Please give a step-by-step solution to the following problem on Computer Graphics.

Topic: Phong's Lighting Model

 

A light source with intensity 5 and radius of influence 50 is located at point (2,3,4) from
which you are called to calculate the illumination of a point on the xy plane. The camera is
set at a point (5,6,3) and the light is reflected back from point (4,4) of the plane. The
ambient, diffuse and specular coefficient is given at 0.2, 0.5, 0.4.
a. For the above phenomenon, represent the reflected ray R in the unit vector.
b. Calculate the specular reflection intensity for a shininess factor of 10.
c. Calculate the attenuation factor for the given point in the above scenario.
d. If the ambient light intensity is at 2, calculate the total reflected light intensity at the
niyen point according to phong's model with the attenuation factor.
