Implementation of Real-time Computer-generated Integral Imaging System for Head Mounted Display using OpenGL Shading Language

In this paper, the real-time computer-generated integral imaging(CGII) system for the head mounted displays(HMDs) is implemented based on the open graphics library shading language, where the integral imaging system is composed of micro display and micro lens array applicable for the HMD application. To verify the performance of the implemented CGII system, the rendering speed of the virtual objects consisting of a large number of vertices is measured. The frame rate of virtual objects with over 100,000 vertices is 30 fps, which validates the real-time operation of proposed system. Also, displaying experiments for presenting 3D virtual images are performed with the implemented CGII system with the micro display and micro lens array.
