 ===== General Introduction =====
+==== Rendering vs Light Modelling ====
+**Rendering** is the process of generating a (final) image (or a series of images) from a 3D scene. This includes computing how surfaces appear based on materials, lighting, camera position, and other visual effects.
+**Light Modelling** refers to the mathematical and physical simulation of how light behaves in a 3D environment, particularly how it interacts with objects (reflection, refraction, absorption, scattering).
+^ **Feature**  ^ **Rendering**  ^ **Light Modelling**  ^
+| **Goal**  | Create image | Simulate realistic light behaviour |
+| **Focus**  | Visual output | Physical correctness and realism |
+| **Includes** | Shading, camera, rasterization | Reflection, refraction, light transport |
