Swap operation.
The ambient color emitted by this light.
The value specifying how the light intensity changes over distance. Valid values range from 0 to infinity. Attenuation values are ignored for directional lights. For non-directional lights, all three attenuation values should not be set to 0 at the same time.

The diffuse color emitted by this light.
The direction that the light is pointing in world space. This member has meaning only for directional and spotlights. It has to be normalized and should have a nonzero length.
The decrease in illumination between the inner cone (angle theta) and the outer cone (angle phi) of a spotlight. The effect of falloff is subtle. Furthermore, a small performance penalty is incurred by shaping the falloff curve. For these reasons, falloff should have a value of 1 mostly.
The angle, in radians, of a spotlight's outer cone (illumination bound). This value must be between 0 and pi.
The position of the light in world space. This member has no meaning for directional lights.
The distance beyond which the light has no effect. The maximum allowable value is the square of FLT_MAX. This member does not affect directional lights.
The specular color emitted by this light.
The angle, in radians, of a spotlight's inner (fully illuminated) cone. This value must be in the range from 0 through the value specified by phi.
The type of the light source.
