Additional Info:
A spotlight emits a cone of light. Only objects within the cone are illuminated. The cone produces light of two degrees of intensity, with a central brightly lit section (the umbra) that acts as a point source, and a surrounding dimly lit section (the penumbra) that merges with the surrounding deep shadow.
The phi angle is the angle of the penumbra. The allowed range of phi is [Theta, o]. The default for theta and phi are o/2 and o respectively.
