| Light Source properties |

|
A light source casts a beam of light on an exact
point in the scene, similar to a spot light in a
theater. It is possible to have different light
sources in the model, each with its own intensity,
aperture and attenuation.
|
| |
|
|
|
|
|
 |
| |
| In this example, the text boxes show
some values of the selected light source, such as its Aperture, Color
and intensity. The values can be directly modified and every variation
interactively updates the View. |
