Design And Implementation Of Glasses-free 3D Play System On Web Platform

Recent years,autostereoscopic,display technology has developed rapidly and has affected our life in all aspects.Autostereoscopic display technology can be divided into four categories:Wearable stereoscopic display,holographic display,volume 3D display and plane autostereoscopic display.Binocular parallax principle in plane autostereoscopic display has been the most widely used one.This system takes unity3d as the development platform and combines autostereoscopic display with WebGL to design and implement glasses-free 3d play system,which is developed based B/S structure and includes user management module.Firstly,the background and research status all over the world of autostereoscopic display and WebGL technology are described.During the process of designing and implementing the system,some technologies which are illustrated in the second part are used.According to functional requirements and user interface requirements,the architecture of system,the structure of functions and the structure of project are designed.There are four functional modules which make up this system.This thesis illustrates how to realize these modules step by step.Finally,some tests are carried out and the demonstration of the system is attached.The system realizes the measurement of grating parameters on the web,the video of which resolution is 1920 × 1080 can be played smoothly in the system,complex model with 1m patches can be displayed stably.Viewers can obtain three-dimensional viewing effect without wearing any equipment.Users can use these functions after logging in the website and registering without installing additional plugins or complex environment configuration.This thesis combines autostereoscopic display technology with WebGL technology to realize glasses-free 3d play system.This system can measure parameters of grating,play 3D videos and 3D models without glasses,which greatly facilitates the work of stereo display.
