| In twenty-first Century,smart phones developed rapidly,especially the Android system occupied a large market.In addition,the Android system also has a large number of applications on other types of mobile client terminals.with the Android system in the mobile terminal market share increases,its impact on the consumer market is also more powerful.In real life,various types of applications based on Android systems can be seen everywhere.Virtual reality technology is also developing rapidly.It has been involved in many fields of society,such as tourism industry,education industry,construction industry and so on.Combining the virtual reality technology,the virtual environment that is developed is the system simulation of the three-dimensional dynamic situation and the entity interaction.It has a realistic sense of three-dimensional experience.The interactivity of the operation has gradually improved the user experience of the application market.Based on Analysis of virtual reality technology and market,this topic is the core of the popular virtual reality technology at the present stage,Based on the Android system,we build the 3D model through 3ds Max and Photoshop software,The application of camera motion technology,collision detection technology,3D pickup technology,Ray tracing technology,LOD technology and Input and control technology to realize 3D virtual goods display system.Study the three-dimensional virtual display of Mao Zedong's former residence requirements as base,Through the 3D virtual object modeling technology,the overall pattern and surrounding environment of Mao Zedong's former residence are displayed in a omni-directional perspective.And realize the environment roaming through the virtual rocker operation to display the interior structure of the old house.At the same time,according to the voice function,understand the historical background of Mao Zedong's former residence.The value of this research is to display the 3D virtual Mao Zedong residence through virtual reality technology.For the performance characteristics of mobile devices,Realize virtual rocker touch control,and complete the real-time interaction of mobile phone screen in Android system.The system has a strong sense of immersion,which enables users to get the roaming experience of the virtual environment in the stereo vision.The establishment of virtual Mao Zedong's former residence roaming simulation system is the foundation of building intelligent education base and scenic spot.At the same time,the virtual exhibition of Mao Zedong's former residence of mobile terminals has the function of publicizing the national education base,and also has important popularization significance for virtual walkthrough technology. |
