Spot Light.
Library: ilvbmpflt
This class allows you to model a spot light. A spot light is a positional light with additional properties such as a direction it points to and a limiting cone which restricts the region where the light is projected. A specular exponent can be specified to allow smooth transition from lit to nonlit regions.
