Rendering is a system that creates a high quality three dimensional view of your scene, taking into account light levels, beams, smoke levels, reflections and shadows.
Once completed your rendering is fixed and you cannot change anything about it. To do this you have to switch down to a lower graphics level and then render it again.
The rendering process is quite complex and takes a lot of computer power to complete. As a result it can take quite some time, even several hours on slower systems or with very large or complex scenes.
To speed this process up there is a system called Fast-NetRendering, which utilizes several computers over a network in order to speed up the process, this is covered in a separate section.
A rendering is a computer generated image of your scene that works out what exactly would come out of each fixture and what that light would do to any surface it hits.
