Simulation And Implementation Of Virtual Lab Circuit Based On Unity3d And 3dmax

As an advanced human-computer interaction technology,virtual reality technology uses computer graphics technology and stereoscopic display technology to present computer-generated virtual scenes to users,and provides user-friendly virtual and real interaction methods to provide users with immersive virtual reality.In recent years,the introduction of virtual reality technology into education is a new way.Thesis we takes STEAM education concept as the leading idea,deeply explores virtual reality technology,and applies its real immersive,interactive and conceived features to the teaching field.For the electronic circuit simulation experiment,the virtual circuit simulation laboratory of electronic circuit is realized by constructing virtual equipment,designing experimental results and realistic experimental scene.The main work is as follows:(1)Following the STEAM education philosophy,the main point of virtual reality laboratory is to highlight the five core concepts of STEAM education.Applying scientific knowledge and techniques to view and solve problems in project-based learning and problem-based learning,applying virtual reality technology and its The expansion field combined with STEAM education gives solutions for electronic circuit simulation experiments,enabling users to experience the educational ideas brought about by virtual reality labs.(2)Based on circuit simulation,the experimental content was designed,and 10 virtual circuit simulation experiments were built.The circuit board was made by Altium Designer software,and the precise virtual electronic components were built by Solidworks software.In order to improve the immersion and conception of the system,Interactivity,using powerful3 dmax software to render and bake virtual components,create virtual environments such as tables,chairs,blackboards and large-scale experimental equipment needed for virtual labs,and basically solve the static models needed for the entire virtual lab.(3)For the entire circuit simulation virtual laboratory,using the mainstream Unity3 D engine development,using the C# programming language to independently develop the system interface,perspective,electronic components.From the initial experimental environment,officially step into the virtual laboratory,through the control of the mouse and keyboard,browse the general environment of the entire laboratory,viewed the experimental equipment through text prompts,and clicked the button to realize functions such as interface jump,experiment selection,and experiment reset.The single-machine virtual instrument manipulation collision response control,the event response control of the push switch,the control of the circuit logic function,etc.are all experimental interactions,presenting the entire experimental operation process in a realistic three-dimensional perspective,combined with real circuit welding experimental scenarios.Realistic circuit simulation effects complete the development of the entire system.The virtual circuit simulation experiment based on STEAM education allows students to use five kinds of teaching knowledge to fully exert their imagination and creativity in a realistic virtual environment and open up a new world of teaching.
