projective discrete methods (hemicube, tetrahedron, cartesian infinite plane, etc). This
method is classified within the methods based on Nusselt's analogy by infinite plane like
Sillion's and Puech's. The main characteristics and advantages of the method we propose
are the possibility of sub-dividing the plane into several form factor areas in an exact manner
and the continuous treatment of one of the variables, the angular. This treatment is …
