This tutorial will lead you through the creation of a POV simple scene. There are also several books available at your local bookstore that provide more detail than I am able to present here. Every POV scene requires a camera definition. The location coordinates tell where POV should put the camera. The remaining coordinates are described in more detail in the POV documentation.
Most scenes require three or more lights to bring out the form of the objects in the scene.
It is tempting to add many lights to a scene but each additional light increases the number of calculations the computer must do to render the scene. Too many light sources can also be confusing to the viewer. Effective lighting helps establish the mood of the scene and shadows can even be an important part of the scene's composition. You should experiment constantly with different lighting techniques. Now we need some objects.
