Bump mapping relies on light-reflection calculations to create small bumps on the surface of the object in order to give it texture; the surface of the object is not changed. Bumps are applied by matching up a series of grayscale pixels with colored pixels on the rendered, colored object. Lighter grayscale pixels create a sense of maximum relief or maximum indentation; darker pixels have less effect. A computer must contain a supporting 3D graphics card when it runs an application that has been coded to include bump maps. If the graphics card does not support bump mapping, then the bumps won't be seen. In the case of computer games, the programmer usually will code an alternate version that doesn't use bump maps. This version will look flatter and less real.   Bumpy  This slick applet uses a "bump map" to create the effect of a spotlight passing over an image. Put your own unique logo in the spotlight!
