Research On The Design Of 3D Resources In Classroom Teaching

In recent years, the information that students come into contact with is more diversified, and the field of their vision is more and more wide. In the traditional classroom teaching, the students’ learning interest is decreased, they can’t concentrate their attention on the teaching resources, and don’t like to participate in teaching interaction activities. A variety of bad mood not only make students learning efficiency decline, but also not conducive to their physical and mental health development. How to attract students’attention to the content of classroom teaching, to promote their active learning is an urgent problem to be solved.3D teaching resources can give students a more comprehensive, more realistic visual senses both from the sense of color and space, it can close the distance to the eyes, activate a static object and show an object repeatedly. They have stronger interaction and performance effects, through interactive presentations and motion simulation in the three-dimensional space, they can make up the visual angle and space experience that the traditional media can’t present. More and more scholars approve the application of three-dimensional resources in classroom teaching, is a good choice, whether from the point of demonstrating knowledge, or from the point of making students learning more initiatively, and a large number of three-dimensional resources are applied in teaching. However, the research on 3D teaching resources has certain limitations, the research is focused in virtual reality technology, holographic projection technology,3D display technology and 3D printing technology, inadequate for the study of 3D technology to visual expression, development and support tools and due to cost constraints,3D resource is not only limited in form, but also has obvious deficiency in quantity. In this paper, the key issues of 3D teaching resources, the visual expression of 3D resources and the design and production of 3D resources are studied, we present 3D teaching resources based on production and display, build up the 3D classroom resource application system, which includes the resources from the prophase preparation to the post production, the synthesis output and the demonstration.In order to make the acquisition of 3D data more elaborate and realistic, improve the acquisition speed, in addition to the traditional resource library data acquisition method, this paper presents the data acquisition method based on 3D software and 3D scanner. As the existing 3D data visualization is in the form of a single method, based primarily on equipment, we present a 3D data visualization method based on OSG platform, in addition to the common 3D printing visualization method. In the VS2010 environment, not only can we show the established model, but also can modify and establish of interactive features through code editor. Because 3D resources are based on the visualization of computer technology, it has the characteristics of digital resources:portability, non distortion and real time sharing, meanwhile it has enriched the form of 3D data visualization.In order to make a personal learning interactive 3D teaching resources which accord with the students’ cognitive habits and the characteristics of the subject of production, this article embarks from the actual case, gives the design steps and methods of 3D interactive simulation case. This paper describes the design theme, learners and knowledge point analysis, script production, animation, interactive design, subtitles and sound design, etc.in detail, mainly from the preparation, production, processing and synthesizing outputs three major aspects, the final resource output format is.Exe. Teachers and students only need a computer for teaching and learning, and students can have real-time interaction with teaching resources according to their own learning needs as the main control of showing the resources content and speed.
