Other factors, such as a lights color, intensity, attenuation, and angle of
incidence also play a role in how objects in a scene appear.
Use Point Lights
A point light radiates light in all directions from its location.
Point Lights
A point light radiates light in all directions from its location. A point light
does not target an object. Use point lights for general lighting effects. You can
create a point light by entering the POINTLIGHT command or by selecting a
point light from the Lights panel on the ribbon.
You create a target point light with the TARGETPOINT command. The
difference between the target point light and a point light is the additional
target properties that are available. A target light can be pointed to an object.
A target point light can also be created from a point light by changing the
target property of the point light from No to Yes.
In the standard lighting workflow, you can set a point light manually so its
intensity diminishes with respect to distance either linearly, according to the
inverse square of the distance, or not at all. By default, the attenuation is set
to None.
