Abstract

Autostereoscopic monitors generally require complicated image pattern creation based on reprocessing of multiple scene views. The computational power necessary for such reprocessing is very high when real-time output of images is required at refresh rates higher than 24 fps and at high output resolutions from 1600x1200, to as much as 3840 x 2400. The optimal method is to do such reprocessing by the help of graphic card HW and not by CPU. We solved output creation for 3 types of autostereosopic monitors: generic autostereoscopic monitors requiring column-interlaced pattern, the Sharp RD3D autostereoscopic notebook, and monitors based on StereoGraphics SynthaGram principles. OpenGL stencil buffer operations were used for implementation of the output for monitors requiring column-interlaced patterns as well as output for Sharp RD3D notebook. We have tested 3 different implementations of SynthaGram like pattern creation - pure fixed pipeline OpenGL 1.2 method, nVidia Cg based GPU programming method, and a method using a mixture of both approaches. Benchmarking of all methods on different nVidia graphic card models were made. We were primary focused on application for multi-view stereoscopic video processing in DepthQ Stereoscopic Media Server software during the development, but identical methods as used for video could be employed for real time CG scene reprocessing.
