Rendering is a crucial part of computer graphicsit is the conversion of a description of a 3D scene into a photorealistic image for display. From movies to video games, computer-rendered images are pervasive today. Incorporating ideas from a wide range of disciplines, including physics, biology, psychology, and cognitive science, Physically Based Rendering describes both the mathematical theory behind a modern photorealistic rendering system as well as its practical implementation. As each new rendering concept is described, it is also exemplified in code. This method--known as "literate programming"--combines human-readable documentation and machine-readable code into a single source specifically designed to aid comprehension. The result is a stunning achievement in graphics education. Using the ideas and software in this book, practitioners can construct and utilize a full-featured rendering system for creating stunning imagery, and researchers have a robust and up-to-date foundation for exploring the frontiers of this exciting field.
The items bear minimal signs of past use, such as light scratches or memories in the form of markings. These signs of wear give the items a charming character and tell stories of their previous owners, while not affecting their functionality.
