Synthetic content generation for auto-stereoscopic displays

Abstract

Due to the appearance of auto-stereoscopic visualization as one of the most emerging tendencies used in displays, new content generation techniques for this kind of visualization are required. In this paper we present a study for the generation of multi-view synthetic content, studying several camera setups (planar, cylindrical and hyperbolic) and their configurations. We discuss the different effects obtained varying the parameters of these setups. A study with several users was made to analyze visual perceptions, asking them for their optimal visualization. To create the virtual content, a multiview system has been integrated in a powerful game engine, which allows us to use the latest graphics hardware advances. This integration is detailed and several demos and videos are attached with this paper, which represent a virtual world for auto-stereoscopic displays and the same scenario in a two-view anaglyph representation for being visualized in any conventional display. In all these demos, the parameters studied can be modified offering the possibility of easily appreciate their effects in a virtual scene.

Analyzing autostereoscopic environment configurations for the design of videogames

“…In [24] the authors performed user tests in a First-Person game applying different camera setups, and showed that the configuration that produces more natural and realistic sensations was the planar configuration. Following the results of [24], a planar camera setup is presented in this work. A rack of cameras was disposed, where n linearly arranged cameras are pointing toward the scene.…”

“…In this configuration, the quality of the visualization will be determined by a horizontally distributed camera configuration, where the optical axes of the cameras are always parallel (Figure 5 (a)). This arrangement is the same planar setup as the one used in [24]. The Field of Vision (FOV) of the cameras was set to 60 degrees.…”

Analysis and optimization of pixel usage of light-field conversion from multi-camera setups to 3D light-field displays

“…MV 3D displays present multiple views directly (two of which are visible at the same time with the two eyes), thus, generating the necessary views for such displays is similar to stereoscopic content creation in the sense that two selected views, which are supposed to be seen at the same time, should obey the same rules as stereoscopic content. However the views are created over a bigger baseline (the distance between leftmost and rightmost camera) [6] [7].…”
