The Lighting Options are accessed by clicking on the Lighting Options 
item in the Display Options 
dialog. The following table describes the lighting display options.
| Display Option | Description |
|---|---|
| Enable shading | This option controls whether a light source is used in the shading process for generating shaded images. This light source controls the intensity of the colors on the shaded image and highlights the relief or geometrical variation in the surface of the objects being shaded. |
| Ambient light | Ambient light is light that comes from all directions and not a particular source. |
| Diffuse light | Diffuse light is that which comes from a particular source and direction. |
| Smooth features | This option adjusts the normals on the triangles to make the surfaces look smooth. |
| Specular highlights | Specular light comes from a particular light source and is reflected in a particular direction causing a shiny hot spot. |
| Edit light source | The sphere shown on the tab is shaded according to the current setting for the lighting options. The light angle can be changed by clicking on the sphere with the cursor at the location where a direct ray from the light source to the center of the sphere would strike the sphere. The sphere shading is updated instantaneously to reflect the chosen light angle. |
