Orientation page
The 'Orientation' page looks like this
Light-sources orientation
This page looks a lot like the page described in Primitive Properties . The difference is the 'Focus Point' fields instead of the size. The 'Focus Point' fields can be used to focus the spot on a known position.
Settings page
The 'settings' page is the dialog where you set up a light-source. It looks like this
Spot settings
In this page you can change the color of the light-source, change its intensity and change its beam angle. The color of the light-source is changed in the same manner as the 'Color Selection '. The intensity is change with the slider, or by typing in the correct percentage, and the beam angle can be changed by moving the wheel or typing in the correct value.
Below the fader you see an option labeled 'On'. This option is used to turn the light on or off. In the drawing you can recognize light-sources that are on, by a beam. Light-sources that are turned off have no beam.
The settings of the light-sources will be stored with the object. New objects will use the light settings that are in effect at the time you created the object.
