Returning to the Shadows settings, another important visualization tool is the Show Ambient
Shadows option. Combined with other graphic options such as edge enhancements and real-
time materials, this setting allows you to create emotive, real-time views of your project that
do not require renderings.
To activate ambient light and shadows, open the Graphic Display Options dialog box, expand
the Shadow settings, and then select Show Ambient Shadows.
The results are noticeable, particularly around the intersections of objects. Shaded elements
are embellished by highlights in the center of objects and deeper shading at the edges. The
result is almost a watercolor effect that considerably softens the shaded view. The effect can
be accentuated when combined with the option to enhance the silhouette of edges for even
more real-time effects. Figure 11.20 demonstrates the differences in effect between shadows
with and without ambient shadows turned on.
