Cross-platform Application Research On Three Dimensional Interactive Courseware

With the development of Internet technology,based on the mobile terminal application of Internet technology has also been rapid development,while the classroom teaching methods and methods have undergone major changes,more and more teachers through the network to high-quality teaching resources efficiently Passed to thousands of students,the basic realization of any person,at any time,anywhere,willing to carry out the goal of learning.At present,these teaching resources are mostly text,picture,audio,video and other traditional multimedia teaching resources,and the traditional teaching resources of the one-way communication,not interactive highlight,the existing video format three-dimensional teaching content needs to install the conversion plug-in,space occupied Large,not conducive to storage and network transmission.The development of new browser technology for the three-dimensional display technology provides the possibility.Newly launched browser HTML5 canvas tags can be rendered based on WebGL 3D content rendering,combined with three.js three-dimensional engine for the presentation of 3D content in the courseware provides a new way,while HTML5 has a cross-platform features Adapting to different mobile terminal applications paved the way.Student information terminal from the traditional desktop to the mobile phone,Pad,from Windows,Android to iOS and other types of terminals can be a very good interactive applications.At the same time based on HTML5 browser applications with more powerful features,more expressive,more clear syntax and other advantages,can be expected in the future there will be more and more three-dimensional teaching content will use HTML5 browser to display.Therefore,the study of HTML5 browser based on the three-dimensional content display technology for the construction of information-based teaching environment has a certain practical significance.This paper studies the three-dimensional content display technology based on HTML5 browser from both theory and application.Firstly,the author introduces the traditional three-dimensional production and interactive display technology,introduces the characteristics of 3D interactive technology based on HTML5,explores the theoretical basis of the technology applied to education and teaching,and expatiates on its unique teaching experience Based on the possibility of its teaching application were analyzed.At the same time,it summarizes the general technical process of the development and production of 3D interactive courseware based on HTML5,and makes a series of cross-platform three-dimensional interactive courseware using the general technical process method of HTML5-based three-dimensional interactive courseware development and production,Finally,the application status and effect of courseware teaching are summarized.In this paper,we try to explore the following aspects: summarize the development process of 3D interactive technology;introduce the process and tools and the key technology of courseware development,and summarize the general technical process of the development and production of 3D interactive courseware based on HTML5 And the application of the HTML5 three-dimensional interactive courseware in teaching is explored and realized through the development example of the molecular three-dimensional structure model,and the application effect is analyzed and evaluated.The paper is divided into six parts:Part 1,the research background,significancePart 2,cross-platform three-dimensional interactive courseware technology overviewPart 3,the theoretical basis of cross-platform three-dimensional interactive coursewarePart 4,based on HTML5 technology,three-dimensional interactive courseware design processPart 5,HTML5 three-dimensional interactive courseware development examplePart 6,Summary and Prospect.
