Detailed Description

The struct s_sight represents the human eye looking forwards.

For the Phong Reflection Model algorithm, this human sight has an eye vision, which is the direction where the eyes are looking at and it also has a normal vision, i.e., the perpendicular vector from where the eye vision is looking at.

normalv	Represents the normal vector of some surface.
