"the pixel color is equal to the texture map multiplied by the light map." Those who have studied mathematics should know that this is an equation. Since we do this once for each pixel, we may say that we are multiplying the texture maps themselves.Īt this point, we should abandon pseudocode in favor of something with the same meaning – but a more compact form: To find the pixel color, we multiply the values of the texture map and light map. P stands for "pixel color", T for "texture color", and L for "light map color": P.r = L.r * T.r // red In this example, I will use pseudocode because it is familiar to programmers. Let’s look at what happens to one pixel when a light map is multiplied with a texture map. Therefore, when the light map is multiplied with the texture map, shadows become black and the rest stays essentially the same:
In a light map, shadows are black and the rest is bright. Because white has the value one, multiplying it with any other color does not change the color:īecause black has the value zero, multiplying it with any other color changes the color to black: At these times, it helps to think of colors as numbers between zero and one, with black having the value zero and white having the value one. Let’s use light mapping to acquaint ourselves with multitexture:Ī light map is multiplied with a texture map to produce shadows. Multitexture is also the key to the Quake 3 graphics technology I will discuss. Multitexture refers to the act of mixing two or more texture maps to create a new texture map. Light mapping is also an early example of multitexture in computer games. Without the detailed shadows made possible by light mapping, it is very difficult to convey a sense of depth or realism, especially when texture maps repeat. Light mapping is one Quake technology that changed the computer game industry forever. This will change utterly upon the release of id software’s "Quake 3", the first computer game engine known to grudgingly accept 3DFX as a minimum requirement.

"Finally," they said, "all games will look equally good, and then gameplay will rule the marketplace." In May, 1998, these words bear a whiff of truth: games without new graphics technology regularly blow people away simply by supporting 3DFX. When cheap 3D hardware acceleration began to proliferate, computer game designers who don’t understand graphics technology breathed a sigh of relief. Note! the web server was corrupting the photoshop files.
