Abstract

The invention discloses a roaming synchronous display method and device for a three-dimensional scene. The roaming synchronous display method and device for the three-dimensional scene can effectively carry out synchronous display on the three-dimensional scene in the roaming process of the three-dimensional scene. The method comprises the steps of carrying out control over the three-dimensional scene according to control data after receiving the control data from a control terminal, detecting the state changing conditions of the three-dimensional scene based on preset time intervals, obtaining the current state of the three-dimensional scene when the three-dimensional scene is detected to be in a changing state, and then displaying the current state changing process of the three-dimensional scene. According to the method, the state changing conditions of the three-dimensional scene are detected in real time, and the current state of the three-dimensional scene is obtained when the three-dimensional scene is detected to be in the changing state; the current state changing process of the three-dimensional scene is then displayed, so that the data size processed by a display unit at each time interval is reduced, the synchronous display is effectively carried out on the changing process of the three-dimensional scene, and the problem of tearing of pictures is solved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a method and device for synchronously displaying three-dimensional scene roaming. Background technique [0002] The 3D scene is to create a virtual information environment on the multi-dimensional information space, simulating an interactive and illusory space scene. [0003] The 3D scene roaming is a virtual roaming realized in the 3D scene. In recent years, with the continuous development of visualization technology, 3D virtual roaming has been widely used, such as games, flight training, military exercise simulation, etc. [0004] The 3D scene roams in the video wall system. After receiving the control data from the control terminal, the display unit controls the 3D scene according to the control data, and then displays the changing state of the 3D scene. Due to the different scene complexity of each display unit of the video wall, the images displayed...
