The simplicity and inherent robustness of the Philips 3D- LCD, both in manufacturing and usage, make it highly suitable for a cost effective, mass-market autostereoscopic display. For successful adoption in a wide range of applications, efficient 3D image preparation is very important. A generic expression for the relation between LCD pixels and the multiple perspective views is derived that can be used in the image preparation for different 3D-LCD systems. This paper then describes two approaches to 3D image preparation. One is an intuitive graphical user interface and the second is at source code programming level as an extension to the existing OpenGL 3D graphics API. Using the latter we examine the computer overhead of the 3D image preparation process.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
