point Lights
A point light, also called an area light, is a single point of light that casts light in all directions. 
Point lights can be placed behind shades, glass, and similar transparent surfaces to cast light 
through them. A point light is the simplest form of simulated lighting used in IRPs (Fig. 24.7, 
Fig. 24.8, Fig. 24.9).
Spotlights
Spotlights, also called directional lights, are emitters that cast light in a specific direction. 
Spotlights can be used to direct a light in a specific line of sight over long distances (Fig. 24.10, 
Fig. 24.11, Fig. 24.12).

Fig. 24.10: 
Most spotlights share the same configuration: a pyramidal shape. The pyra-
mid indicates the direction of the light to be emitted.

A series of spotlights are placed around the SketchUp model directed at each painting.
