Examples of com.jme3.light.PointLight

com.jme3.light.PointLight
Represents a point light. A point light emits light from a given position into all directions in space. E.g a lamp or a bright effect. Point light positions are in world space.
In addition to a position, point lights also have a radius which can be used to attenuate the influence of the light depending on the distance between the light and the effected object.
