more and more areas. In the traditional shipbuilding industry, the shipbuilding period is usually long and frontline workers tend to make mistakes because of negligence of small details while making ship fitting according to the two -dimensional drawing of the ocean designer. In this study, virtual reality technology is applied to build a three -dimensional solid model in order to realize a vivid expression of the ship model and its assembly process. Compared with the traditional abstract drawing, the three-dimensional solid model allows designers and shipbuilders to be more unified, avoids wasting of resources in the construction process and makes it more convenient for the frontline workers to operate in reality, so as to improve the shipbuilding efficiency and shorten the shipbuilding cycle.
