Thanks for replying...

I mean reflectivity pattern here as BACK SCATTERING effect of the objects in the
scene. Like calculation of single, double and triple bounce effect from the
ray.. When all these effects are summed together we get, back scattering effect
of the object.I need reflectivity map of any 3D modeled object. I may not
require to consider the effects of interference. Just a simple creation of
reflectivity map of any object/ scene. Thank you.
