A basic diffuse lighting algorithm lies at the core of most lighting calculations. It is used to simulate the appearance of matte surfaces that reflect the light, scattering it in many different directions. In this recipe, we will see how to achieve geometry rendering using vertex and fragment shaders that implement the diffuse lighting algorithm.
