Abstract

Users and researchers from different areas have been interested in the visualization of three-dimensional images based on the stereoscopic effect.

In the past few years, after the common use of stereoscopic visualization devices [2], some applications, which use the parallax phenomenon either to increase the realism of images or to improve the transmission of geometrical information to the user, have appeared. The application areas include medicine, robotics and control systems, cartography, CAD, military affairs and investigation related to human vision.

In this paper, we analyze the creation of depth sensation in flat images and we present a new method, based on the Ray-Tracing algorithm [8], and several techniques with the purpose of reducing the calculation time.

According to performed experiences and their results, this algorithm permits the creation of a stereoscopic pair of images in only 85% of the time needed to the generation of the same pair using the traditional Ray-Tracing algorithm. Together with some extra techniques that are also presented, this time can be reduced to less than 70%, with only a little loss in the image quality.
