Ray tracing-based rendering creates by far more realistic images than the traditional rasterization-based rendering. However, it is still burdensome when implemented for a Head-Mounted Display (HMD) system that demands wide field of view and high display refresh rate. Furthermore, presenting high-quality on HMD screen, sufficient number ray sampling should be carried out per pixel to alleviate ...

postmodernism is of the third period of human’s thought eras. during this era which spans the end of the nineteenth century to the present time , “creation “of the real replaces its “ discovery”. this stream is the extremist form of modernism. it has some specific qualities such as irony and mixture of popular art and formal art. this essay aims to analyze one of arabic modern texts named “coll...

We previously reported several static three-dimensional (3-D) display implementations of the partial pixel architecture [J. Opt. Soc. Am. A 12, 73 (1995)]. We report herein our f irst real-time 3-D display based on this architecture. The display is functionally equivalent to a real-time holographic stereogram. It is autostereoscopic and provides horizontal motion parallax. The display device is...
