Detailed explanation-1: -Definitions: Shading model – technique that defines when and where do we calculate the components needed for light calculations. Lighting model – technique that defines how do we calculate the final color given all the components required for it.

Detailed explanation-2: -Phong shading leads to realistic-looking objects. Moreover, three-and four-dimensional objects can be viewed with perspective, orthogonal, hyperbolic and spherical projections. The appearance and display of geometric data can also be controlled through software.

Detailed explanation-3: -Shading is the process in rendering that consists of computing the color of objects in the 3D scene. In rendering we are interested in reproducing the shape, the visibility and the appearance of objects as seen from a given viewpoint.

Detailed explanation-4: -Lighting and shading is important for realistic look rendering. This work is presented the overview of lighting sources, reflection models and shading model which can be applied in computer graphics. Moreover the examples of those formulations are also discussed.
