Examples of SpotLight

com.ardor3d.light.SpotLight
SpotLight defines a light that has a location in space and emits light within a cone. This cone is defined by an angle and exponent. Typically this light's values are attenuated based on the distance of the point light and the object it illuminates.
com.jme3.light.SpotLight
Represents a spot light. A spot light emmit a cone of light from a position and in a direction. It can be used to fake torch lights or car's lights.
In addition to a position and a direction, spot lights also have a range which can be used to attenuate the influence of the light depending on the distance between the light and the effected object. Also the angle of the cone can be tweaked by changing the spot inner angle and the spot outer angle. the spot inner angle determin the cone of light where light has full influence. the spot outer angle determin the cone global cone of light of the spot light. the light intensity slowly decrease between the inner cone and the outer cone. @author Nehon

The SpotLight object specifies an attenuated light source at a fixed point in space that radiates light in a specified direction from the light source. A SpotLight has the same attributes as a PointLight node, with the addition of the following:
- Direction - The axis of the cone of light. The default direction is (0.0, 0.0, -1.0). The spot light direction is significant only when the spread angle is not PI radians (which it is by default).
- Spread angle - The angle in radians between the direction axis and a ray along the edge of the cone. Note that the angle of the cone at the apex is then twice this value. The range of values is [0.0,PI/2] radians, with a special value of PI radians. Values lower than 0 are clamped to 0 and values over PI/2 are clamped to PI. The default spread angle is PI radians.
- Concentration - Specifies how quickly the light intensity attenuates as a function of the angle of radiation as measured from the direction of radiation. The light's intensity is highest at the center of the cone and is attenuated toward the edges of the cone by the cosine of the angle between the direction of the light and the direction from the light to the object being lit, raised to the power of the spot concentration exponent. The higher the concentration value, the more focused the light source. The range of values is [0.0,128.0]. The default concentration is 0.0, which provides uniform light distribution.
A spot light contributes to diffuse and specular reflections, which depend on the orientation and position of an object's surface. A spot light does not contribute to ambient reflections.
