DiffuseLightingGouraud

Diffuse Lighting in Goraud Shading

Code Name: DiffuseLightingGouraud

Description

In this example, objects of various colors are drawn on the screen, and a rotating light source is added around these objects. Diffuse lighting is applied to these objects in the scene using gouraud shading.
