Real-Time Rendering Mastery Hub: The Industry Foundation Pra

In the context of real-time rendering, what is the primary advantage of using a physically based rendering (PBR) workflow over traditional Phong or Blinn-Phong models, particularly concerning the accurate representation of light interaction with surfaces?

Within the rendering pipeline, what is the fundamental purpose of the rasterization stage, and how does it differ from ray tracing in terms of geometric processing?

When discussing shader programming in real-time rendering, what is the role of the fragment shader (or pixel shader), and what kind of information does it typically operate on?
