Z-Sprite is a term often used for 3D environments that contain only sprites.3D Sprite is a term often used to refer to sprites that are essentially texture mapped 3D facets that always have their surface normal facing into the camera.Sprite images of fire might provide a more attractive illusion. Aesthetically sprites might be desirable because polygons might never be able to realistically reproduce phenomena such as fire.
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. Most 3D rendering engines can process "3D sprites" much faster than other types of 3D objects. There is both a performance advantage and an aesthetic advantage to using billboarding.

In the same way that a billboard is positioned to face drivers on a highway, the 3D sprite always faces the camera. 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.īillboarding is one term used to describe the use of sprites in a 3D environment. 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. However, in addition to pixel art, sprites can be created from prerendered CGI, dynamic 3D graphics, vector art, and even text. The term "sprite" is often confused with low resolution 2D graphics drawn on a computer, also known as pixel art. 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. Small bursts of fire were filmed in front of a black background and made transparent using a luma key. 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. Sprites have also occasionally been used as a special-effects tool in movies. 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. 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"). When the illusion works viewers will not notice that the sprite is flat and always faces them.
Sprites create an effective illusion when: This rendering method is also referred to as billboarding. The image can be scaled to simulate perspective, it can be rotated two dimensionally, it can overlap other objects and be occluded, but it can only be viewed from the same angle. Unlike a texture map, the sprite plane is always perpendicular to the axis emanating from the camera. More often sprite now refers to a partially transparent two dimensional animation that is mapped onto a special plane in a three dimensional scene. As three-dimensional graphics became more prevalent, the term was used to describe a technique whereby flat images are seamlessly integrated into complicated three-dimensional scenes.

That is, figures generated by either custom hardware or by software alone were all referred to as sprites. As computer performance improved, this optimization became unnecessary and the term evolved to refer specifically to the two dimensional images themselves that were integrated into a scene. Sprites were originally invented as a method of quickly compositing several images together in two-dimensional video games using special hardware. In computer graphics, a sprite (also known by other names see Synonyms below) is a two-dimensional image or animation that is integrated into a larger scene.
