Problems solved by technology

However, the current object space positioning method in this 3D virtual reality scene needs to be adjusted separately on multiple 2D views to realize the object space positioning. For designers, the operation is very inconvenient and wastes design time.

Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0023] The invention provides a method for arranging objects in space in a three-dimensional virtual reality scene. The method obtains the drive data generated by controlling the objects in the three-dimensional virtual reality scene by acquiring an external device that can obtain three axial drive data, and then converts the three-dimensional virtual reality scene. The drive data is converted into motion offsets, including movement offsets and rotation offsets of objects, so that the spatially accurate positioning of objects in a 3D virtual reality scene can be accomplished only in a 3D view. see figure 2 , the specific steps of this method are:

[0024] 21. Obtain the drive data generated by the external d...

Abstract

The invention discloses an object space positioning method and device in a three-dimensional virtual reality scene. According to the object space positioning method, an external device capable of obtaining three pieces of axial drive data can be used for moving objects in the three-dimensional virtual reality scene to obtain motion offset (including movement offset and rotation offset) of the objects, and thus the exact space placing position of the objects in the three-dimensional virtual reality scene can be finished only in a three-dimensional view, and other views only taken as visual reference objects are placed on operation positions; and therefore, the design time of designers of the three-dimensional virtual reality scene is shortened, and the work load is reduced.

Description

technical field [0001] The invention relates to the field of virtual reality applications, in particular to a method and device for arranging objects in space in a three-dimensional virtual reality scene. Background technique [0002] The rapid development of computer image technology has made great progress in 3D virtual reality technology. The difference between 2D and 3D space operations, see figure 1 , in two-dimensional space, we have two coordinate axes (X, Y), we call it a plane. The three-dimensional space is what we call the three-dimensional space. If we want to determine the position of an object in these two spaces, we only need to specify the coordinate values ​​of each axis of the object. However, if this process is implemented on a computer in the form of computer graphics, the result may not be so simple. For two-dimensional space, because the display we use is also two-dimensional, we only need to map our two-dimensional space to the computer display. We...
