Embodiment Construction

[0023] Below in conjunction with example and accompanying drawing, the present invention will be further described:

[0024] Scalable Vector Graphics SVG (Scalable Vector Graphics) is a graphic format for describing two-dimensional vector graphics based on Extensible Markup Language (XML). SVG is formulated by the Internet Consortium (W3C), and the current mature version is SVG1.1. It is an open standard that can be used to describe static or dynamic vector graphics. In the application field of computer visualization, SVG has unique advantages: (1) SVG is a vector graphics file format standard, and the graphics it represents can be scaled arbitrarily without destroying the clarity and details of graphics; (2) SVG has powerful Drawing ability, use elements such as rectangle, ellipse, line, polyline, polygon and path to describe vector image; (3) SVG is designed based on XML standard, and can establish links with other technologies. Due to the above advantages of SVG, it has a...

Abstract

The invention discloses a method for a virtual experiment apparatus. The method comprises the following steps of: firstly, shooting a photo of the experiment apparatus by using a digital camera, and saving the photo in the format of bmp; secondly, removing the background of the experiment apparatus by using the image background eliminating function of word2010, and saving an obtained image in the format of the bmp; thirdly, performing vectorization on an output image in the previous step by using software Inkscape, and saving an output file in the format of svg; and lastly, opening the output file in the previous step by using a text editor EditPlus, adding functional information (an interface, a display panel and the like) and multi-state information of the experiment apparatus, and saving the file in the format of xml. In the method, file format is XML-based, so that the experiment apparatus described by the file format can be used for various different virtual experiment platforms and has portability.

Description

technical field [0001] The invention relates to a method for a virtual experimental device. Background technique [0002] Virtual experiment is an important application of virtual reality technology in education and training. It refers to various experiments in simulated teaching through computers and network equipment. Virtual experiments can make up for the lack of teaching equipment and are an important means of assisting teaching. The virtual experiment device is the basis of assembling the virtual experiment, and the description and design of the virtual experiment device is the guarantee for the successful implementation of the virtual experiment. [0003] In 1989, Professor William Wolf of the University of Virginia in the United States proposed the concept of virtual experiment, describing a computer-networked virtual experiment environment, with the goal of building a unified information-based and networked environment. Subsequently, various representation methods...
