Parallax Scrolling
Parallax scrolling is a technique in computer graphics where background images move past the camera more slowly than foreground images, creating an illusion of depth in a 2D scene of distance. The technique grew out of the multiplane camera technique used in traditional animation since the 1930s. Parallax scrolling was popularized in 2D computer graphics with its introduction to video games in the early 1980s. Some parallax scrolling was used in the arcade video game ''Jump Bug'' (1981). It used a limited form of parallax scrolling with the main scene scrolling while the starry night sky is fixed and clouds move slowly, adding depth to the scenery. The following year, '' Moon Patrol'' (1982) implemented a full form of parallax scrolling, with three separate background layers scrolling at different speeds, simulating the distance between them. ''Moon Patrol'' is often credited with popularizing parallax scrolling. '' Jungle King'' (1982), later called ''Jungle Hunt'', also had p ...

Compositing
Compositing is the process or technique of combining visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live action, Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. Today, most compositing is achieved through digital image manipulation. Pre-digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century, and some are still in use. Basic procedure All compositing involves the replacement of selected parts of an image with other material, usually, but not always, from another image. In the digital method of compositing, software commands designate a narrowly defined color as the part of an image to be replaced. Then the software (e.g. Natron (software), Natron) replaces every pixel within the designated color range with a pixel from another image, aligned to appear ...

History Of Video Game Consoles (fourth Generation)
In the history of video games, the fourth generation of video game consoles, more commonly referred to as the 16-bit era, began on October 30, 1987, with the Japanese release of NEC Home Electronics' PC Engine (known as the TurboGrafx-16 in North America). Though NEC released the first console of this era, sales were mostly dominated by the rivalry between Sega and Nintendo across most markets: the Sega Mega Drive (known as the Sega Genesis in North America) and the Super Nintendo Entertainment System (known as the ''Super Famicom'' in Japan). Cartridge-based handheld game consoles became prominent during this time, such as the Nintendo Game Boy, Atari Lynx, Sega Game Gear and TurboExpress. Nintendo was able to capitalize on its success in the third generation, and managed to win the largest worldwide market share in the fourth generation as well. However, particularly in the lucrative North American market, there was a fierce console war that raged through the early 1990s, w ...

History Of Video Game Consoles (third Generation)
In the history of video games, the third generation of video game consoles, commonly referred to as the 8-bit era, began on July 15, 1983, with the Japanese release of two systems: Nintendo's Family Computer (commonly abbreviated to '' Famicom'') and Sega's SG-1000. When the Famicom was released outside of Japan, it was remodeled and marketed as the Nintendo Entertainment System (NES). This generation marked the end of the video game crash of 1983, and a shift in the dominance of home video game manufacturers from the United States to Japan. Handheld consoles were not a major part of this generation; the Game & Watch line from Nintendo (which started in 1980) and the Milton Bradley Microvision (which came out in 1979) that were sold at the time are both considered part of the previous generation due to hardware typical of the second generation. Improvements in technology gave consoles of this generation improved graphical and sound capabilities, comparable to golden age ...

Horizontal Blanking Interval
Horizontal blanking interval refers to a part of the process of displaying images on a computer monitor or television screen via raster scanning. CRT screens display images by moving beams of electrons very quickly across the screen. Once the beam of the monitor has reached the edge of the screen, it is switched off, and the deflection circuit voltages (or currents) are returned to the values they had for the other edge of the screen; this would have the effect of retracing the screen in the opposite direction, so the beam is turned off during this time. This part of the line display process is the Horizontal Blank. In detail, the Horizontal blanking interval consists of: * front porch – blank while still moving right, past the end of the scanline, * sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black". * back porch – blank while moving right again, before the start of the next scanline. Colorburst occurs during the back porch, and un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raster Graphics
upright=1, The Smiley, smiley face in the top left corner is a raster image. When enlarged, individual pixels appear as squares. Enlarging further, each pixel can be analyzed, with their colors constructed through combination of the values for red, green and blue. In computer graphics and digital photography, a raster graphic, raster image, or simply raster is a two-dimensional image or picture represented as a rectangular Matrix (mathematics), matrix or grid of pixels, viewable via a computer display, paper, or other display medium. A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. 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"). In contrast, '' line art'' is usually implemented as vector graphics in digital systems. Many raster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensible Software
Sensible Software was a British software company founded by Jon Hare and Chris Yates which was active from March 1986 to June 1999.

Color Cycling
Color (or colour in Commonwealth English; see spelling differences) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, emission, reflection and transmission. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain. Colors have perceived properties such as hue, colorfulness (saturation), and luminance. Colors can also be additively mixed (commonly used for actual light) or subtractively mixed (commonly used for materials). If the colors a ...
