Introduction
Welcome to the Blender Cycles: Lighting and Rendering Cookbook. Before we start, I would like to talk about the new Blender rendering engine.
Cycles is a brand new unbiased rendering engine based on the path tracing algorithm that Blender has provided to users. It is still under heavy development but is growing really fast and is already capable of creating astonishing images.
Path tracing is an algorithm that computes how light travels in an environment in a very accurate way. For this reason, it is also a pretty heavy rendering algorithm. The good news is that Cycles can rely on modern video card power to make rendering times shorter.
Cycles also has a Global Illumination (GI) system. GI is a system that is used to simulate the bouncing ...
