With the introduction of the teaching theory of constructivism and the development of virtual 3D technology, multimedia courseware production is required to enhance the authenticity of teaching situation, expand the interaction of teaching courseware, and carry out 3D network teaching. This paper designed a constructivism-based 3D scene display teaching system. By using ASP.NET and WEB3D as the core technologies and combining SQL SERVER technology, this system can run on the Internet in the form of web pages, demonstrate and store teaching courseware, and show great advantages in human-computer interaction, three-dimensional display and advanced teaching. In specific discussion, the paper elaborated the demand of designing the system, relevant function modules and the implementation process. It has been proven that the constructivism-based 3D scene display teaching system for Wushu education has a remarkable effect on improving students’ examination results and expanding their innovation ability.

Purpose The purpose of this study is to enhance audience experience in museum by using three-dimensional (3D) virtual simulation technology. Design/methodology/approach In this study, a large space museum building tourism demonstration system based on 3D virtual simulation technology was proposed. Starting from the concept of virtual reality (VR), the characteristics of VR and the classification of VR systems were introduced, and the research status of VR technology at home and abroad and the application of 3D virtual simulation were discussed. Then the key technologies of 3D modeling, 3D scene optimization and 3D simulation driving of 3D virtual simulation were expounded, and the characteristics and application scope of different technical methods were analyzed. Finally, an example of the Hongzhou Kiln 3D network museum was listed. Findings The research results showed that 3D virtual simulation has a wide range of applications in the field of VR. Different elements need to be considered for different types of applications, and different contents need to be integrated to achieve the corresponding interaction modes. Originality/value Virtual image; multimedia; large space museum; tourism demonstration system; 3D virtual simulation technology.

In the basis of the integration of traditional and network teaching, a network teaching system based on webquest and mindmap was established. Around webquest and mindmap, the main modules of the system had been designed and a new inquiry teaching model had been established, in which the teacher-leading and student-centered idea was introduced and intellectual analysis feedback circle was designed. By inputting teaching tasks, teaching situation and teaching resources, and by means of teacher's just-in-time guidance and student's thinking and inquiry, the system could output the final complete mind maps and inquiry conclusions. The system was applied to the "principles of computer network" course and empirical research was carried out in the experimental class. The experimental results show that, the network teaching system can stimulate student's learning interest, and improve student's comprehensive qualities and innovation ability.

The course of architectural engineering drawing is the basic course before the students of civil engineering related majors study the professional courses. It aims to cultivate the students' ability of configuration, expression, reading and drawing. BIM Technology simulates the real component information of a building through digital information simulation, and flexibly transforms between two-dimensional and three-dimensional, providing a new tool for the teaching of architectural engineering drawing. This paper analyzes the characteristics of BIM Technology and teaching advantages, combined with the current teaching situation of architectural engineering drawing course, puts forward reform suggestions and implementation process, and provides reform ideas for the teaching of engineering basic courses.

At present, the comprehensive ability of Chinese internal students of Automation is not optimistic; the traditional class teaching system has great limitations in training students' innovation ability. The characteristics which include the subjectivity of learning, the openness of teaching environment, the interactivity of composition teaching and the diversity of teaching methods and teaching evaluation of interactive network teaching play a very important role in the training of innovation ability, information quality and the process of autonomous learning .

Near-eye display (NED) systems for virtual reality (VR) and augmented reality (AR) have been rapidly developing; however, the widespread use of VR/AR devices is hindered by the bulky refractive and diffractive elements in the complicated optical system as well as the visual discomfort caused by excessive binocular parallax and accommodation-convergence conflict. To address these problems, an NED system combining a 5 mm diameter metalens eyepiece and a three-dimensional (3D), computer-generated holography (CGH) based on Fresnel diffraction is proposed in this paper. Metalenses have been extensively studied for their extraordinary capabilities at wavefront shaping at a subwavelength scale, their ultrathin compactness, and their significant advantages over conventional lenses. Thus, the introduction of the metalens eyepiece is likely to reduce the issue of bulkiness in NED systems. Furthermore, CGH has typically been regarded as the optimum solution for 3D displays to overcome limitations of binocular systems, since it can restore the whole light field of the target 3D scene. Experiments are carried out for this design, where a 5 mm diameter metalens eyepiece composed of silicon nitride anisotropic nanofins is fabricated with diffraction efficiency and field of view for a 532 nm incidence of 15.7% and 31°, respectively. Furthermore, a novel partitioned Fresnel diffraction and resample method is applied to simulate the wave propagations needed to produce the hologram, with the metalens capable of transforming the reconstructed 3D image into a virtual image for the NED. Our work combining metalens and CGH may pave the way for portable optical display devices in the future.
