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]
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
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
Scene with shadow mapping Scene with no shadows. Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics.This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces."
One key disadvantage of deferred rendering is the inability to handle transparency within the algorithm, although this problem is a generic one in Z-buffered scenes and it tends to be handled by delaying and sorting the rendering of transparent portions of the scene. [6]
Shadowgraph is an optical method that reveals non-uniformities in transparent media like air, water, or glass. It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function.
