rendering_primitive

position is the position of the light in 3-space.

focal_point is the point at which the light is aimed.

intensity is the brightness of the light.

color is the color of the light.

status indicates whether or not the light is turned on.

position= (x,y,z) sets the position of the light.

position? returns the light's position.

focal_point= (x,y,z) sets the focal point of the light.

focal_point? returns the light's focal point.

color= (r,g,b) sets the color of the light.

color? returns the light's color.

intensity=i sets the intensity of the light (max of 1).

intensity? returns the light's intensity.
