Abstract

This paper presents the building of a stereoscope, which is formed with two parallel walls. The building of this stereoscope is based on the Wheatstone–type stereoscope. Due to the incorporation of some characteristics, we named this stereoscope "Wheatstone–Mora" environment. We propose to build stereoscopic environments of different sizes, in which, each wall can be built with projection screens, TV screens, and/or computer–controller monitors connected via network, and display a stereoscopic scene on them. We incorporate means performing unrestricted navigation around the 3D scene. This navigation can be controlled through several different input devices: a keyboard, a tracker, and a remote control. Furthermore, the user can move within the physical environment as long as he/she is always at the same distance from both walls. Finally, we evaluated, analyzed and showed the results of our environment.

Keywords: Stereoscope, Virtual Environment, stereographic.

 

Resumen

Este artículo presenta la construcción de un estereoscopio, el cual está formado con dos paredes paralelas. La construcción de este estereoscopio está basado en el estereoscopio tipo–Wheatstone. Debido a la incorporación de algunas características, lo nombramos ambiente Wheatstone –Mora. Proponemos construir ambientes estereoscópicos de diferentes tamaños, en los cuales, cada pared será construida con pantallas de proyección, televisiones, y/o monitores controlados por computadora conectados a una red, y visualizar una escena estereoscópica sobre estos. Incorporamos medios de navegación sin restricciones a través de la escena 3D. Esta navegación puede ser controlada a través de varios dispositivos de entrada: un teclado, un tracker y un control remoto. Además, el usuario puede moverse en el ambiente físico, mientras el/ella mantenga la misma distancia en ambas paredes. Finalmente, evaluamos, analizamos y mostramos los resultados de nuestro ambiente.

Palabras clave: Estereoscopio, Ambiente Virtual, Gráficas estéreo.
