Rendering - Introduction to AutoCAD 2011: 2D and 3D Design - page 302

Any number of the three types of lights - Point , Distant and Spotlight -
can be positioned in 3D space as wished by the operator.

In general, good lighting effects can be obtained by placing a Point
light high above the object(s) being illuminated, with a Distant light
placed pointing towards the object at a distance from the front and
above the general height of the object(s) and with a second Distant light
pointing towards the object(s) from one side and not as high as the fi rst
Distant light. If desired Spotlights can be used either on their own or in
conjunction with the other two forms of lighting.
