FIELD: physics.
SUBSTANCE: information about the current position of the terminal is obtained. Determine the area of the virtual screen of the terminal in the corresponding three-dimensional coordinate system of the terminal in accordance with the position information and the radius of the sphere where the central point of the virtual screen area of the terminal is located. The virtual screen area of the terminal is projected onto a pre-installed image that has undergone the curvature process from the start point of the corresponding 3D coordinate system of the terminal and determines the target area projected by the virtual screen area of the terminal in the pre-installed image that has undergone the curvature process. A target area is determined in a pre-established image that has not undergone the curvature process in accordance with the target area in a pre-installed image that has undergone the curving process and selects a target area in the previously installed image that has not passed the curvature process as the current background image of the terminal.
EFFECT: improved image quality when forming a spherical image.
