This rendering method is also referred to as billboarding. When the illusion works viewers will not notice that the sprite is flat and always faces them. Often sprites are used to depict phenomena such as fire, smoke, small objects, small plants like blades of grass , or special symbols like "1-Up". The sprite illusion can be exposed in video games by quickly changing the position of the camera while keeping the sprite in the center of the view.
Sprites have also occasionally been used as a special-effects tool in movies. One such example is the fire breathing Balrog in The Lord of the Rings: The Fellowship of the Ring ; the effects designers utilized sprites to simulate fire emanating from the surface of the demon. Small bursts of fire were filmed in front of a black background and made transparent using a luma key. Many bursts were then attached to the surface of the animated Balrog model and mixed with simulated smoke and heat waves to create the illusion of a monster made from fire.
The term "sprite" is often confused with low resolution 2D graphics drawn on a computer, also known as pixel art. However, in addition to pixel art, sprites can be created from prerendered CGI, dynamic 3D graphics, vector art, and even text.
Likewise, pixel art is created for many purposes other than as a sprite, such as video game backgrounds, textures, icons, websites, display art, comics, and t-shirts. With the advancement in computer graphics and improved power and resolution, actual pixel art sprites are becoming increasingly infrequent outside of handheld game systems and cell phones.
Billboarding is one term used to describe the use of sprites in a 3D environment. In the same way that a billboard is positioned to face drivers on a highway, the 3D sprite always faces the camera. There is both a performance advantage and an aesthetic advantage to using billboarding. Most 3D rendering engines can process "3D sprites" much faster than other types of 3D objects. So it is possible to gain an overall performance improvement by substituting sprites for some objects that might normally be modeled using texture mapped polygons.
Aesthetically sprites might be desirable because polygons might never be able to realistically reproduce phenomena such as fire. Sprite images of fire might provide a more attractive illusion. In early video gaming, sprites were a method of integrating unrelated bitmaps so that they appear to be part of a single bitmap on a screen. The Blitter is a hardware implentation of the Painter's algorithm.
For each frame the sprites are first bit blited short for "bit block transfer" into the fast, large, double, and costly frame buffer and then the frame buffer is sent to the screen. The Blitter was renamed to graphics accelerators as more complicated rendering algorithms are used. The Blitter has a high initial cost for simple scenes. The Sprite Engine is a hardware implementation of Scanline rendering.
For each scanline the appropriate scanlines of the sprites are first copied the number of texels is limited by the memory bandwidth and the length of the horizontal retrace into very fast, small, multiple limiting the of sprites on a line , and costly caches the size of which limit the horizontal width and as the pixels are sent to the screen, these caches are combined with each other and the background. It may be larger than the screen and is usually tiled, where the tile map is cached, but the tile set is not.
For every pixel, every sprite unit signals its presence onto its line on a bus, so every other unit can notice a collision with it. Some sprite engines can automatically reload their "sprite units" from a display list. Backgrounds SMB3. Enemies SMB3. Mario and Items SMB3. Palette SMB3. Tileset SMB3. Backgrounds SMW. Enemies SMW.
