4.1 - Falloff Exponent

This example illustrates the use of a Falloff Exponent to control the falloff of a light. Falloff is defined as the rate at which light loses its energy as it travels away from its source. When not using Inverse Square Falloff, which is described in Example 4.2, this number is used as an exponent, providing Exponential Falloff. Exponential Falloff can often get close to realism, but will generally be best for stylized visuals.
