Shininess Control allows interactive adjustment of shininess, brightness, and specular color, the color used for shiny highlights. These parameters affect most displays in Chimera (exceptions include simple lines, such as molecules in the wireframe representation). There are several ways to start Shininess Control, a tool in the Viewing Parameters category.
Shininess can be adjusted by entering a value or moving the slider. Possible values range from 1 to 128 (default 30.0). The value is proportional to how concentrated the highlights are. Lower values give a "flatter" but lighter overall image, while higher values yield more pointlike highlights.
Specular color is the color used for shiny highlights. It is a light gray by default, but can be changed by clicking the color well and then using the Color Editor. The specular color can be thought of as the color of the light shining on the items being viewed. It is added to the color that would be shown if there were no highlights (the inherent color of items being viewed, plus any shading for depth). If the color is already bright white, highlights will not be visible; if the color is green and the specular color is red, highlights will look yellow.
Brightness can be adjusted by entering a value or moving the slider. Possible values range from 0.1 to 10 (default 1). The brightness can be thought of as the intensity of light shining on the items being viewed.
Default restores the default values. Close closes the Shininess Control interface.
