+  "text": "In a nutshell, rendering in the field of 3D computer graphics means that we generate an image or multiple images for animations out of our raw 3D scene. In the rendering process, different things will be calculated like correct display of light, shadows, material properties like reflections, refractions and so on. The rendering process will be executed by the render engine. Depending on the hardware setup and the render engine, the rendering process can range from real time where you can see the final result immediately to very long render times from minutes up to hours or even days. In Blender we have two main render engines which are the EV and the cycles render engines. EV which stands for extra easy virtual environment engine is a kind of real time renderer which can display the 3D scene with all kinds of fancy real time effects like shadows, reflections, refractions and so on in the 3D viewport. But if you output a final image or animation the rendering process is not real time but most of the time the rendering process just takes a few seconds. So it's still pretty fast. Cycles however is a physical based render engine that means light shadows, reflections and so on will be calculated more or less physically accurate by tracing the path of rays through the 3D scene. In plain English that means we can get very realistic results but the rendering process can take very long. You will learn a bit more about some of the differences between EV and cycles throughout this chapter here. The good thing is that nearly everything you set up in cycles or EV will also work in the other engine except for the render settings. That means if you set up your 3D objects, the lights, the materials and so on, this will work both in EV and cycles. That means you can basically switch the render engine at any point in your 3D production. In the following videos, we will take a closer look mainly in the render settings of EV, but we will also take a quick look into the cycles render settings.",
