Embodiment Construction

[0030] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0031] like figure 1 As shown, the XML-based three-dimensional scene dynamic construction method disclosed by the present invention comprises the following steps:

[0032] The basic information of the 3D scene is described by XML coding;

[0033] Use XML coding to describe the attribute information of all solid models in the 3D scene;

[0034] Use XML coding to describe the attribute information of all observation windows in the 3D scene;

[0035] Generate an XML file containing the basic information of the 3D scene, th...

Abstract

The invention discloses an XML-based dynamic construction method and system of a three-dimensional scene. The method includes: using XML code to describe basic information of the three-dimensional scene; using the XML code to describe attribute information of all entity models in the three-dimensional scene; using the XML code to describe attribute information of all observation windows in the three-dimensional scene; and generating an XML file which contains the basic information of the three-dimensional scene, the attribute information of all the entity models in the three-dimensional scene and the attribute information of all the observation windows in the three-dimensional scene. According to the method and system, multidisciplinary virtual-prototype co-simulation and other unified dynamic construction and sharing reuse of three-dimensional scenes of different clients in practical application can be realized.

Description

technical field [0001] The invention relates to the technical field of simulation. More specifically, it relates to an XML-based method and system for dynamically constructing a 3D scene. Background technique [0002] In the process of multidisciplinary virtual prototype collaborative simulation, there are often multiple units and departments to jointly complete the design of a complex product virtual prototype, and personnel distributed in different places need to observe the simulation test of the virtual prototype in the virtual environment on multiple different clients. dynamic behavior. However, the traditional 3D visualization environment is usually built for special applications, which cannot solve the problem of dynamic construction and sharing and reuse across regions and organizations. [0003] XML extensible markup language is a subset of general markup language, due to the extensibility of XML language, it can flexibly add various modules such as new models and...
