Lesson plan
Mode 7
demo uses Mode 7 for a faux 3D perspective view. Mode 7 is a graphics mode on the Super Nintendo Entertainment System (Super NES) video game console that allows a background layer to be rotated and scaled, which may be done on a scanline-by-scanline basis to create many different depth effects. It also supports wrapping effects such as translation and reflection. The most famous of these effects is the application of a perspective effect (Figure 1) on a background layer by adjusting the layer's scale each scanline. This transforms the background layer into a two-dimensional (2D) horizontal texture-mapped plane that trades height for depth, achieving an impression of three-dimensional (3D) graphics. Mode 7 was one of Nintendo's prominent selling points for the Super NES platform in publications such as Nintendo Power and Super NES Player's Guide. Similar faux 3D techniques have been presented on a few 2D systems other than the Super NES, in select peripherals and games.
