Problems solved by technology

[0007] In the existing patented technologies and documents, there is no correlation between scene graphs and user access in other patent documents on scene graphs or scene management, and there is also a lack of effective scene management methods for distributed scene graphs. Processing method, there are problems such as low scene rendering efficiency

Embodiment Construction

[0093] The present invention will be further described below through the embodiments in conjunction with the accompanying drawings.

[0094] The method of the present invention passes through figure 1 The example system implementation shown.

[0095] Such as figure 1 As shown, the user interface of the system in this embodiment includes three parts, the user authority UI, the scene node UI, and the scene object UI, which are respectively used to display and edit the user's authority to the scene, the logical relationship of the scene node, and the scene in the scene object. The scene manager maintains the scene graph information visible to the client user, the hierarchical tree list of scene nodes, and the list of different types of scene objects; The display and editing of the pointed scene objects; the scene manager provides the drawing module with a list of different types of scene objects for displaying the scene. At the same time, the user authority maintenance module...

Abstract

The invention discloses a method for constructing multi-scene graphs in a distributed virtual environment. This method is: 1) divide the scene graph in the scene graph server into public scene graph and private scene graph; Permission to operate the private scene graph, edit the editable private scene graph or create a sub-scene graph and save it to the scene graph server as the user's private scene graph; wherein, each scene graph corresponds to a A set of scene objects. Scene objects describe various static or dynamic entity objects in the virtual reality environment except terrain scenes. Each scene object corresponds to a scene node in the scene graph. According to the logic between scene objects Relationships determine the logical relationship between scene nodes; each scene graph has a root node representing the scene graph. The invention improves the drawing efficiency of the scene.

Description

technical field [0001] The invention relates to a method for constructing a multi-scene graph in a distributed virtual environment, belonging to the fields of virtual reality and graphics. Background technique [0002] In applications related to virtual reality, in addition to terrain scenes composed of DEM and images in the virtual environment, 3D architectural models and other scene object models generated by external loading, editing tools in the virtual environment, or by means of scene semantic annotation , are an indispensable and important part of virtual scenes. These scene objects include not only static 3D architectural models, but also various dynamic models such as cars, as well as various ideographic primitive models such as icons or information labels. For the whole process of describing the development and changes of virtual environment events until the end, the whole process management of the position and state of scene objects in virtual scene becomes an imp...
