High-quality 3D scenes often show poor rendering effect and insufficient operational performance in low-end devices. Therefore, how to make better use of 360-degree panoramic technology and replace the traditional pure model scene by visual deception is of great significance to the picture quality improvement and performance optimization of low-end equipment. In this paper, a three-degree-of-freedom (3-DOF) application scenario for indoor simulation is used as an example. Under the premise of 360-degree panoramic technology, depth information is obtained through laser ranging, converted into a two-dimensional form of depth image with the help of spherical coordinates, and combined with a transparent information image, the depth image is compressed using DEFLATE compression algorithm, and finally be stored. By optimizing the data through bilinear sampling and with the help of geometric knowledge, the occluded parts are removed or translucent according to the actual situation when the graphics are rendered, and the occlusion relationship is correctly handled in order to achieve a real integration of the virtual environment with the 3D objects. Through multiple data, it is shown that the method possesses significant performance improvement while ensuring geometric realism.
