Originally sprites referred to independent objects that are composited together, by hardware, with other elements such as a background. This occurs as each scan line is prepared for the video output device, such as a CRT, without involvement of the main CPU and without the need for a full screen frame buffer. Sprites can be positioned or altered by setting attributes used during the hardware composition process. Examples of systems with hardware sprites include the Atari 8 bit family, Commodore 6. Nintendo Entertainment System, Sega Genesis, and many coin operated arcade machines of the 1. Use of the term sprite has expanded to refer to any two dimensional bitmap used as part of a graphics display, even if drawn into a frame buffer by either software or a GPU instead of being composited on the fly at display time. The act of creating sprites is a form of pixel art. It is sometimes referred to as spriting, especially in the hobbyist community. When multiple smaller images are combined into a single bitmap to save memory, the resulting image is called a sprite sheet or texture atlas. HistoryeditThe use of sprites originated with arcade games. The first video game to represent player characters as human player images was Taitos Basketball, which was licensed in February 1. Midway, releasing it as TV Basketball in North America. Signetics devised the first videographics processors capable of generating sprite graphics for home systems. The Signetics 2. 63. Radofin 1. 29. 2 Advanced Programmable Video System. The Atari VCS, released in 1. The term sprite was not in use at the time. The VCSs sprites are called movable objects in the programming manual, further identified as two players, two missiles, and one ball. These each consist of a single row of pixels that are displayed on a scan line. To produce a two dimensional shape, the sprites single row bitmap is altered by software from one scan line to the next. The Atari 4. 00 and 8. Each is the full height of the displaya long, thin strip. DMA from a table in memory automatically sets the graphics pattern registers for each scan line. Hardware registers control the horizontal position of each player and missile. Vertical motion is achieved by moving the bitmap data within a player or missiles strip. The feature was called playermissile graphics by Atari. The Namco Galaxianarcade system board, for the 1. Galaxian, featured animated, multi colored sprites. It pioneered a sprite system that animated pre loaded sprites over a scrolling background, which became the basis for Nintendos Radar Scope and Donkey Kong arcade hardware and home consoles such as the Nintendo Entertainment System. According to Steve Golson from General Computer Corporation, the term stamp was used instead of sprite at the time. The Elektor TV Games Computer was an early microcomputer capable of generating sprite graphics, which Signetics referred to as objects. The term sprite was first used in the graphic sense by one of the definers of the Texas Instruments. A video display processor VDP. The term was derived from the fact that sprites, rather than being part of the bitmap data in the framebuffer, instead floated around on top without affecting the data in the framebuffer below, much like a ghost or sprite. By this time, sprites had advanced to the point where complete two dimensional shapes could be moved around the screen horizontally and vertically with minimal software overhead. The CPU would instruct the external chips to fetch source images and integrate them into the main screen using direct memory access channels. Calling up external hardware, instead of using the processor alone, greatly improved graphics performance. Because the processor was not occupied by the simple task of transferring data from one place to another, software could run faster and because the hardware provided certain innate abilities, programs were also smaller.

D renderingedit2. D images with alpha channels constrained to face the camera may be used in 3. D graphics.
