“…En este, si se ubica un lente de color cian para observar una luz del mismo color el ojo percibe una luz blanca, igual fenómeno ocurre si intercambiamos el color del lente y luz observada. Sin embrago, si con un lente de color rojo se observa una luz cian, o viceversa, el ojo no percibe luz alguna [13] [26]. Así, para componer una imagen estereoscópica se elimina el componente rojo de una imagen de la pareja estereoscópica y los componentes verde y azul (cian) de la otra, donde la imagen estereoscópica debe ser observada por gafas con lentes de los mismos colores [10].…”

“…En el campo de la medicina podemos encontrar programas para la simulación y el entrenamiento en operaciones quirúrgicas en donde también se involucra la robóti-ca (operaciones quirúrgicas poco invasivas como en laparoscopia) [26], también estos sistemas son usados en el entrenamiento y la teleoperación de vehículos no tripulados [23]. En topografía se puede realizar la visualización de terrenos [15] en estaciones fotogramétricas.…”

“…In a related prior study, Volbracht et al [9,10] compared the effectiveness of three display methods for recognizing 3D stick models of molecules. They compared perspective viewing (not stereo), anaglyphic stereo, and frame flipping stereo with shutter glasses by measuring accuracy and time required to identify, compare, and position the models of molecules.…”

“…For identifying the number of rings on molecules for which all needed information was clearly in view, Volbracht et al [9] found that the perspective viewing method was both faster and more accurate than either stereo method. For identifying the number of rings on simple molecules that needed to be manipulated, they found no significant difference between display methods.…”

This study compared the effectiveness of a head mounted display (HMD) and anaglyphic glasses on students' ability to complete engineering graphics tasks in learning environments. The two stereo display systems were used in an introductory design and graphics class. Data related to students' subjective perceptions about the two systems and data related to students' objective performance were collected and analyzed. Results of the study reveal that students perceived that the HMD was more effective for completing technical graphics tasks than anaglyphic glasses, while there was no significant difference in students' objective performance with the two display systems. ß

“…binocular vision. This can only be recreated using 'stereoscopic viewers', such as active or passive 3D projection systems 6 . Passive 3D projection systems project two different images with a spatial disparity onto a screen; each eye views each image at the same time using polarized glasses.…”

Clinicians are accustomed to viewing conventional two-dimensional (2D) photographs and assume that viewing three-dimensional (3D) images is similar.Facial images captured in 3D are not viewed in true 3D; this may alter clinical judgement. The aim of this study was to evaluate the reliability of using conventional photographs, 3D images, and stereoscopic projected 3D images to rate the severity of the deformity in pre-surgical class III patients. Forty adult patients were recruited.Eight raters assessed facial height, symmetry, and profile using the three different viewing media and a 100-mm visual analogue scale (VAS), and appraised the most informative viewing medium. Inter-rater consistency was above good for all three media. Intra-rater reliability was not significantly different for rating facial height using 2D (P = 0.704), symmetry using 3D (P = 0.056), and profile using projected 3D (P = 0.749). Using projected 3D for rating profile and symmetry resulted in significantly lower median VAS scores than either 3D or 2D images (all P < 0.05).For 75% of the raters, stereoscopic 3D projection was the preferred method for rating.The reliability of assessing specific characteristics was dependent on the viewing medium. Clinicians should be aware that the visual information provided when viewing 3D images is not the same as when viewing 2D photographs, especially for facial depth, and this may change the clinical impression.
