Document Type and Number:
WIPO Patent Application WO/2021/088511
Kind Code:
A1
Abstract:
A method, system, device and medium for describing a relationship between objects in a three-dimensional virtual space, the method comprising: determining whether a node is a first-level node under a three-dimensional virtual space node (702); when it is determined that the node is a first-level node under the three-dimensional virtual space node, determining that the position and rotation direction of an object associated with the node are free (704); when it is determined that the node is not a first-level node under the three-dimensional virtual space node, acquiring the node type of the node and the node type of a parent node of the node (706); and according to the node type of the node and the node type of the parent node, determining whether the object associated with the node maintains or does not maintain a relative position and maintains or does not maintain a relative rotation direction with respect to an object associated with the parent node (708). The method may intuitively describe the relationship between a plurality of objects, edit visualization, reduce understanding costs of a user, and may automatically determine the relative position and relative rotation direction of the plurality of objects, which is convenient for the operation of the user.
