Rendering
Introduction
Rendering is a term which is used in computer graphics very often. It's the process of creating an image out of an abstract model of this image (e.g. polygon mesh). The shape in this abstract model is represented by many points. After the rendering process, the picture is not represented by different points anymore, but with a (realistic) surface. This process needs a lot of computing power, especially if you want to create a realistic environment and realistic objects with different light sources.
Techniques
There are several different techniques, how you can do the rendering. The following should give you a small overview of the most common techniques.
Wire Frame
This is not a special rendering technique, but it's the basics for the rendering. The object is represented through different points which are connected. The surface of the object is described with lines.
