Give the Rendering Equation in both formulations and explain all its terms!
Hemisphere Formulation
: Incoming radiance at point 
from direction 
: Emitted radiance
: Hemisphere over the surface at point
: Intersection point of ray starting at with direction 
with the scene
: BRDF: portion of light which enters from direction at that is reflected into direction
: Angle between and the normal vector of the surface at
