First, let’s look at the traditional CRT computer monitor (the heavy ones with the large cone-shaped back, which were typical in the 1980s and 1990s). As with CRT televisions, CRT computer monitors send a stream of electrons that bombard a net of phosphors located on the back of the computer screen. A phosphor is simply a substance that illuminates light when hit with an electron. Tiny red, green, and blue (RGB) phosphors group together to form what we would consider a single pixel. 6. RGB colors combined: magenta, yellow, cyan, and white are all clearly visible in the crystals.

1 Display UV Coordinates Often various-sized source images will be used for deploying the same game to various platforms. For example, large textures may be used when deploying the game to a desktop computer with a powerful graphics card, whereas smaller textures may be used when deploying the same game to mobile devices. 4) the coordinate system so that the top-left pixel is set to be (0, 0) and the bottom-right pixel is set to be (1, 1). As a result, any individual texel can be measured in terms of percentage from the origin along the U (normalized X) and V (normalized Y) axes.
