Physically based rendering from first principles
Physically based rendering from first principles In this interactive article, we will explore the physical phenomena that create light and the fundamental laws governing its interaction with matter. We will learn how our human eyes capture light and how our brains interpret it as visual information. We will then model approximations of these physical interactions and learn how to create physically realistic renderings of various materials. Chapter 1: What is light? We are all familiar with light: it’s the thing that allows us to see the world, distinguish colors and textures, and keeps the universe from being a dark, lifeless void. But precisely defining what light is has proven to be a tricky question. Throughout history, many philosophers (and later, physicists) studied light in an…
