Abstract
As an outcome of the further development of modern simulation technology, virtual technology has been widely used under the support of computer technology and multimedia technology and provides more interactivity and perceptibility. However, in the past, the design of virtual teaching system was mainly based on theoretical analysis, resulting in low practicability. The appearance of WebGL standard simplifies the procedure of developing web-specific rendering plug-ins, contributing to more seamless 3D scenes and models. This study constructed the theory from several aspects including multimedia teaching effect under cognitive theory, WebGL architecture, design of virtual teaching curriculum based on WebGL, and built a WebGL-based virtual teaching platform for mole design through designing the overall framework and constructing the three-dimensional teaching environment. Practice has proved that the platform makes it convenient for users to create teaching scenarios and engage in interactions, and strengthens students’ understanding of theoretical knowledge and skill practice.
Highlights
Virtual technology as a new type technology based on multiple computer technologies and multimedia technology can simulate and virtualize the real world or objects so as to satisfy people’s demands by adjusting self-variation according to surrounding environment changes
Virtual teaching course based on WebGL in this design is obviously different with traditional teaching mode and previous virtual teaching systems
Based on completing theoretical construction, this paper conducted R&D of virtual teaching course based on WebGL from two aspects, overall framework design and 3D teaching environment building
Summary
Virtual technology as a new type technology based on multiple computer technologies and multimedia technology can simulate and virtualize the real world or objects so as to satisfy people’s demands by adjusting self-variation according to surrounding environment changes. Especially medical, PE, and design major teaching have high requirements for practical ability [3]. Virtual teaching system achieved complete simulation to a large degree by means of making the teaching course into animation with virtual technology and adding more interactivity and facticity on this basis. Current well-designed virtual teaching system has been widely used in medical experiments, engineering drawing and relevant fields, which has great significance for improving practical teaching effect. This paper conducted irtual “Mould Design” teaching course development based on WebGL technology for the purpose of compensating hardware facility deficiency in universities, and improving students’ learning interest by virtue of the interactivity and creativity of virtual technology so as to achieve better teaching effect
