Resumen
The article focuses on the realization of 3D visualization, using crossed-beam volumetric displays. The human body can extract enormous amounts of information about its environment from a single sensory input, which is sight. Because human beings obtain over 70 percent of their sensory input visually, researchers judge shape, size, distance, relative position, movement, speed, and a host of other physical attributes using the binocular vision provided by the two eyes. In addition, the human visual system works in real time, enabling researchers to interpret a 3D world that is changing rapidly. The perceive depth through stereopsis, motion parallax, focus, and eye convergence is more reliable and useful than the visual cues present in current 2D displays using relative size, superposition and lighting. Electronic display such as the cathode-ray tube and the liquid crystal display present visual information on flat surfaces. This article describes fundamentally different display hardware, called a crossed-beam display, which enables data actually to be addressed as a volume.
