Design And Implementation Of Science And Technology Museum Virtual Experience System Based On VR Technology

With the evolution of the world economy from agricultural economy,industrial economy,service economy to experience economy,people are not satisfied with the one-way experience of visual appreciation,but they are pursuing real-experience interactive entertainment and teaching methods for science and technology museums.The requirements are getting higher and higher.In this paper,the existing system simulation technology based on interactive 3D dynamic vision and physical behavior has been extensively researched and deeply analyzed,aiming to explore the application research of VR virtual technology in the interactive display of exhibits in Science and Technology Museum.Through the discussion of this article,we can find a set of ideal solutions for solving the virtual experience display of the current scientific and technological exhibits display design,to enrich the exhibits of the Science and Technology Museum exhibits,and to meet the display needs of visiting the exhibits of the Science and Technology Museum.The specific research contents include: firstly,according to the principles and objectives of the demand analysis,the system is divided into the science and technology museum district introduction,the science and technology museum exhibition area navigation,the science and technology museum exhibits science popularization,the exhibits 3D panoramic display area,the independent roaming area,and the navigation roaming area.The function module analyzes and designs the requirements of each functional module of the system,proposes the system design scheme architecture,and prepares the requirements before the system design.Combined with VRML language technology,3DS MAX software technology,VRPlatform software technology to jointly form the basic technical foundation of 3D roaming scene.The 3D model is transformed by VRML language technology,and the constructed 3D scene model is displayed on the VRPlatform platform to complete the 3D scene interaction in the system.Then,based on the constructed virtual experience interaction model of the science and technology museum,the anti-collision detection algorithm of the binary tree structure hierarchical bounding box is used to create a three-dimensional scene that can move reasonably for the three-dimensional geometric elements in the virtual scene,and the threedimensional scene in the system is improved.The authenticity of the interactive movement.Finally,the virtual experience system of the Science and Technology Museum is used to implement the interactive application of the VR scene through the Android platform.The way of interacting with the mobile phone allows the user to experience the virtual scene of the Science and Technology Museum,and at the same time realize the control and interaction of the exhibits,the pavilion,and the scene of the Science and Technology Museum.The system uses VR technology to provide technical support for the virtual roaming of the Science and Technology Museum,and prevents collisions and collisions of people in the roaming process through the collision detection algorithm of the binary tree structure bounding box to provide a better roaming experience for the system.With the help of the virtual experience system of the Science and Technology Museum,you can visit the Science and Technology Museum anytime and anywhere without the control of time and place,and you can improve the authenticity of visiting.
