Primitive Light

The Primitive Light takes the form of the object you ascribe it to. The light has no representation in OpenGL whether attached to a primitive or not.

The light can simply emanate from geometry or the Sample Surface option can be used to take into account the geometry's surfacing. If you use sampled surfaces, the light color and intensity act as a multiplier for the object's luminous intensity and color surfacing
