Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [ 1] Visual thinking has been described as seeing words as a series of pictures. [ 2][ 3] It is common in approximately 60–65% of the general population. [ 1] ". Real picture thinkers", those who use visual ...
Keith Watson (played by Ricky Smith) is a member of the Electric Company who can generate images in mid-air, which especially comes in handy when explaining difficult words, and can also magnify images as well. Keith is logical and level-headed and frequently creates solutions for dealing with the Pranksters' tricks.
X-ray optics. X-ray optics is the branch of optics that manipulates X-rays instead of visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and ...
Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a ...

Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.
We've all grown up thinking that sitting too close to the television is damaging to our eyes ... but that might not be the case. Technology spawns lots of confusion ... and a few affectionately ...
Entoptic phenomena (from Ancient Greek ἐντός (entós) 'within' and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz 's words: "Under suitable conditions light falling on the eye ...
The idea behind ray casting, the predecessor to recursive ray tracing, is to trace rays from the eye, one per pixel, and find the closest object blocking the path of that ray. Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.
