In computer graphics, a sprite is a two-dimensional bitmap that is integrated into a larger scene, most often in a 2D video game. Originally, the term sprite referred to fixed-sized objects composited together, by hardware, with a background. [ 1 ]
25 out of 55 usable colors (12 hues by 4 luminosity levels, + 7 greys); 1 background color, four 3-color (plus transparent) tile palettes and four 3-color (plus transparent) sprite palettes. Sega Master System (1985) 32 colors out of 64 (2 bits for each of red, green, and blue) NEC PC-Engine/TurboGrafx-16 (1987) 482 colors out of 512
Shadow the Hedgehog [a] is a character created by the Japanese game developers Takashi Iizuka, Shiro Maekawa, and Kazuyuki Hoshino. He is a major character in Sega's Sonic the Hedgehog franchise. Shadow is an anthropomorphic black hedgehog created by Professor Gerald Robotnik, the grandfather of Doctor Eggman.
The other video modes are similar to the GBA, but feature some enhancements. For example, the DS provides a number of 16 extended 256 color palettes for backgrounds as well as sprites on each of the two screens, allowing for a total of 8192 colors per frame (the practical number may be less due to some of the colors being considered transparent).
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]
The models used in 2D computer graphics usually do not provide for three-dimensional shapes, or three-dimensional optical phenomena such as lighting, shadows, reflection, refraction, etc. However, they usually can model multiple layers (conceptually of ink, paper, or film; opaque, translucent, or transparent—stacked in a
Shadow buffer A synonym for shadow map. Shadow map A texture buffer holding depth values rendered in a separate render pass from the perspective of a lightsource, used in Shadow mapping; it is typically rendered onto other geometry in the main rendering pass.
