The brain, the tridimensional vision, and the techniques to obtain stereoscopic images

Abstract

In this review article the authors discuss initially the evolutionary developmentand the ocular and neural mechanisms involved with the stereoscopic tridimensional vision, and then describe with more details the different current techniques available to obtain, to print, to project and to see in computer monitors stereoscopic images. The article finishes mentioning the experience of the Clinical Anatomy Discipline of the Department of Surgery of the University of São Paulo Medical School in developing stereoscopic teaching images, utilizing the anaglyphic technique for printing and the polarized technique for projections, both currently done through digital technology. Sketches and anaglyphic images are shown along the text.
