In [[Mega Drive]] games, sprites can be no larger than 32x32 [[pixel]]s and use no more than 15 [[Palette|colors]] (plus 1 for transparency), so several sprites are often used by a single [[object]] (for example the Sonic object). The way sprites are arranged together in a single object is called [[sprite mappings]]. It is also possible to zoom sprites up to full screen.{{ref|http://www.polygon.com/features/2015/2/3/7952705/sega-genesis-masami-ishikawa}}

A sprite is essentially a [[wikipedia:Texture mapping|texture]], or textured rectangle.{{ref|[http://www.sfml-dev.org/tutorials/2.0/graphics-sprite.php Sprites and textures]}} Sprites can be used for both two-dimensional gameplay (as flat surfaces) and three-dimensional gameplay (with scaling, rotation and distortion). Sprites could be manipulated to resemble [[wikipedia:Texture mapping|texture-mapped]] 3D polygons, as is the case with several [[Sega]] systems, including the [[Sega Saturn]] console and the [[Sega X Board]], [[Y Board]], [[System 32]], [[ST-V]] and [[Sega H1 Board|H1 Board]] [[List of Sega arcade systems|arcade systems]]. Conversely, a texture-mapped polygon could be manipulated to resemble a 2D sprite (rendering a textured quad polygon as a flat surface), as is the case with the [[Sega Dreamcast]] console and [[Sega NAOMI]] [[arcade]] system. A texture-mapped 3D polygon itself is essentially a 3D polygon with a sprite texture applied to its surface.

A sprite is a 2-dimensional movable image that appears on the screen.

In Mega Drive games, sprites can be no larger than 32x32 pixels and use no more than 15 colors (plus 1 for transparency), so several sprites are often used by a single object (for example the Sonic object). The way sprites are arranged together in a single object is called sprite mappings. It is also possible to zoom sprites up to full screen.[1]

A sprite is essentially a texture, or textured rectangle.[2] Sprites can be used for both two-dimensional gameplay (as flat surfaces) and three-dimensional gameplay (with scaling, rotation and distortion). Sprites could be manipulated to resemble texture-mapped 3D polygons, as is the case with several Sega systems, including the Sega Saturn console and the Sega X Board, Y Board, System 32, ST-V and H1 Board arcade systems. A sprite can also be used as a texture that is applied to the surface of a 3D polygon, resulting in a texture-mapped 3D polygon. Conversely, a texture-mapped polygon could be manipulated to resemble a 2D sprite (rendering a textured quad polygon as a flat surface), as is the case with the Sega Dreamcast console and Sega NAOMI arcade system.
