Accelerated rendering method based on area division

In recent years, computer technologies such as graphics, network technology, and virtual reality are increasingly used in the field of cultural relics protection and cultural communication. Smart handheld terminals are also widely used in the display of special artifacts because of their convenience. The existing hand-held terminals can not catch up with ordinary computers in terms of high-performance computing and efficient three-dimensional rendering. For the rendering of large-scale scenes and models, it is difficult to complete on current handheld terminals. In order to solve this problem, the accelerated rendering method based on region division proposed in this paper utilizes the characteristics of the rendering scene to perform some pre-processing and actual rendering before reducing the amount of calculation according to the preprocessing results. It uses the artifacts. Protect the intrinsic characteristics of large scenes in the field, divide the area, and quickly perform large scene rendering. This paper first analyzes some of the characteristics inherent in the large scenes of cultural relics protection. According to the characteristics, it proposes a region-based patch reduction method to reduce the amount of rendering calculations. Finally, this method was experimentally analyzed.
