Vergence

When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes. To look at an object closer by, the eyes rotate towards each other (convergence), while for an object farther away they rotate away from each other (divergence). Exaggerated convergence is called cross eyed viewing (focusing on the nose for example) . When looking into the distance, the eyes diverge until parallel, effectively fixating the same point at infinity (or very far away). As opposed to the 500°/s velocity of saccade movements, vergence movements are far slower, around 25°/s. Types[edit] The following types of vergence are considered to act in superposition: Tonic vergence: vergence due to normal extraocular muscle tone, with no accommodation and no stimulus to binocular fusion. Autostereogram.

A random dot autostereogram encodes a 3D scene which can be "seen" with proper viewing technique ( ). Click on thumbnail to see full-size image. Cross-eyed vergence ( ).[1] Arrow indicates accommodation. The simplest type of autostereogram consists of horizontally repeating patterns (often separate images) and is known as a wallpaper autostereogram. Autostereograms are similar to normal stereograms except they are viewed without a stereoscope. History[edit] In 1838, the British scientist Charles Wheatstone published an explanation of stereopsis (binocular depth perception) arising from differences in the horizontal positions of images in the two eyes. Brewster also discovered the "wallpaper effect". In 1939 Boris Kompaneysky[5] published the first random dot stereogram containing an image of the face of Venus,[6] intended to be viewed with a device. How they work[edit] Simple wallpaper[edit] This is an example of a wallpaper with repeated horizontal patterns.

Una alternativa menos engorrosa es utilizar también dos fotografías, pero aprovechando la técnica de cruzar los ojos (ponerse turnio o enfocar más allá de la imagen).

Como en el caso anterior, la segunda foto debe ser tomada con un leve desplazamiento hacia la derecha, pero ahora hay que ajustarles el tamaño y pegarlas una al lado de la otra. Recuerda que la diferencia entre una foto y otra no debe ser más allá de 3 centímetros y siempre saca la izquierda antes que la derecha, para que después recuerdes cuál es cuál. En un programa de edición de imágenes, pega ambas fotografías una al lado de la otra (la derecha debe estar a la derecha) y achícalas con la lupa hasta que se vean de unos 4 centímetros de ancho. El proceso es bastante sencillo, lo difícil es "concentrase" lo suficiente para desenfocar los ojos y lograr ver la imagen en 3D. La idea es superponer una imagen sobre la otra, una tarea que a veces requiere algo de esfuerzo.

He claims he was never paid by the promoter for losing his mask, so he has the right to continue wearing it. In at least one occasion, the commission objected to this.

ASCII stereograms are a form of ASCII art based on stereograms to produce the optical illusion of a three-dimensional image by crossing the eyes appropriately using a single image or a pair of images next to each other. To obtain the 3D effect (in Figure 1 for instance), it is necessary for the viewer to diverge their eyes such that two adjacent letters in the same row come together ( ). To help in focusing, try to make the two capital Os at the top look like three. Ensure that the image of the central dot is stable and in focus. Once this has been done, look down at the rest of the image and the 3D effect should become apparent. Figure 1: Near and far distances.
