Modular art is art created by joining together standardized units to form larger, more complex compositions.In some works the units can be subsequently moved, removed and added to – that is, modulated – to create a new work of art, different from the original or ensuing configurations.
This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
The aqua circle is the light source as it would be seen if there were no lens, while white spots are the multiple images of the source (see Einstein ring). A gravitational lens is matter, such as a cluster of galaxies or a point particle , that bends light from a distant source as it travels toward an observer.
As shown in Fig. 3a and 3b, the observer has a direct view of mirror M 1 seen through the beam splitter, and sees a reflected image M' 2 of mirror M 2. The fringes can be interpreted as the result of interference between light coming from the two virtual images S' 1 and S' 2 of the original source S. The characteristics of the interference ...
Several measures of light are commonly known as intensity: Radiant intensity, a radiometric quantity measured in watts per steradian (W/sr) Luminous intensity, a photometric quantity measured in lumens per steradian (lm/sr), or candela (cd) Irradiance, a radiometric quantity, measured in watts per square meter (W/m 2)
Human image synthesis is hard to tell apart from a human imaged with an imaging technology . Digital Emily presented to the SIGGRAPH convention in 2008 was a project whereby the reflection field of actress Emily O'Brien was captured using the USC light stage 5, [3] and the prerendered digital look-alike was made in association with Image Metrics.
When a centered fill strategy is used the ratio is created by overlapping the key light over the foundation of fill. A key source of equal incident intensity to the fill, overlapping the even fill, [clarification needed] will create a 2:1 reflected ratio (1 key + 1 fill over 1 fill) = 2:1. The same two equal incident strength sources placed on ...
A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. [1] Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from continuous tones).
