Define intensity attenuation. Distinguish between Gouraud shading and Phong shading model. [5]
--- Definition: The rate of decrease in intensity with respect to the distance between the light source and objects is called intensity attenuation. - If a point light source is used, the intensity attenuation is given by: $$\text{Attenuation} = \frac{1}{d^2}$$ where d is the distance between the...
